Airbag Light Reset Procedure?

Has anyone had experience resetting the SRS airbag light using the grounding procedure in the Camry manual (pg RS-65)? Does it work? What precautions are needed? I've read a couple threads where guys have had problems with it. I removed the airbag to change a headlight/parking light switch on the steering column IAW the manual. Now I've got the light. Toyota wants $112 to reset it. Help!
94 Camry

I copied this from another forum a while back (they're referring to the DLC1 - data link connector under the hood):

Use two short grounding wires, one at TC and one at AB, then

I approximated the time between grounding TC AND AB (roughly .5 to 1 sec) and
then held Tc to ground and the light flashed continously..I removed the ground
from TC and Voila' problem solved.I took me two tries....not too bad.Thanks Alot.

Hot dam! It worked the first time! Anytime I keep my money in my wallet is a great day! I already had the procedure from the "Camry Maintenance Manual" posted at the top of the website. The trouble was I read several other posts on this site and others about guys having trouble getting it to work. I found someone who said it does work in you Dan. If I could, I would buy you a beer. Thanks! For anyone else trying this make sure you use a good grounding point. That may be where others are having trouble. I wire brushed the engine removal hook near the DLC1 diagnosis connector and used it for my ground. Thanks again Dan and thanks to whoever loaded the manual on the site. My Haynes manual is in the garbage.

Hey AF'ers,

I have a 92 Camry V6 with Airbag light on. I tried the procedure listed in both this thread and the "94" manual. Is the process, or test procedure different in the "92"s? My light went on after troubleshooting a no start problem, I had removed the negative battery terminal for quite some time, and I had the ECU shutdown.

Thanks

Here's the official Toyota way of clearing the warning light for '92-'96 Camrys:

It is very similar to what Daniel posted with minor differences. The final grounding of tc is held for as long as necessary, and the interval is not more than 0.2 sec between terminals.

I will post this in the FAQ thread. Thanks Daniel.

Would anyone tell me exactly where the DLC's are located on my 93 four cylinder Camry? How big are they? What shape? Any label on them? I have the same problem but can't find the box. Thanks.

I don't believe you have any of the correct type. Your car is OBDI compliant. The DLCs in question are OBDII connectors.

The posts on this topic might be old but they are still praise-worthy! I had to pull the dash on my 95 Cam to repair the AC. After reassembly the SRS ligh stayed on constantly. This was the perfect fix! Thanks AF! I find it interesting that none of the manuals (Haynes) mention this little issue.

Thanks a million Daniel
Worked like a charm

Although this thread is quite old, it's still very Valid. For other vehicle reset procedures here's a site that will explain everything you need to know about airbag lights and resetting the system. http://www.airbagsolutions.com/

This website gives you the procedure for diagnosing and resetting airbag lights. See if your car is listed here. Although it’s a pay site ($14.95/day), it’s a lot cheaper than going to the dealer
http://www.airbagsolutions.com/vehicles_list.aspx

On most vehicles, the airbag light should come on for @6 seconds, and then go off if the system is working properly. If there is a fault or a problem in the system, the light will remain illuminated, or flash continuously. If the airbag light does not work properly, some vehicles have an audible tone that sounds indicating a problem with the airbag light system. When the light is on (or the tone is sounding), the airbag will NOT deploy, even in an accident.
The flashing light on your car is telling the answer you need. On some vehicles, the light is flashing a two digit code. Once you know the code, you can most likely repair it yourself. There are fairly easy procedures that most people are capable of repairing.
Airbagsolutions.com has the fault code charts to tell you what is wrong and how to fix it!

Some vehicle manufacturers accommodate systems without a scanner (like Toyota, Lexus, Nissan, Infinity, Honda, Acura, Ford, Lincoln, Mazda & Mercury) and some require a scan tool.

This was very useful. It took me a while to get it, but it worked. The key is to ground the wires one after the other, just like it specifies..... Thanks for your help.....:)

I have a 92 Camry, it took lots of attemps, I finally did it, by grounding TC then AB alternately -like instructions say, I did it quickly like .2 seconds back and forth and then it worked. When I did it slower (about 1 second) = no luck. Hope it helps you!

It really helped with my 1993 camry. My car's airbag light goes off after starts. I grounded each of TC and AB in 0.2 seconds for five times. One second didn't work with my car.

I have a related problem: In our 1992 Camry we discharged the battery completely (we'd left the ignition on over night...) After jump-starting the car, the airbag light went on and will not shut off.

I've tried the reset procedure described above and also checked in the Toyota manual. I must have had 30+ trials with various time intervals etc and the light stays on. After doing a diagnosis I get error code 14 back.

Does anybody have any idea what to do from here besides going to a dealership?

Thanks in advance, Christof

FYI: Code 14 means and IGF signal is not getting from your ignitor to your ECM. This is either a bad connection in the wiring, bad wiring, or bad ignitor. I don't know what this has to do with your airbag light.

If you totally discharged your battery, it is time for a new one. Perhaps your battery or your alternator are bad as a result of your discharging/charging cycle. Have them tested. Bad alternators can create really strange symptoms on your dash lights.

!!! PROBLEM SOLVED !!! Here is what I changed from the procedure described above:


I used the DLC 2 connector which is located near the break paddle. (It is NOT behind the coin box which is only true for later (1994?) models.) Yesterday, when I wrote my frustrated email above, I had been using DLC 1 which is under the hood.
I used a jumper cable from the minus pole of the battery to make the ground contact with the Tc and AB terminals of the DLC 2 connector. (Previously I had grounded the cables to the top of the engine block at a location which I had cleared with a file.) The jumper cable and the DLC2 was actually quite convenient as I could sit in the driver seat and directly observe the airbag light.

"Unfortunately" I do not know which of the 2 modifications did the trick since the airbag / SRS light cleared with the first trial! As other people have commented, I did not stick to the 1sec intervals specified by Toyota but did the Tc-AB-Tc-AB-TC sequence fairly quickly. (Now that I think about it: perhaps I just got incredible lucky by using the correct timing intervals. I doubt it somewhat though, because I had tried it dozens of times the day before to no avail.)



Cheers, Christof

Hey there, I've got a 92 Camry and I recently got a mechanical inspection to register it in a new province. One of the things they failed me on was the fact that my airbag light would not come on at all (when the keys are first in the ignition and all utility lights comes on, it does not.)

does anybody have an idea of what is the issue here? would a an airbag light reset procedure cure this issue?

No, there is a problem with the circuit.
Check the SRS Fuse (ECU-B fuse, Junction Box No. 2 - Next to the battery)
Check the SRS warning light circuit
Check terminal LA of the center airbag sensor assembly and the electrical connection check mechanism. If normal, replace the center airbag sensor assembly.
May be the bulb, but it may be difficult to get to.

So I've checked the ECU-B fuse - and it seems fine. Even replaced it just in case I couldn't visually locate the problem, and there is still no difference.

I've just downloaded a circuit diagram for my vehicle, and may try to check out the whole SRS system, but it seems very complicated to check every connection point. Going to attempt today to remove the centre console and visually inspect the center airbag sensor assembly like you suggested and check the LA terminal.

However in the mean time here is something to chew on - I tried to jump the TC & E1 terminals in my diagnostic plug under the steering column to get a diagnostic code. The airbag sensor light still did not light up to give a diagnostic code, but the "cruise" light began a continuous regular blink. This continuous blink (if it was the airbag light) would mean there is a voltage drop, which would either mean there is a problem with the battery or the center airbag sensor assembly.

Related to this voltage drop I read that the voltage between the terminals E1 & TC should be equal to the voltage between the two battery terminals. When the the key position is turned to "on" the battery voltage is 8.6 (i've drained it quite a bit in the past 2 days) and the voltage between E1 & Tc is only 5.9 5.7 or so there is definitely a voltage drop going on.. possibly another indicator there is a problem with the center airbag sensor assembly?

Before you try and diagnose anything further, get the battery voltage up where it should be.

So I opened up the center console to take a look at the sensor and found it had been completely disconnected. I reconnected it and now the light is always illuminated - whoever owned it before me disconnected it so the light would go off. Time to re-read the above procedures and hopefully get that light off.

Hi everyone,

I have the 1992 Toyota Camry V6 LE model. I have the same issue regarding to the AIRBAG light in my dashboard ever since I changed the D transmission light bulb couple of days ago in my dashboard since it was burned out. Once I was finished my AIRBAG warning light turned on. I did a diagnostic flashing a 41 code. I read here to clear that code I need to go to the DLC 1 or DLC 2 putting two separate grounding wires in TC and AB then alternate back and forth grounding TC for ten seconds so my warning light could flash constantly, resulting the error code to be deleted. However, I am not sure which is a good source of grounding wire because I used two paperclips and small alligator clips that are negative and positive but it did not work. Can you guys provide me links for a good grounding wire or tell me a different way I can do this that is more simple way to clear this error code in step by step?

By the way here is what I used in the picture to troubleshoot the error code.

Thank you so much.
