Default SCFAQ: Airbag Warning Light Reset

Info Provided by Rich @ http://www.intellexual.net/faq.html#00


Airbag Warning Light:
info provided by VQT:

WARNING: this manual fix should only be attempted if you are absolutely certain that the airbag warning light was tripped by a code 22 error. A code 22 error occurs when the ignition is powered up without the gauge cluster plugged into the wiring harness (starting the car without the gauge cluster in place). The brain runs a diagnostic check and does not receive feedback from the airbag, causing a fault. If this is not the reason your airbag warning light is on, then it is strongly recommended that you do not perform this fix. Take your car to a dealership or service center to be diagnosed and properly fixed; there could be a real and major problem with your airbag system.

First, you need to know the trouble code. Locate either of the two diagnositic ports in your car. One if attached to the engine block, and the other is underneath the driver dash by the auxiliary fuse box. There should be a black plastic cover labelled 'Diagnostic' or 'DLC2'. The following procedure must be performed perfectly in order to work...

STEP 1: Turn the ignition on for approximately 20 seconds, but do not start the engine.

STEP 2: Stick a wire or paper clip in the Tc & E1 pinholes of the DLC2.

STEP 3: If the light blinks continuosly or code 22 (two fast blinks, a pause, then two more fast blinks), then you can probably manually cancel the warning light. If it is any other code, you need to trouble shoot it and fix the problem.

STEP 4: To clear the code connect two wires to Tc and AB of the DLC2.

STEP 5: Turn the ignition to ACC or ON and wait approximately 6 seconds.

STEP 6: Start with the Tc terminal and apply a wire to body ground alternately to Tc and AB twice each in cycles of 0.5 - 1.0 seconds.

STEP 7: Finally keep Tc to ground. If the clearing is done properly, then the airbag light will blink in 50 msec incriments continously. If it did not, then you didn't ground the Tc and AB properly. Repeat the process. The procedure may take between 3 to 15 attempts to work.

this is the part i don't understand- explain it to me as if i'm a kid....
STEP 6: Start with the Tc terminal and apply a wire to body ground alternately to Tc and AB twice each in cycles of 0.5 - 1.0 seconds.

LoL, i just did this. Its not necessarily how quick you do it, but staying very even in your timing, as in the time between each contacting wire, even when switching wires must all be equal. Do the switching double tap in sets of 3. If you double tapped right on Tc the airbag light will go off, quickly move to Ab and double tap, this will make the light go of longer if you did it right. If it stays off you did it right, if you didnt it will come back on. If the light comes right back on in either situation, change your timing.

Touch them individually twice starting with Tc:
Tc-Tc-Ab-Ab-Tc-Tc-Ab-Ab-Tc-Tc-Ab-Ab

Like i said before, if after doing Tc-Tc or Ab-Ab the light comes immediately back on you didnt time properly, so slow down or speed up.

Its not going to be VERY fast, the timing should be just how long it takes for you to move the ground wire between the two.

Just make sure to be CONSTANT in the timing, the longer the light stays off the closer you are.

LoL, well this explanitory knowledge is coming from it having taken me 40 tries to make the light go off. Trust me, by the time i figured it out, i was a pro, i shoulda made the light trigger again so i could turn it off again!!

I ain't saying you should do this because..... I can't, but the light does not complete the circuit so the bag will function with or without the light locked in place........... Consider how many times I've pulled the cluster in my car..... I have no bulb.
