Got the truck back from the painters. New clock spring (0.56ohm resistance measured) installed. Still got the B1932 code.

So going by the Pinpoint test this would indicate the RCM is shot. Does anyone now the resistance of the Airbag module itself so I can use a resister and confirm that its the RCM?

 

So, you buy and plug in a air bag simulator to the clockspeing connector at the base of the steering column
That takes the drivers side air bag out of the equasion
Then if you still have the light and code you replace the module / backup power supply assembly
Post 8 about reading between the lines
After running through the pinpoint test steps several more times, you might buy the simulator(s), they help with diagnosis
We used to have a few airbag modules kicking around to test with at the dealer to make it easier
I have one and a RABS module in my toolbox now
There are no specs for air bag module resistance

 

Ok thanks. Any idea where to buy the correct simulator? There are so many different generic sims available but I can't seem to find the correct one.

 

OTC 7956 comes up on Google
The connector is what is or should be different
Maybe take a photo of your clockspring connector where you would be plugging a sim into
I will check my selection and maybe send you one of the expensive little bastards
If I remember right, I have oddball ones left like for Probe and such

 

Well, maybe I do have one.

 

So OTC 7956 comes up as a 2 ohm simulator. Is there some reason I can't use a 2 ohm resistor? i.e.Is there something else in the sim other than a resistor?

 

The simulators were 1 ohm IIRR but no matter, and yes, you could use a one- or 2-ohm resistor to test with
The simulators were advertised as a very good 1 ohm resistor (that was exactly one ohm) (maybe 2 ohms) I cant remember exactly but will measure the resistance on one of my sims and report back
Looks like some are 1 ohm and some are 2 ohm
The only two things I have ever replaced to fix an air bag lamp on were the backup power supply (module assembly) and the clocksprings
Hundreds of clocksprings a couple of modules
There is a thermal limiter inside the module that can burn out during deployment
Sometimes it burns during deployment and sometimes it does not
The codes help determine the problem
