Hello! Welcome to the site! Thanks for coming! I'm Ron Z. I'm here to provide as much info and insight as I can, to best answer your question.
There is a method to clear the light, and I'll provide it below. However, when the Air Bag light is on, this is a problem in the restraint system. This can be anything from and Impact Sensor, to a problem with the Seat Belts, and anything in between. So it's not a light on because a bag has deplyoed, but it is on because there is a problem (faulty part/sensor) in the system. The best place to start, is to have the diagnostic trouble codes retrieved from the on-board computer. These codes will serve as the starting point for the diagnosis, and will point to the faulty part/sensor. You can then make a more accurate diagnose, and make the correct repair, the first time. There isn't a mechanic on the planet that can look at the light, and say "oh... it's this". Every mechanics first step will be to retrieve those codes. It's just the correct flow of procedure. Some local parts stores, like AutoZone, will read these codes for Free (except in California), but not all will have the appropriate scan-tool. If you cannot find a location that has the appropriate scan-tool to read the codes, you will need to bring it to a shop to have the codes retrieved. Unfortunately, I know this wasn't the answer you were hoping for, but there needs to be a diagnostic process. There is absolutely no way to "guess" at what the problem is, and be correct. And replacing parts at random, based on a "guess", will get frustrating and expensive very quicky.
Here is the procedure to reset the light. If the light returns, there is a faulty part/sensor in the system and we'll need those diagnostic codes to proceed and determine how to fix the problem.
- -Connect the 2 service wires to terminals Tc and AB of DLC 1.
- -Turn the ignition switch to ACC or ON and wait approx. 6 seconds .
- -Starting with the Tc terminal, apply body ground alternately to terminal Tc and terminal AB twice each in cycles of 1.0 seconds . Confirm that body ground is absolute. Finally, keep applying body ground to terminal Tc.
HINT: When alternately grounding terminals Tc and AB, release ground from one terminal and immediately apply it to the other terminal within an interval of 0.2 second . If DTC do not clear, repeat the above procedure until the codes are cleared.
- -Several seconds after performing the clearing procedure, the SRS warning light will blink in a 50 m sec . cycle to indicate the codes have been cleared.
