Air bag light on

[Capecod 02/4S]

Code reader says the fault is ignition circuit side air bag driver unable to evaluate.

Can anyone tell what could cause this please?

[Capecod 02/4S]

Oh, it’s an 02 C4S. I was asking questions about this yesterday under a separate posts. Brought it to a mechanic who read the code above. Thx

Did he or she give you the specific DTC code number? Without that, it is pretty much guess work....

Would I’d be something like 13-00?

No, DTC codes are usually P plus four digits, like P0301

[Capecod 02/4S]

The code was taken using a Snap on P1000 and there was no letter designation. Only 13-00 followed by the description I provided above.

Is this car a cabriolet?

OK, after some research into Snap-On diagnostic systems, and some translation of one fault code system into another, it would appear you may have a driver's side seat belt buckle issue. Porsche developed a fix for this which consists of a new buckle and its wiring harness, which seems to be a permanent fix. Parts are about $100 or so, and then the code can be cleared.

Good info JFP.

Would there be a TSB on that ?

Thanks ever so much for taking the time to cross ref the codes and help. Do you think once installed the snap
On tool can clear the code or maybe even my Schwann? The closest Porsche dealer is well over an hour away and I have yet to find anyone near me with PIWIS. Any chance you have a part number? Again many thanks

I invested in a Durametric in 2008, just recently upgraded to their Pro version. This tool clears Airbag Codes and does programming on certain Porsche models

I’ve owned this car 7 years. I’ve taken a deposit on it and this light just came on for the first time ever. It may be a deal breaker but I don’t want to buy a durametric.

I believe there was.

It might even clear itself once the repair is completed, but the Snap On tool will definitely clear it if necessary.

Last part number I have is 996-803-183-09, but as they have superseded this particular part a couple of times, I would check with a dealer parts department first.

And as replacing this unit is within the airbag system safety protocols, you need to read up on how to deactivate the system so you can work on it without getting a face full of air bag.

Well this is my 2cnd 911 . Owned the two combined for almost 20 years. Had both engines out and did the ims on the C4s and never once went to a dealer. Until now that is! Lol. Made an appointment for Wednesday as I have a deposit on the car and the light would stop the deal! Having PPI there too which although the car runs excellent concerns me they will be super nit picky. Thanks for your help but the more I read the iffy I felt about being able to resolve this myself. An airbag deploying would have freaked me out to say the least.

I went through this same episode a few years ago, and ordered the repair kit. The repair involved replacing pins in the belt connector, but the old pins would not budge (I guess you need a special tool for this). Instead, I bought a new buckle with connector-easy install, and cleared the code with a Durametric

[Capecod 02/4S]

Well I found a red wire with blue or purple stripe on it within the harness in the running board after of the trunk that had been chewed off. I was able to solder it��. The light is still on and my schwaben can’t clear it. I thought perhaps that wire wasn’t the problem but I took a look under the seat and seems there a red w purple stripe wire going to connector junction. So maybe all I need to do is have someone w the right tool clear it?!

[JFP in PA]

Seriously doubt it.

[Capecod 02/4S]

Well I broke down and drove an hour to Porsche today. It wasn’t the wire I suspected as they said they can’t even shut off or clear the code. Although I had an appointment to diagnose or fix it they sent me home. Told me they had to get pricing and would email estimate. I get home and they had pricing for a bunch of other stuff and want more $ to open the door and investigate more! What BS after I spent 1/2 a day and hundreds.

[Capecod 02/4S]

It was the airbag control module and with a used one installed I cleared the codes and light with a Schwaben.
