I am getting an "airbag fault" warning on the LCD and the airbag light stays on.

I just reinstalled the cluster after replacing the LCD, and while I was running output tests to re-calibrate the needles, the green connector came off momentarily while the cluster was powered. I suspect that may have had something to do with the airbag MIL and warning message.

I did a full scan and it showed this ABS code:

Control Module Part Number: 8E0 614 111 AH
Component and/or Version: ABS/ASR 5.3 FRONT D10
Software Coding: 00022
Work Shop Code: WSC 00028
1 Fault Found:
01203 - Electrical Connection between ABS and Instrument Cluster
31-10 - Open or Short to Ground - Intermittent

I cleared it and it didn't come back after driving around a few blocks.


When I do a full scan it doesn't show any airbag codes.

I am not sure how to go about clearing the airbag warning with vag-com (I have an older version). Do I need to run some output test or adaptation on a controller? Which one? Can someone walk me through the steps?

The car is a 2000 sedan, manual.

Here is the full scan which shows all the controllers on this car:
I am not sure when the P1113 came on. I'll clear that too and see if it comes back.

If the airbag control module was “triggered” from what I remember the control module itself will have to be reset (can’t be done via OBD2 reader/scanner). Also, the airbag error codes wouldn’t come up with your standard scanner.

I haven’t done it since back in 2006, I had a clockspring issue that triggered the fault and replaced it but fault light stayed on. I found a guy on eBay that did the module reset, not sure if it can be done by yourself nowadays.

Edit: noticed you had access to vag, I didn’t back then and don’t have much experience with it. Only speaking about the standard OBD scanners which got me by back then.

Update:
The airbag module obviously was there (address 15) but the vag-com version I have is old, and it excludes that module from autoscans for 2000 models. When I went in the module there were these codes:

Control Module Part Number: 6Q0 909 605 B
Component and/or Version: 03 AIRBAG VW5 0003
Software Coding: 12339
Work Shop Code: WSC 00028
2 Faults Found:
00532 - Supply Voltage B+
07-10 - Signal to Low - Intermittent
01317 - Control Module in Instrument Cluster (J285)
49-10 - No Communications - Intermittent

I cleared them, and it's all good now. To anyone else that may be thinking of working on their instrument cluster, make sure you have a fully-enabled VCDS. If you don't have that, disconnect the battery before pulling out stuff, and make sure all connections are tight before reconnecting the battery.

But yay for a MAF that now works even when it gets hot inside the car. (I got used to it not working, but it gets annoying annoying part is when the cluster beeps and you can't see the text message on the LCD.)

My 1996 A4 consistently exhibits air bag B+ faults when scanned. I attribute these to the battery sometimes getting pretty flat when I go several days without driving it. I get a similar warning about the ABS sometimes.
