Hello, Great forum and thank you. You guys have help me big time with your picture posts.

I have been reading up on resetting the SRS and its been a little confusing but informative.

I just finished changing my turn signal switch with the help of this forum. But now I keep getting a continuous sold SRS light after the car is started and will stay on. I really need this fixed asap for inspection sticker.

Besides getting the reset tool on Ebay and other way to reset this????

Anyone know a honest (LOL) reliable and inexpensive mechanic in the boston, mass area???

So if 100 people look at my post and know one replies does that mean its a stupid post? Or you don't know the answer?

NOT ONE of you know the answer???

I don't know what reset tool from eBay you are talking about, but the only way I know of to reset the SRS system is with the factory tool. Some independents have one; some subcontract that work to a dealer.

I have changed turn signal switches several times without setting an SRS lamp. Heck, I have removed entire steering columns without setting the SRS lamp. You may have damaged the Spiral Contact or something else. Get somebody to check the system thoroughly.

Honest Mechanic and Boston Mass can't be used at the same time! Try to call Foreign Auto Body in Allston, or Hermes Carriages LTD. in Camb/Belmont. They are two very good restoration shops

Hi,

I know that an SRS module located behind the ashtray can be damaged under certain conditions. I damaged mine by removing the seats and moving the car. It also can be damaged if the steering box is uncoupled and the steering wheel turned.(posted in the repair manual) A good bodyshop tried to reset mine w/no luck.It had 6 errors that my other shop couldn't clear either. I removed it and matched the SR# to one on ebay for $100. That fixed it.

Russell Ormerod

did you fix your srs lamp problem?
Reason is that turned the ignition on while the airbag was unplugged.
On the older mercs you could check and reset airbag memory simply by grounding diagnostic line. if you still stuck i will check further for you

Hi Russel, which is the diagnostic line? Thanks!

Hey Mber...

I'm experiencing the same problem you had... My car was originally throwing the SRS light and the problem was diagnosed as a faulty child occupancy sensor in the front passenger seat (common problem). In an effort to try to save some money, I decided to remove the seat and replace the sensor myself (I'm very mechanical). Problem is though that I couldn't complete the job in one afternoon and had to drive the car for a few days (without a front passenger seat) until I could finish the job.

Then when I brought it back to my mechanic to have the SRS reset, he was not only unable to clear the code - but found several more that appeared that were not there previously.

He's got my car as I write this, trying to figure out how to get the system to reset. Odd thing is that although he's able to communicate with the SRS module to read the codes - every time he attempts to clear them he gets an error message that says "Unable to Communicate With Control Module".

After reading your post, I'm thinking that maybe I fried my module by driving the car for a few days without the front passenger seat.

I'll hear from my mechanic tomorrow but he's already told me that if he can't clear the codes, I'll have to take it to the stealership. And since I'm not in a financial position to do that, and since I really don't want to sacrifice any arms or legs - I'll then have to do what you did - remove the SRS module, get the #'s off of it and match it up with one on ebay. My mechanic has even suggested this too.

Anyway - thanks for offering your experience. It's giving me insight into the very same problem which I'm now experiencing.

I really appreciate these forums and the folks on here (like you) who take the time to provide input. All of which goes to prove the adage that knowledge is only good if it's shared.

Thanks,
Mark

Having similar issue here.

I disconnected the airbag cable for a few weeks, then finally reconnected yesterday. However, SRS light stays on. My scanner doesn't show any faulty code and cannot reset either.

Not sure why this has to be the case. Nothing else changed, it was a simple disconnect and reconnect.

When you guys refer to SRS module, is that the controller box for airbag / window / speaker? Or the airbag itself?

khomer2

Why would you have the need to disconnect the airbag cable ?
(Unless of course, you're replacing a seat sensor)

Where are you scanning from?
What scanner are you using?

I was planning to transfer the guts to the new door shell.

Scanned from underneath the driver side.
