Airbag Fault Codes

[Romaniac2k]

Hi Guys,

 

I picked up an 02 996tt a few months back. The airbag light was on when I got it. I finally had a chance to hook up the Durametric scanner. Below are the current fault codes and they cannot be erased:

 

1 - Airbag warning light

194 - Control module internal fault - All fault codes over 100 indicate a critical fault and usually require a new control module

3 - Supply voltage

 

Will a new or repaired control module fix the issues? Appreciate any input.

 

Thanks!

I would reset the airbag light first; drive around the block, and see if it returns. Might save $$$$$

 

Remember; the fault code is an end result; just because it lists the module as the "Fix" doesn't mean it's the original problem.

@PWS I was hoping to reset the light when I hooked up the Durametric. Unfortunately, they will not erase.

Is this a real Durametric or a knock-off?

You should be able to clear fault codes.

It's a real Durametric. From what I've been reading, seems like airbag codes over 100 are hard codes and can't be erased. I will give it another try tonight. I attached a photo of the readout. Thanks!

Did you  check fuse E1?

If it is good then you likely have a bad air bag control unit.

I have not. I will check it tonight when I try to reset the faults. Let you know what happens. Thanks guys!

Checked the fuse last night and it was good. Ran the Durametric again and could not erase the code. Looks like it's a faulty control unit. Can I get a used one? Is it simple plug and play or will it need to get reprogrammed?

[Loren]

As long as it is the same part number it should be plug n play.

Just ordered the matching part # module off ebay from an 04 996tt donor car. I'll keep you guys posted. Thanks!

Changed out the airbag module and the was able to clear all the codes on the new module with the exception of code 72 (child seat detection). The dealer said they should be able to address that code with their computer.
