2012 Ford F-350 Super Duty XLT 6.7L (T) 6-spd (6R140)—1FD8W3HT0CEA61854
B0010 - Passenger Frontal Stage 1 Deployment Control

Hi everyone,

I have a 2012 Ford F350 in that had no air coming from the vents and I removed the dash and replaced the A/C evaporate because it was plugged completely so no air would flow through. All went well until I got everything back together and now have this airbag light on and the B0010-1A code saying that the circuit resistance for passenger dash airbag is below the threshold. I went back over the dash wiring for the plug on the airbag to make sure nothing was messed up and did some circuit testing confirmed that the dash side of things is good and between the plug on the Airbag module and the C212 plug that plugs into the dash there must be somewhere the wires are rubbed together. Was wondering if anyone ran into this issue before. I never did anything with the body side of the wiring just unplugged all the main plugs going to the dash (C212 being one of them) and removed the dash and installed again and now I have a wiring issue with the wiring I never even touched. I just don't want to have to unwrap the whole harness from firewall all the way to the middle of the cab to try to figure out where my connection is between the 2 air bag wires. Just a note - with the Airbag module C310a unplugged and dash C212 unplugged I have 0 ohms between the GRY/BLUE and VIO/GRN and those two wires are to have no connection of course. So has anyone come across this problem and knows where I should split the harness first? Thanks in advance for any help.

Make sure the black caps on the connector for the airbag are pushed in there are shorting bars in the connector for the airbag. You have to do the connector and then push in the center of it to release the shorting bars Also for diagnosis purposes disconnect the airbag an see if code changes to high resistance which would 8ndicate a good harness.

With airbag plugged in and unplugged I have the same code. There seems to be a connection between wires on the harness between the airbag module C310a and C212 dash. Between the airbag and c212 the harness is good.

I do mobile diagnostics for shops. Virtually every airbags call that I get is due to a tech not reinstalling the “security clip” on an airbag harness plug. Techs think that the clip simply prevents the plugs from becoming unlatched or separated but it also opens up the shorting bar (which intentionally shorts the deployment circuits together) so that the circuit is correct.

Make sure the clock spring sockets are properly connected if they are not. Remove clockspring unit and carry out continuity test. The problem is most likely from there. To assess clockspring or otherwise called spiral unit. Remove Driver airbag and steering wheel.

The diagram doesn't show a shorting bar on C212, but I would verify that at the connector. The shorting bar is always on the deployment side of the connectors (as opposed to the module side). Are the wires shorted to ground? If they are look for metal pinching the harness, if no continuity to ground, possibly plastic pinch point. With it being the airbag system, you almost have no choice but to…

I got the problem fixed. I had found my original problem before I asked for helped but after I got that fixed it seemed to have another problem and here there was none. The diagram doesn't show it but there is NO short bar on C212 but THERE IS one on C310A and that is what was getting me. There was not short in the system between C212 and C310A it was just the unidentified short bar in the…

I just looked on Prodemand again and I know notice that there is a short bar listed there. It was cut off on my page I was using. Pro demand needs to move the description over. And I should have studied that a little better. My mistake. I'm just glad to have this thing done and out of here. Been a headache the whole time.
