Reset airbag

Reset airbag.

Since some of you guys here are new owners I thought I'd save you a trip to the dealer once you start modifing your armada's. I'm not sure what set's it off (other than pulling things apart) but at some point you will likely end up with a flashing airbag sensor light. Here is how to reset it yourself.

1. Turn the key from off to on.

2. Watch the airbag light closely. It will stay on for a few secs. and then as soon as it blinks off (the start of the flashing), turn the key off instantly.

3. Count to 5 (1 Mississippi, 2 Mississippi . . . .)

4. Repeat steps 1-3 two more times until you have done the cycle three times.

5. Now turn the key on and watch the light. It will start blinking in a different, slower manner. This is diagnostic mode. You can watch this for a little while, no hurry.

6. Now turn the key off again, Count to 5 like in step 3 again, and turn back on. If the procedure worked, the airbag light will not be flashing.

Because both the search results and the FSM instructions on how to do this aren?t exactly clear, here?s something that I hope is easier to understand.

If your airbag light flashes after 7 secs, then you need to run the airbag diagnostic codes, if your airbag light does not shut off after 7 secs then the airbag ECM needs to be replaced. To run the codes you must enter the first diagnostic mode, from there you can read the number of light flashed to see what the problem is. The second diagnostic mode is meant to show what codes have been cleared, and is not useful for diagnosing problem.

There are 3 modes for the airbag ECM diagnostic unit:

User (Normal)

Present (Diagnostic Mode 1)

Initial (Diagnostic Mode 2)

User (Normal):

This is the mode your car is in when it is not in diagnostic mode, it needs to be left in this mode for proper use of the SRS system, be sure to return the ECM to this mode after completing diagnostics.

Present (Diagnostic Mode 1):

This mode will display the codes causing the error in the SRS system, the number of short flashes of the airbag light corresponds to the error code.

Initial (Diagnostic Mode 2):

This mode is only useful to see what codes have been cleared, it will also show what code is causing the problem.
