How To: Clear Air Bag Light

Ben · 02-23-2009, 03:03 PM

If you have an air bag light on (Code 41) disconnecting the battery or pulling the EFI fuse will not clear the code.

Code 41 Has A Special Way To Clear It:

You Need 2 Separate Wires One For Terminal Tc & One For Terminal AB. You Will Have To Ground Tc For 1 Second Then Switch And Ground AB For 1 Second - 5 Times:

With the key in the ON position:

Ground Tc
...............Remove Ground
Ground AB
...............Remove Ground
Ground Tc
...............Remove Ground
Ground AB
...............Remove Ground
Ground Tc
...............Remove Ground
Ground AB
...............Remove Ground
Ground Tc
...............Remove Ground
Ground AB
...............Remove Ground
Ground Tc
...............HOLD Ground Until Air Bag Light Start To Blink FAST. When The Light Blinks Fast You Are Done.

The timing is tricky. Try doing it at 3/4 second intervals, if unsuccessful try 5/4 second intervals.
It took me about 5 times before I got the interval right.

is the airbag light the srs light?

edit: oops it is the airbag on mines..dont know why i was thinking it was a srs light...lol

Kw8z3boi · 08-29-2009, 01:54 AM

interesting, I'll try to in a few days and give some feedback.

There's no possible way that the air bag would deploy right? LMAO

TomsMR2 · 08-29-2009, 07:10 AM

you need pretty good rhythm, it must be done smoothly and evenly. *most* people dont get it on the first (few) times.

its the toyota approved diagnostic method, its perfectly safe

mr2_kevin · 08-29-2009, 11:46 AM

my ab terminal dont look like theres anything in there. i stuck a wire in there anyways but when i ground it nothing happens. the tc terminal does though and when i ground the tc the airbag flashes. this is on a 3rd gen swap.

mr2boost · 09-01-2009, 06:27 PM

Or just make this & push the button.

Toyota Celica Online: Air Bag Tool

But, Ben's description is the best I have seen yet.

FWIW
IF the air bag light does not reset then you either...
1. Have an aftermarket steering wheel (no more air bag) & just need to pull the ECU-B fuse in the frunk to eliminate the air bag light.
2. Have a problem with the system & you need to pull the code to see what the problem is. Pulling the code is similar to pulling a CEL code & is described in the BGB. Fix problem & then reset the air bag light.

Also, "playing the drums" as this technique has been dubbed or using the Celica Tool I linked to will NOT set off the air bag. If it does then you have a major problem somewhere.

So I'm trying right now. I'm getting Fast blinking from P/S and Cruise.
Airbag is blinking in a cycle
Airbag...Airbag...Airbag...Airbag..............Air bag....... (loops)
Any ideas? doing this wrong? How long is this suppose to take?

Started when i forgot to plug in all the gauge cluster plugs in before turning the car ON.

After some reading on the other forum. I realized that the airbag blinking 4 and 1 time at the end means its code 41. lol ....

I finally got it to work. seems i wasn't go fast enough between the intervals and holding the ground long enough. It wasn't so much a fast blinking airbag light, it was a constant blink (with consistent pauses)

gmplewa · 03-27-2011, 07:18 PM

Pulled my cluster this weekend to remove PO installed white dials. The Air Bag light never came on since I bought my 91 NA last month and now I discovered why, no bulb! I installed a bulb and the Air Bag light came on and stayed on. I wired up an SPDT micro-switch I had lying around NC contact to AB, NO contact to TC and Common to E1. Then it was just a matter of key on then click on, click off until the Air Bag light started blinking fast as Ben said. Much easier than swapping a jumper between terminals. My Air Bag light now only comes on for a few seconds at key on and then goes out, as it should.

Many thanks to Ben for posting the procedure.
