SOURCE: how do you reset the anti theft system

Try disconnecting your battery cables then wait about 10 minutes. The computer should reset itself. Reconnect the wires to the battery. It is normal for the theft light to blink about every 5 seconds when the ignition key is out or in the off position. This means the system is armed and working properly. Hope this helps. God bless!

SOURCE: 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


DTC
Diagnostic Procedure
Module

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.
