Question about 2003 Honda Pilot

1 Answer

Factory security system intermittently going off. Wondering if it is a bad sensor or switch. Does the door LED flash a code? 8 long flashes followed with normal short flashes.

My Pilot sat at the airport for two weeks and battery was dead when I returned. Got a jump start and drove 80 miles home. Now the security system is randomly going off and sometimes I don't get the horn beep when I push the fob twice. The led on the door flashes 8 long flashes and then pauses and then a string of short flashes. Does the alarm system flash codes on this light? Is there any way to tell what it could be before I pay Honda a lot of money to tell me what it is?

CAR ALARM ISSUES


It can be any of the car doors not got properly locked or the door is locked but the switch is not sensing the door locked. Open and close each door again properly.

Or else its problem with any of switch wiring getting in contact with alarm wiring causing it to happen.

And last thing alarm connections need to be inspected. It's getting short somewhere in between.


There are few help links with solutions, to troubleshoot these types of problems. I suggest going through these links.

SOURCE: 2002 Honda Odyssey security alarm system

Make sure your hood is shut. I just got my 2002 Honda Odyssey back from the dealer today (90,000 mile check-up - I love my van and will drive it until it dies!) and when I went to lock the van with my remote transmitter, the lights didn't flash and the horn didn't sound. I open and closed all the doors and tailgate and I could hear that the doors were locked, but the security system wasn't working and that is why the lights didn't blink or the horn didn't sound. I walked up to the front of the van to check the hood to make sure it was closed (there isn't an indicator light for an open hood, only open doors) and the hood wasn't shut completely. Once I opened the hood and let it drop to securely shut, I hit the door lock button on the remote and everything worked like a charm! Hope this helps others in this predicament.

Probably when the dealer is testing it is fine because the problem is intermittent. There may be a dead spot in the starter so when it hits that spot it acts up but other times its not on that spot its fine. Replace your starter and you will probably get rid of the problem.

Ride height specification for 2002 Bravada and procedure on replacing sensors.Or where can I look on line for this information.


Air Suspension ??????

Air Suspension Description and Operation
Air Suspension
The primary mission of the Air Suspension System is the following for the rear suspension under loaded and unloaded conditions:
• Keep the vehicle visually level
• Provide optimal headlight aiming
• Maintain optimal ride height
The Air Suspension System consists of the following items:
• Air suspension compressor assembly
• Air suspension sensors
• Rear air springs
Important: The Air Suspension System must have a voltage supply of at least 12.6V to operate properly.
The Air Suspension System will maintain the rear D height within 4 mm (0.15 in) in all loading conditions and the leveling function will deactivate if the vehicle is overloaded. The side to side D height variation is maintained within 8 mm (0.31 in). After ignition is turned off, the air suspension control module (ASCM) will remain active for between 30 minutes and 2 1/2 hours. The system will exhaust pressure within 30 minutes after the ignition is turned off to lower the vehicle after unloading. In a temperature-controlled environment, the leakage of the complete load leveling system will not result in more than 1.4 mm (0.05 in) drop of rear suspension height at GVWR during a 24 hour period. If the outdoor temperature drops from +20°C (+68°F) to -5°C (+23°F), the rear D height may drop as much as 25 mm (1 in). However, the Air Suspension System should return to the specified D height when the ignition is again cycled to ON.

What is the problem ?

Diagnostic Trouble Code (DTC) Displaying
The Air Suspension system has an internal clock to prevent overheating if the compressor assembly is running for a prolonged period of time. If the system overheats, all leveling function stops until the system cools down. During this time, the indicator LED on the air inflator switch will be quickly flashing at a constant rate.
The other three diagnostic trouble codes are displayed with a blink code on the inflator switch LED. The Air Suspension Compressor Assembly shall begin to indicate the code when the condition to cause the code becomes current.
The number of the fault code shall be represented by the number of flashing pulses on the inflator switch LED. The flashing pulses shall have a repetition rate of 0.5 seconds and each code shall be separated by a 3.0 second delay. All codes shall be flashed in the order of occurrence of the fault. The blink code shall take priority over other processes that have access to the inflator switch LED. Refer to the following:
• DTC 001
• DTC 002
• DTC 003

How to set & cancel theft deterrent system or how to set & cancel security...


Theft deterrent system (on some models)

Theft deterrent system is designed to deter vehicle theft. The system flashes the turn signal lights and turns on the interior light or the signal lights only (depending on the model), and sounds security horn and vehicle horn when it detects abnormalities such as follows:

• Any door or hood is forcibly opened.
• The batter terminal is disconnected and then reconnected
• The system control is disconnected and then reconnected.
• Abnormal impact is detected when the impact sensor function is on.

The system flashes the turn signal lights and turns the interior light or the signal lights only (depending on the model), and sounds security horn and vehicle horn if someone attempts to damage or break into your car.

Setting the system

You can set the system with or without the impact sensor function. For details, see "Canceling the impact sensor" below.

1. Turn the ignition key to "LOCK" and remove it.
2. Have all passengers get out of the vehicle
3. Push the lock (set) switch on the wireless remote control key once. At this time, the turn signal lights flashes once and the security indicator light comes on.

The system is set after 30 seconds. At this time, the security indicator light start flashing slowly.

Once the system is set, you cannot start the engine until you cancel the system.

The system will not be set in the following cases.

• When any of the door is open; security horn sounds for 1 second, close the door and set the system again.
• When the hood is open; close the hood securely.

Canceling the Impact Sensor

The impact sensor can be cancelled to prevent false alarms from being triggered incase of the following conditions:

• When parked in the noisy area
• The vehicle body or glass is subjected to a strong impact from the (such as in highly pressurized car wash).
• When transporting by a car carrier or ferry.

To cancel the impact sensor;

1. Lock the door by pushing the lock (set) switch on the wireless remote control key once, and turn signal light flash once
2. Then push the lock (set) switch twice within 5 seconds. At this time, the turn signal flash 5 times to indicate the impact sensor function is disable.

The impact sensor is deactivated as long as the system remained armed.

Canceling the system

The system will be cancelled by the following two ways:

• Turn the ignition key from "LOCK" to "ON" position.
• Unlock any of the doors by pushing the unlock (cancel) switch

If the turn signal lights flash 3 times, the system has been alarmed. Check to see if there is any abnormality with your vehicle.

If any of the doors is not opened within 30 seconds, all doors will be automatically locked and the system will be set.

When the system is set

Activating the system; When the system detects abnormalities such as follows, it flashes the turn signal lights and turns on the interior light or the turn lights only (depending on the model) and sounds the security horn and vehicle horn of 30 seconds.

• Unlocking any door without using wireless control
• Any door or hood is forcibly opened.
• The battery terminal is disconnected and then reconnected.
• The system control assembly is disconnected and then reconnected
• Abnormal impact is detected when the impact sensor function is on.

Reactivating the alarm;

Once set, the system automatically resets the alarm after the alarm stops.

The alarm will activate again under the same circumstances described in "Activating the system".

Stopping the Alarm

The alarm will be stopped by the following two ways;

• Turn the ignition key from the "LOCK" to "ON" position.
• Unlock any of the doors by pushing the unlock (cancel) switch.

The system can be cancelled by these ways at the same time.

If the battery becomes discharged due to the vehicle being unused, for a long time etc., when the battery is recharged or replaced, the system will activate the alarm. If this happens, immediately unlock any of the doors by pushing the unlock (cancel) switch, and the alarm will stop.

Testing the system

1. Set the system
2. Insert a wireless remote control key into the key hole on the driver's door handle, and unlock the door.
3. Open the door, and an alarm will sound.
4. Stop the alarm by pushing the unlock (cancel) switch.
5. Repeat this operation for the front passenger's door.

Good luck.

I have a 1998 Plymouth voyager and the climate control lights are flashing. I ran a test i found on the internet and got it down to two lights flashing(the ac and the recirculate). I got it to where the...


OK got your message on the other post (About the van) I am assuming that your Voyager is equipped with Automatic Climate Control. Follow the instructions below and you will get a better idea of what is wrong with your system.

Calibration/Diagnostics
1. To enter calibration/diagnostics test, set parking brake. Start and warm engine to normal operating temperature. With engine idling, turn blower switch to high. Turn mode switch to panel. Open all outlets. Move temperature to full cold.
2. Press and hold rear wash and rear wiper buttons simultaneously for 5 seconds (Until ALL LEDs illuminate). All LEDs should illuminate for 5 seconds. Rear wiper and intermittent rear wiper button LEDs will flash alternately during calibration/diagnostics test.
3. After approximately 60 seconds, if only the rear wiper button LED is flashing, calibration is successful and the system is okay. If rear wiper and intermittent rear wiper button LEDs are flashing, Diagnostic Trouble Codes (DTCs) are present. (See "Reading Diagnostic Codes" below)
4. To exit calibration/diagnostics test at any time, press the rear window defogger button, rear wiper button, or cycle the ignition off and then on. Test will automatically terminate 15 minutes after calibration/diagnostics is entered.

Reading Diagnostic Codes
1. Perform calibration/diagnostics test. If a DTC is present after calibration/diagnostics test has been performed, system will flash rear wiper and intermittent rear wiper button LEDs in sequence. Rear wiper represents code level, and intermittent rear wiper button LED represents code value.
2. Each time the rear wash button is depressed, rear wiper button LED wil cycle to the next code level in numeric sequence. After code level 5 is reached, rear wiper button LED will cycle back to code level 1. See table below.

Nissan pulsar 1987 n13 the ECM light came one and the car cut out and won't start again and I need to know where the ECM is


Hi, the computer is under the passenger's seat. Code extraction procedure is pasted below.


READING CODES Modes will not switch while the engine is running. The ECM automatically switches to MODE I when the ignition is switchedOFF.
1984-90 Vehicles With Dual LED System
The self-diagnostic system has 5 modes. To switch modes, switch the ignition ON and use a screwdriver to turn the mode select switch through the access port on the ECM. The inspection lights will begin to flash. When the desired mode has been entered, turn the screwdriver fully counterclockwise. The red LED and green LED perform different functions in different modes.
Mode I-
This is the normal vehicle operating mode. The green LED will indicate loop status. If the green LED is not blinking when the engine is running, the vehicle is in open loop, or the HO 2 S, O 2 S, or sensor circuit has a malfunction. If the green LED is blinking, the vehicle is in closed loop. If a malfunction takes place, the red LED and the MIL will glow, indicating a malfunction has occurred.
Mode II-
Both the red LED and green LED are used to monitor mixture ratio feedback control. The green LED will function as described in MODE I. If vehicle is in open loop, the red LED and green LED will remain on or off. In order for results to be valid, vehicle must be in closed loop. In closed loop, the red LED remains off if the system is running rich, comes on if the system is running lean, and blinks at the same time with the green LED if system is within 5% of the exact air/fuel ratio.
Mode III
-When this mode is accessed, the codes stored in the ECM's memory will be flashed by the green LED and red LED on the side of the ECM. The red LED will light first. This is the first digit of the trouble code; the green LED will flash next, showing the second digit of the code. For example: 2 flashes of the red LED followed by 1 flash of the green LED corresponds to Code 21.
Mode IV-
This mode is used for checking the throttle plate (TP) switch, starter, and vehicle speed switch status. When the TP switch or starter switch is activated, the red LED will briefly flash as the status changes. For VSS status, the green LED will remain off when vehicle speed is less than 12 mph (19 km/h) and come on when vehicle speed is greater than 12 mph (19 km/h).
Mode V-
This mode represents a real-time diagnostic test of the crank angle sensor, ignition signal and the mass airflow signal. The malfunction code will be displayed only when the malfunction occurs and will not be stored in memory. The output code will appear as a single or short string of pulses. Count the number of pulses for the malfunction code.



1 pulse-CMP sensor signal lost or noise in signal 2 pulses-MAF Sensor signal abnormal 3 pulses-Fuel pump circuit shorted or open 4 pulses-Ignition signal lost

Antitheft and Alarm Systems: Description and Operation
ANTI-THEFT
The passive anti-theft system (PATS) uses radio frequency identification technology
to deter a driveaway theft. Passive means that it does not require any activity from
the user.
The PATS uses a specially encoded ignition key. Each encoded ignition key contains a
permanently installed electronic device called a transponder. Each transponder
contains a unique electronic identification code, with over 72 million billion
combinations.
Each encoded ignition key must be programmed into the vehicle powertrain control
module (PCM) before it can be used to start the engine. There are special diagnostic
procedures that must be carried out if new encoded ignition keys are to be
configured.
The encoded key is larger than a traditional ignition key. The key does not require
batteries and should last the life of the vehicle.
The transceiver module communicates with the encoded ignition key. This module is
located behind the steering column shroud and contains an antenna connected to a
small electronic module. During each vehicle start sequence, the transceiver module
reads the encoded ignition key identification code and sends the data to the PCM.
The control functions are contained in the PCM. This module carries out all of the
PATS functions such as receiving the identification code from the encoded ignition
key and controlling engine enable. The PCM initiates the key interrogation sequence
when the vehicle ignition switch is turned to ON or START.
The PATS function uses the PCM to enable or disable the engine. All elements of PATS
must be functional before the engine is allowed to start. If any of the components
are not working correctly, the vehicle will not start.
PATS uses a visual theft indicator located on top of the instrument panel. This
indicator will prove out for three seconds when the ignition switch is turned to ON
or START under normal operation. If there is a PATS problem, this indicator will
either flash rapidly or glow steadily (for more than three seconds) when the ignition
switch is turned to ON or START. PATS also "flashes" the theft indicator every two
seconds at ignition OFF to act as a visual theft deterrent.
The PATS is not compatible with aftermarket remote start systems, which allow the
vehicle to be started from outside the vehicle. These systems may reduce the vehicle
security level, and also may cause no-start issues. Remote start systems must be
removed before investigation of PATS-related no-start issues.

The PATs key is used on the following Ford family trucks and suvs:

FORD: 1996-2001 MUSTANG, TAURUS
1998-2000 CONTOUR
1998-2001 CROWN VICTORIA
2000-2001 FOCUS
2002 THUNDERBIRD
1997-2001 EXPEDITION
1998-2002 EXPLORER
1999 F-250 LD
1999-2001 F-150, RANGER, WINDSTAR

1998-2000 MYSTIQUE
1998-2001 GRAND MARQUIS
1999-2001 COUGAR
1998-2002 MOUNTAINEER

Additionally, PATs can be found on the follow Ford family cars and mini-vans:

1998-up Contour
1997-up Crown Victoria
1999-up Escort
2000-up Focus
1996-up Mustang and Taurus
1998-up Windstar

1998-up Lincoln Mark VIII, Lincoln Continental and Lincoln Town Car
1997-up Mercury Grand Marquis
1998-up Mercury Mystique
1996-up Mercury Sable

Following are the instructions for programming a blank key (you must have at least one working key for this procedure).

The PAT

1. Make sure you have both keys.
2. Turn on car but don't start. Watch "theft" indicator untils it goes out.
3. Turn off and repeat procedure with second key.
4. After "theft light goes out, insert new key and turn on.
5. Wait until the theft indicator goes off and then turn off switch.
6. Wait thirty seconds. New key is now programmed into security module. Repeat for any other keys.


1. Erase any old codes by entering the factory code.(buttons will light up)
2. Press 1/2 button within 5 seconds.
3. Press 7/8 and 9/0 buttons at the same time within 5 seconds.

To set new code:

1. Enter factory code (numbers will light up)
2. Press 1/2 button within 5 seconds.
3. Enter personal 5 digit code(decide beforehand) within 5 seconds of each previous one.
To unlock all the doors,press the 3/4 button within 5 seconds of the driver door unlocking.
To lock all doors and set alarm system,press 7/8 and 9/0 at the same time.
To disarm or reset a triggered alarm,just enter personal or factory code.

Do not set a code with five of the same consecutive numbers. It's too easy for thieves to figure out.

Deactivating and Activating Autolock

To deactivate the "autolock":
With all doors and tailgate closed but NOT locked,and ignition OFF.
1. Enter 5 digit code
2. While holding 7/8 button in, press and release the 3/4 button.
3. Release 7/8 button
The horn will chirp once if the "autolock" was deactivated
or two times if "autolock" was activated.

To reactivate the system,repeat steps 1 thru 3

Alternate Method To Deactivate And Activate Autolock

Do steps [1] through [5] (below) within 30 seconds or you'll have to do it over. If you have to do it over, wait 30 seconds between attempts.
Close all doors securely.

1.Turn the ignition key to ON.

2.Press the power door UNLOCK control THREE times.

3.Turn the ignition key from ON to OFF.

4.Press the power door UNLOCK control THREE times.

5.Turn the ignition key back to ON .The doors should lock and unlock.

6.Press the power door UNLOCK control. The horn should chirp ONCE to confirm successful switching of the autolock system

Troubleshooting:

The engine does not start and LED remains off.
1. Check PATS system fuses
2. If alarm is fitted check if LED functions for alarm: if not check cigar lighter fuse (also used for LED)
3. If not go to main dealer

Engine does not start: LED flashes rapidly Leave ignition on until the LED starts to flash a 2 digit code: (sequence- pause-sequence)
Check the following codes:
Code flashes:
1:3 Key code not received. Is key screened by other keys or objects? Try different key: if okay then first key is faulty. If not go to main dealer
1:4 Partial code only received. Try again. If not okay use different key. If not go to main dealer
1:5 Key not programmed into PATS. Program key as above using master
1:6 Faulty link between PATS module and EECV Go to dealer .

Is there an ALDL port on a legend ...to plug in a scan tool


There is a connector but it is not like the connector used in the newer 1996 OBD2 cars, your year uses OBD1, here is how you check for codes in this car.

Acura OBD1 Codes Retrieval
Acura vehicles 1986-95 obd1 code retrieval
There are a few different ways to retrieve the codes for "check engine light" for Acura vehicles. One method is to use a led light (sometimes 2 led lights) on the computer or controller box itself. If it has 2 led lights, the color is red and amber. The red is used for flashing the codes whereas the amber is used for adjustment. If you have only a single led light indicator, then that is used for flashing the code.
The controller box can be found by lifting the carpet of the passenger side front foot well or floorboard. You can see the led lights without removing the controller. On other models, you can find the controller under the driver or passenger front seat.
The second way to get the code is using a jumper wire on the diagnostic connector located on the kick panel at the front passenger side. You then watch the codes being flashed at the dash panel after you turn the key on. To read the code being flashed is easy. Example: Code 23 is 2 long flashes followed by 3 short flashes. A longer pause separates the next code that follows.
Here are Acura vehicles 1986-95 general codes:
Code 0 Electronic control unit (ecu)
Code 1 02 (oxygen) sensor
Code 3 and 5 map sensor
Code 4 Crank angle sensor
Code 6 Coolant temperature sensor
Code 7 Throttle angle sensor
Code 8 Crank angle sensor (TDC)
Code 9 Crank angle sensor (CLY)
Code 10 Intake air temperature sensor
Code 12 EGR system fault
Code 13 Atmospheric pressure sensor
Code 14 Electronic air control valve
Code 15 Ignition output signal
Code 16 Fuel injector fault

1999 1500 Chevy Silverado - microchip for anti-theft?


Document ID# 803013
1999 Chevrolet Chevy K Silverado - 4WD

Security Lamp Illuminated on the IP, Engine Stalls, No Start, DTC B2960 (Security System Sensor Data Incorrect but Valid) Set (Inspect and Repair Cause of DTC B2960)
1999-2001 Chevrolet and GMC C/K Pickup and Utility Models (Silverado, Sierra, Tahoe, Suburban, Yukon, Yukon XL)

This bulletin is being revised to add information on inspecting for electrical intermittent conditions and important connector C201 tightening steps. Please discard Corporate Bulletin Number 01-08-56-002 (Section 08 -- Body and Accessories).

Condition
Some customers may comment on the following conditions. These symptoms may be intermittent.

• Security lamp illuminates while driving. The Security lamp may be On or Off when the customer brings the vehicle to the service facility.

• The engine cranks but will not start and the Security lamp is flashing.

• The engine starts then stalls and the Security lamp is flashing.

Cause
Condition(s) may be due to an incorrect Passlock™ sensor voltage received by the body control module (BCM) from the Passlock™ sensor due to the following conditions. Most intermittent conditions are caused by faulty electrical connections or wiring.

• A 7 ohm variation in the sensor ground circuit wiring, circuit 1057

• A 100 ohm variation in the Passlock™ sensor signal wiring circuit, circuit 1836

Inspect for the following items:

• Broken wiring inside the insulation.

• A poor connection between the male and female terminal at the connector. Refer to Testing for Proper Terminal Contact under Testing for Intermittent and Poor Connections in Wiring Systems for the specific procedure.

• A poor terminal to wire connection. Some conditions that fall under this description include poor crimps, poor solder joints, crimping over the wire insulation instead of the wire itself, and corrosion in the wire to terminal contact area.

• Wire insulation that is rubbed through. This causes an intermittent short as the bare area touches other wiring or parts of the vehicle.

• A poor connection between the male and female terminal at a connector. This poor connection may be the result of contamination or deformation.

- Contamination may be caused by the connector halves being improperly connected. A missing or damaged connector seal, damage to the connector itself, or exposing the terminals to moisture and dirt can also cause contamination. Contamination, usually in the underhood or underbody connectors, leads to terminal corrosion, causing an open circuit or intermittently open circuit.

• Separate the connector halves.

• Visually inspect the connector halves for contamination. Contamination may result in a white or green build-up within the connector body or between terminals. This causes high terminal resistance, intermittent contact, or an open circuit. An underhood or underbody connector that shows signs of contamination should be replaced in its entirety including the terminals, the seals, and the connector body.

- Deformation is caused by probing the mating side of a connector terminal without the proper adapter, improperly joining the connector halves, or repeatedly separating and joining the connector halves. Deformation, usually to the female terminal connector tang, can result in poor terminal contact causing an open or intermittently open circuit. Using an equivalent male terminal from the J 38125-B, test that the retention force is significantly different between an good terminal and a suspect terminal. Replace the female terminal in question.

Correction
Have any of the following components had service recently?

• The BCM

• The ignition lock cylinder case assembly

• The PCM/VCM

If any of the above components have been replaced, the Programming Theft Deterrent System Components procedure must be performed before any diagnostic procedures are performed.

To assist in diagnosis, the following steps are provided.

Does the engine start? If not, use the Engine Cranks but Does Not Run diagnostic information in the Engine Controls sub-section of the applicable Service Manual.
Important:

• The Security telltale on the message center is controlled by the vehicle theft deterrent (VTD) system and the content theft deterrent (CTD) system. The Security telltale is controlled by the BCM through the Class 2 data line.

• The VTD system portion of the BCM controls the Security telltale when the ignition switch is in the On position. The VTD system uses the Security telltale as a malfunction indicator.

• The CTD system portion of the BCM controls the Security telltale when the ignition switch is in the Off position. The CTD system uses the Security telltale to identify system status.


Observe the Security indicator lamp in the instrument panel.
Remove the key from the lock cylinder.
- Security indicator should be Flashing when the door is open.

- Security indicator should be Off when all the doors are closed.

- If the Security indicator does not come On or go Off correctly, refer to the Content Theft Deterrent System diagnostic and repair information in the applicable Service Manual.

With the Doors closed, place the key in the lock cylinder and turn to the Run position. Observe the Security indicator lamp.
- Lamp is On and does not go Off however, the engine starts. This indicates that the VTD system detected a fault when the engine was running.

- Lamp flashes On and Off. This indicates a problem has been detected by the VTD (Passlock™) system and the engine may not start this key cycle, a current condition.

Important: You must diagnose the diagnostic trouble codes (DTCs) in the order specified in the DTC table shown below. Failure to do so may result in one or more of the following conditions:


• Extended diagnostic time

• Incorrect diagnosis

• Incorrect parts replacement

Important: Before you use this table, diagnose P0601, P0602, P0604, and P0606. Refer to Diagnostic System Check - Theft Deterrent.

PXXXX Other PCM DTCs

Refer to the following procedures:

• Diagnostic System Check - Engine Controls in Engine Controls - 4.3L

• Diagnostic System Check - Engine Controls in Engine Controls - 4.8L, 5.3L, 6.0

• DTC P0192 in Engine Controls - 6.6L

• Diagnostic System Check - Engine Controls in Engine Controls - 8.1L


If none of the above items are true, proceed with the following steps:

Install seat covers.
Connect the scan tool to the diagnostic link connector (DLC).
Enter scan tool diagnostics.
Select the model year of the vehicle.
Select light truck.
Select F1, (Body).
Select "C" or "K" for Series.
Select F0, Body Control Module.
Select F0, (Diagnostic Trouble Codes (DTC)).
Select F0, (DTC information).
Select F0, (Current DTC).
Record on the repair order any current DTCs displayed. If none, skip the next step.
Is a current B2960 DTC displayed? If no, the condition is not present with this key cycle. Continue to the next step.
Select Exit.
Select F1, (History DTC).
Are any history DTCs other than B2960 present? If so, diagnose those DTCs first using the appropriate service information, otherwise continue.
Select Exit.
Select Exit.
Select F1, Data Display.
Select F6, Security.
Cycle the key to the OFF position and wait 20 seconds.
Slowly turn the key to the RUN position. Be careful not to turn the key into the START position.
Observe the following values:
- Passlock™ Data Voltage should be 5.0 volts.

- Passlock™ State should be Normal.

- Passlock™ Code should be Open.

Rotate the key to the START position, and observe the following again:
- Passlock™ Data Voltage should be less than 5.0 volts. Passlock™ Data Voltage should remain steady and not fluctuate. The test vehicle used for this diagnostic procedure had a voltage value of 2.49 volts. The vehicle being worked on may be either higher or lower than this value. The key is that it has to be less than 5.0 volts.

- Passlock™ State should be "Monitor Passlock™".

- Passlock™ Code should be Valid Code.

If no trouble is found and the customer has experienced one of the symptoms or the code is a history DTC, the most likely cause is the VTD (Passlock™) wiring, specifically the wires from the VTD (Passlock™) sensor to the BCM.
