If you are doing the on-board diagnsostic scan, there isn't a way of checking what test it is running. If you use an obd 2 scanner, then it will show an entire list of which scans are being performed

Air Bag Deployment Circuit Drop in Battery Voltage

Circuit Description

Normal Operation

The diagnostic monitor measures the voltage at pin 13 of the diagnostic monitor connector. Voltage at pin 13 should be equal to battery voltage. If the voltage measured at pin 13 drops to less than 9 volts, the diagnostic monitor will flash out code 12.

Possible Causes

A drop in battery voltage at diagnostic monitor pin 13 can be caused by:

1.An open circuit that would prevent battery voltage from reaching diagnostic monitor pin 13.

If the instrument panel fuse and/or the power distribution fuse are blown, be sure to diagnose the system for possible causes 2 and 3 below.

2.A short to ground in Circuit 611 (W/O) or 612 (P/O) may result in a blown instrument panel fuse and/or power distribution fuse.

3.An internal short to ground within the safing sensor may result in a blown instrument panel fuse and/or power distribution fuse.

4.A problem in the charging system causing battery voltage to drop below 9 volts.

How do i fix my 1997 mercury grand marquis my air bag light flashs code 41

B1941 41 RH primary crash sensor feed/return circuit open GO to DTC B1941.

Normal Operation
The voltage at Pin C276-16, Circuit 617 (PK/O) is set by the air bag diagnostic monitor to be slightly less than battery voltage. Circuit 617 (PK/O) is connected to Circuit 624 (Y/W) inside RH primary crash sensor. Therefore, the voltage at Circuit 624 (Y/W) and air bag diagnostic monitor Pin C277-24 should be the same as the voltage at air bag diagnostic monitor Pin C276-16, Circuit 617 (PK/O).
The air bag diagnostic monitor periodically pulls the voltage at Pin C276-16, Circuit 617 (PK/O) low to verify the connection to Pin C277-24, Circuit 624 (Y/W). If the voltage at Pin C277-24, Circuit 624 (Y/W) does not pull low as a result of this test, the air bag diagnostic monitor will store in memory DTC B1941 and flash lamp fault code 41 on the AIR BAG indicator. If the connection between Pins C276-16, Circuit 617 (PK/O) and C277-24, Circuit 624 (Y/W) is later serviced, DTC B1941 will be stored in memory.
Possible Causes
Failure to get low voltage at Pin C277-24, Circuit 624 (Y/W) during the test can be caused by:
  • an open circuit in the wiring harness in either Circuit 617 (PK/O) or Circuit 624 (Y/W).
  • an open circuit inside RH primary crash sensor across Circuit 617 (PK/O) or Circuit 624 (Y/W).
  • a short to battery or ignition voltage in any of the Circuits 617 (PK/O), 619 (PK/W), 624 (Y/W), 625 (Y/LG).

What do codes P0411, P1000

P1000 code means the codes were cleared or the battery was disconnected
Powertrain Control Module (PCM) Reset Description All OBDII scan tools support the powertrain control module (PCM) reset.
The PCM Reset allows the scan tool to command the PCM to clear all emission-related diagnostic information. When resetting the PCM, a DTC P1000 will be stored in the PCM until all the OBD II system monitors or components have been tested to satisfy a drive cycle, without any other faults occurring. For more information about a drive cycle, refer to Drive Cycles .
The following events occur when a PCM reset is performed:
  • Clears the number of Diagnostic Trouble Codes (DTCs).
  • Clears the DTCs.
  • Clears the freeze frame data.
  • Clears diagnostic monitoring test results.
  • Resets status of the OBD II system monitors.
  • Sets DTC P1000.

P0411 Secondary Air Injection System Incorrect Flow Detected

neither of these could cause a no start or no crank problem . Is the battery good an do you have good connections on the battery ? Do the headlamps show bright when on ?

What is the location of fuse for speedometer on 2o04 ford explorer

Speedometer The instrument cluster receives the vehicle speed sensor (VSS) signal from the powertrain control module (PCM) through the standard corporate protocol (SCP) communication network. The instrument cluster monitors the VSS input from the PCM and commands the speedometer with a corresponding movement of the pointer.
  • The speedometer/odometer is inoperative
  • Circuitry.
  • Powertrain control module (PCM).
  • Instrument cluster.
  • Go To Pinpoint Test L .
  • Use the recorded instrument cluster DTCs from the continuous and on-demand self-tests.
  • Are any instrument cluster DTCs recorded?
If instrument cluster U1123 is retrieved, REFER to Powertrain Control/Emissions Diagnosis (PC/ED) manual to continue diagnosis.

For all other instrument cluster DTCs, REFER to the Instrument Cluster Diagnostic Trouble Code (DTC) Index.

For inoperative speedometer, GO to L2 .

  • Connect the diagnostic tool.
  • Key in ON position.
  • Enter the following diagnostic mode on the diagnostic tool: Instrument Cluster Active Command.
  • Select the instrument cluster speedometer active command.
  • Trigger the speedometer and scroll in increments of 10% while monitoring the speedometer. The speedometer should increase in increments of approximately 20 km/h (12 mph) for each 10% change.
  • Does the speedometer increase within specifications?
REFER to Powertrain Control/Emissions Diagnosis (PC/ED) manual to continue diagnosis.

  • Key in ON position.
  • Monitor the compass, air temperature and message center functions of the integrated circuit display.
  • Do the compass, air temperature or message center displays operate correctly?
GO to L4 .

  • Disconnect all instrument cluster connectors.
  • Check for:
    • corrosion
    • pushed-out pins
  • Connect all instrument cluster connectors and make sure they seat correctly.
  • Operate the system and verify the concern is still present.
  • Is the concern still present?
INSTALL a new instrument cluster. REFER to Instrument Cluster in this section. TEST the system for normal operation.

The system is operating correctly at this time. The concern may have been caused by a loose or corroded connector. CLEAR the DTCs. REPEAT the self-test. There isn't a fuse just for the speedometer , there are four fuse for the whole instrument cluster . If one of these fuse's were burnt you would have more then just the speedometer not working ! You need to have a scan tool to find out what is up ! you could need a new cluster ! Is the check engine light on ? if not wouldn't think vehicle speed sensor bad , besides speed info for speedometer PCM uses for transmission shift points ! Good luck ,hope this helps !

I can't get an inspection sticker for my car because it keeps failing inspection because the computer will not reset. Every time it does the same thing. When they test the OBDII Readiness it says the...

Every time you reset the light or disconnect the battery it completely resets the system and it has to go through EVERY test again. The O2, EVAP, and Cat tests are generally the LAST THREE tests that are tested. You're not doing yourself any favors here.

Essentially what these readiness monitors are is the computer's notation that his has run the self diagnostics on each system and that the results feel into the expected results. If it is outside the expected results the computer will generally try to run the test multiple times before setting a DTC and turning on the Check Engine Light. It cannot set the status to "Ready" until it has a successful test within expected results; sometimes multiple successful tests. Sometimes, the tests need to run at different speeds - so the vehicle has to be driven not only at freeway speeds, but also city speeds for the tests to complete properly.

The O2 test MUST complete before the Catalyst test can run. The EVAP test generally requires that you have your fuel level at between 1/4 and 3/4 and that the vehicle sit undisturbed after being driven for a period of time for no less than 8 hours in order to run the EVAP test.

The same can be said for the O2 test sometimes because the computer needs to test the O2 sensors reaction to heating up and cooling down. Eventually they will all complete - unless there is an issue. I have seen where a component was in the process of going out and the computer was getting both GOOD and BAD results when running the tests. As a result it wouldn't set ready status because it wasn't getting the concurrent GOOD test results.

As a Texas Recognized Emissions Repair Facility - my shop sees this kind of stuff all the time.

Good Luck.

Are the any trouble codes being activated from this occurring?

And can you monitor the fuel rail pressure with it faulting? All you need is an obd reader to do this.

Could be a whole range of problems, but it is most likely a fuel pressure fault.

Do you service the vehicle yourself, the stored and self learned parameters for the high presure fuel pump need to be reset evey time after you change the fuel filter, or it will have incorrect values.

To clear the codes from your ECM do as follows;

Set Diagnostic Test Mode II (Self-diagnostic Results)

1. Confirm that accelerator pedal is fully released, turn ignition switch ON and wait 3 seconds.
2. Repeat the following procedure quickly five times within 5 seconds.
a. Fully depress the accelerator pedal.
b. Fully release the accelerator pedal.
3. Wait 7 seconds, fully depress the accelerator pedal and keep it for approx. 10 seconds until the MIl starts
4. Fully release the accelerator pedal.
ECM has entered to Diagnostic Test Mode II (Self-diagnostic results).

To Erase Diagnostic Test Mode II (Self-diagnostic Results)

1. Set ECM in Diagnostic Test Mode II (Self-diagnostic results).
Mode II (Self-diagnostic Results)" .
2. Fully depress the accelerator pedal and keep it for more than 10 seconds.
The emission-related diagnostic information has been erased from the backup memory in the ECM.
3. Fully release the accelerator pedal, and confirm the DTC 0000 is displayed.

Or in short
Ign on count to 3
full on and off throttle 5 times within 5 sec's
count to 7 hold throttle down for 10 or so seconds
wait for the ECM light to flash let go of throttle and your in count the codes after you have written them down or fell you don’t need any codes just hold the throttle down until you see the ECM pattern change to ten fast flashes twice and then ten slow flashes and there you have one reset ECM

Hope this gets you somewhere.

Airbag light on. flashing 5 times 2 times then stays on

I think you have a false code stored due to your work. clear the code and you should be ok.
If the air bag indicator does not illuminate or the indicator stays on or flashes at any time, a fault has been detected by the air bag diagnostic monitor.
Diagnostic trouble codes (DTCs) may not be displayed for approximately 30 seconds after the ignition switch is placed in the RUN position. This is the amount of time the air bag diagnostic monitor requires to perform all tests and verify system faults.
Each DTC (a series of flashes and pauses of the air bag indicator):
  • Represents a two-digit number.
  • Is always displayed at least twice.
If the diagnostic monitor detects a fault in the air bag system, a diagnostic trouble code (DTC) will be written to the diagnostic monitor's Non-Volatile RAM (NVRAM). This DTC will then cause the lamp to flash a lamp fault code (LFC) on the air bag warning lamp and can be retrieved with the New Generation STAR (NGS) tester. After servicing the DTC may then be cleared from the NVRAM.
If a system fault is present and the air bag indicator is malfunctioning, an audible tone will be heard. The tone is a series of five sets of five beeps. If the tone is heard, the air bag system needs attention.
If a fault exists that makes unwanted air bag deployment possible, the air bag diagnostic monitor will attempt to remove deployment power by turning on a solid state switch to blow the 10A battery fuse.

If the 10A battery fuse has successfully been blown by the air bag diagnostic monitor, the air bag diagnostic monitor will not attempt to blow it again until the proper fault has been repaired and cleared (refer to Diagnostic Instructions). The air bag diagnostic monitor will store both the unwanted deployment diagnostic trouble code and the loss of deployment power diagnostic trouble code. The loss of deployment power diagnostic trouble code is the highest priority.
If a fault exists that makes unwanted air bag deployment possible, the air bag diagnostic monitor has an internal fuse that that will blow (open) automatically. This removes all power to the air bag deployment circuit.
DTCs are prioritized numerically. If two or more faults occur at the same time, the fault having the highest priority will be displayed first. After that fault has been corrected, the next highest priority fault will be displayed.
The air bag diagnostic monitor includes an internal backup power supply. This feature provides sufficient backup power to deploy the air bag in the event the battery (10655) or battery cables are damaged in a collision before safing and air bag sensors close. The backup power supply will deplete its stored energy approximately one minute after the positive battery cable is disconnected.
Once a DTC is logged into the air bag diagnostic monitor memory, it will stay in memory until 80 key cycles have been recorded or until the NGS is used to erase the DTCs. Once 256 key cycles have been recorded since the concern was last detected, the DTC will automatically be removed from memory.
Active Command Modes
This command allows the technician to verify operation of the air bag system, indicator and tone. When the air bag output command is executed, the indicator and the tone are simultaneously activated for approximately four seconds. Both devices are automatically deactivated.

Emissions test

Most of the Smog testers need to use the speedometer for testing since they have to test your vehicle emissions at 15mpg, 25 mph, etc. So you will likely need to get that fixed before your testing
