My issue is I get Airbag code 6 only when engine is running. History; The clockspring (CS) has been replaced with a brand new Doorman CS. The Doorman CS has been slightly modified to fit the Mustang. I put the factory plug ends on the Doorman CS making sure to keep the wires in the correct locations. When the key is turned to the run position the Airbag light comes on as normal and then turns off as normal. I waited several minutes to ensure the code 6 wasn't triggered. Then when the key is turned to run/engine on the Airbag code 6 is triggered. This happens whether the Airbag is in place or I put a 1 ohm resistor in the CS plug in place of the Airbag.
Any help will be very much appreciated!!

light is normal

its a bulb check

you have a wiring or module issue

check volt at module

I thought when the airbag light goes out that the diagnostic module has checked the circuits and is satisfied with the reported values. Additionally I sent the module to Airbag Systems Inc and it came back reported to be in good working condition. I did check the voltage at the module. Does it matter whether the code 6 is present during the test or not? I think I got 1.14 volts back probing at the module.

then you have a wiring issue

what is the voltage from the module airbag unplugged?

is it the same plugged?

What voltage and resistance reading should we be seeing at the C202 connector?

Folks,

I have been trying to help Joel with this issue, I will try my best to clarify where we believe things stand as of now.

Steps already taken and other things to consider -

1. Airbag diagnostic computer and backup battery pack were recently sent out for repairs including the repair of the deployment safety fuse, before this step was done the airbag system was producing Code 10.
2. No wiring short was found at this stage.
3. After servicing the airbag diagnostic computer and battery back up the fault code 10 switched to a fault code 6.
4. The system now seem to function normally with the ignition on, but only before starting the engine. In other words the systems proves with the key on, engine off, but once you start the engine the code 6 returns.
5. Based on step 4 results we believe that the currently installed clock spring is working as expected, yet we still are getting the code 6, which as we understand indicate either high or open resistance in the airbag circuit.

Below is the best diagram we have found, my question is what voltage and resistance reading should we be seeing at the C202 connector?

Thanks in advance,

Dan Ney

Here is a second diagram, this one seems to be less accurate

there is an open most likely clockspring

I'm embarrassed to admit it but it was a bad Diagnostic module. I made the mistake of thinking that the Diagnostic module was not the issue because I had it "repaired" and then sent back to be "re tested". I sent an email to ASI to see what they check/repair. I opened up the old unit to find a burnt circuit board along the edge and a resistor jumping the thermal fuse, which may be fine but I still had code 6. I would not recommend their services based on my outcome.
A special thanks to Indy for help and support.
