Thanks. I had the entire steering wheel apart and will start there. I also had the passenger AB out and the entire dash out. Funny thing is that the engine ran fine for an hour or so. I am going to pull the drivers side AB and replace it with a 3.9 Ohm resistor then check it form the connector on the AB Module. That will tell me if the clockspring is OK.by rkellison - Main Forum
OK, I have part of the mystery solved or at least narrowed down. It appears that the problem lies in the AirBag module. If I put a meter on the "Crash" output of the AB module I can see it start out at 12V as it goes through the self check. When it completes it, the voltage drops to 2.5v and the AB light comes on. If I open that circuit up(cut the wire) and apply a 12v signal to it, the engine crby rkellison - Main Forum
That is the unit under the Driver seat, correct? If so, I have and it is good.by rkellison - Main Forum
What you describe is a very close match to what I am seeing. Is there any material that tells me how to troubleshoot the system other than the Porsche manuals? I have them and they are pretty remedial. Mostly continuity testing. They also call for a special tool Part number 9516 and 9516/1. I assume they are a load device that allows testing without putting a voltage across the actual airbagby rkellison - Main Forum
Yep. And verified that the relay is good also. I have verified that the crank sensor is ok. Any idea wwhat "Current Fault Codes 0 module failed to initialize" means on the AB module?by rkellison - Main Forum
Ah, brain cramp. Inertia sensor. But if it were that, I would see a code in the AB module. To me it appears that the AB module is not talking to the DME.by rkellison - Main Forum
I assume that you are talking about the crankshaft sensor at the flywheel. If that were it, it would show a CEL error code in the DME. I do not have any DME errors. The one that conrcerns me is "Current Fault Codes 0 module failed to initialize".by rkellison - Main Forum
I just got through with a full rebuild on my 996. The IMS bearing and shaft self destructed causing the rebuild. After getting it all back together, I started the engine and ran it for 20 minutes. Several stops and starts later I backed it out of the garage revved it a few times to 3000 rpm and the CEL came on and the engine shutdown. Now it will turn over but will not start.
