3rd Generation Airbag light wont turn off

I've just bought a 93 Camry wagon, and the airbag light will not turn off.

The previous owner said it occurred when they took it to a shop and they put in a new battery.

It is a code 41, basically, "There was a stored code"

I have done the code reset as shown here: http://i16.photobucket.com/albums/b8...irBagReset.jpg

I have tried a few times but the code will not go away, it keeps coming back as soon as I turn the key back to "on."

I need the light to be off so I can take the car in for MD inspection, otherwise I would not care.

Any help is appreciated, thanks in advance

If you need the light off...just unplug the module. Work on it after the fact...most inspectors don't look fer the airbag light to come on and go off.

It's all in timing...really. Are you sure yer gitting a good ground when you hook up yer shorting wires? That's a common problem when people are doing this.

Just unhook the battery for like 10 minutes and that will erase it. Shouldn't come back for a while (50 miles maybe)

Just do it in the parking lot before you get it inspected haha. I've done it before, works perfectly

BamZip: Just unplugging the module will cause the light to go out? Where is it? I'm used to cars where if you pull the bulb out the SRS system makes all kinds of noises I know I'm doing it right because I can watch the airbag light go off when I do it. This sounds like a good option if just disconnecting it will work.

Chris: I'll try that this afternoon!

Thanks to you both for the replies.

Just pull out the SRS fuse, then the light will be turned off.

Or

Do the code reset procedure again.
But this time use the jump cable directly connect the battery negative as the "Body Ground".

Good luck.

When I did my 1998 T-100, it didn't want to clear either after many tries using both the body ground and battery negative post. So after I held the last ground down (Tc) and waited fer the signal to appear...I turned the ignition off and walked away fer about 20 min. Turned the ignition back on and it was all clear. WHEW!!

On my truck, the center module controls everything. So if it's unplugged...no ABS light or warning will appear. Unless the inspector is looking fer the airbag/SRS symbol to light up and then go out...it should pass without any probs until you can git yer timing right.

Not sure what else is hooked up on that fuse fer the Camry. I know on my T-100...the combo meter is also hooked up to that fuse. It's best that you look up the wiring diagram and see what else would be affected if you pull that fuse.

I believe that the SRS system is separate from the ECU...I know the check engine light can be reset by disconnecting power to the ECU...but I believe that the SRS will retain the error code(s) even if you disconnect power to it. But if it worked fer you...great. I know it didn't work on mine.

Are you sure the code is "41"? The SRS codes are very basic and I only show 6 codes fer my T-100 and they are numbered 11, 12, 13, 14, 15, 31 with the SRS light on. Could you post up where you got yer codes from?

Did you check all the wiring and sensors fer problems? Since it's been on since you got it...there's no guarantee that there isn't something seriously wrong with the SRS. On my latest T-100 purchase I found the steering air bag had deployed and they ripped the guts out and fiberglassed the back of the pad to make it appear that it was still good. I ended up buying a used pad fer about $150 shipped.

If you do take a peek at the center bag, make sure you unhook the battery fer at least a minute before you attempt to work on it. It should be just a few Torx screws that hold it on

Doing some searching in this forum I found this...

Seems there isn't a code 41...

Are you sure that's for my car?

I know it's a 41, I'm using a snap-on MT2500 with the Asian imports cartage. To make sure the unit was not malfunctioning, I watched the diag lights flash and all - confirmed code 41. That's also how I know my timing is correct

The 93 Camry spec sheet I found (I can't find it again . . . doh) confirmed the tester's analysis - that it's the code 41 is for "A code is stored" - from all the reading I've done that is the code that pops up when the airbag is replaced or the battery is messed with.

I haven't had a chance to pull the terminal yet, I hope to do that when I get home today.

I agree with BamZipPow...disconnecting the battery has not worked for me. My dumb airbag light stays ON all the time :-(

The SRS code has to come from the diagnostic port in the engine bay.

Tc and E1 needs to be shorted together to read the code.
Tc and AB are used to clear the code.

Not sure how the Snap-On MT2500 Asian Import cartridge works...

Right, disconnecting the battery did not work. I tried it last night.

Does anyone know where I can find a wiring diagram, or an online copy of the factory service manual?
I want to just cut the airbag light wire, and if it makes noise I'll put a resistor on it.

BamZip:

The MT2500 is an OBD1 and OBD2 scan tool with specific manufacturer data loaded in it. It shorts the TC and E1 to read the code, then reads it and checks it against its internal database of codes provided by Toyota.

Then when I tell it to, it will short TC and AB in the procedure required, and flash the on-board diagnostic lights as it is doing it.

The expensive part of the MT2500 is all the random manufacturer specific OBD1 diagnostic plug adapters.

It's basically this thing - http://www.denlorstools.com/home/dt1...rogrammab.html
