Airbag Flashing Code 13
I found the two front sensors and disconnected them. I still get code 13. The front sensors test OK with an ohmeter. With the front sensors disconnected I used a voltmeter to check for voltage looking in toward the safing sensor. I measured 12 volts on one of the pins so I assume the safing sensor is bad. The info from the web site Steve83 shows the location of the safing sensor in the left side kick panel. Has anyone ever seen the safing sensor? Can you describe it? Exactly where is it located?
How do I get to it?
Thanks for any help provided.

Airbag Flashing Code 13
I found the safing sensor mounted on a bracket behind the rear passenger side kick panel. It has a round 5 pin connector attached. I removed the sensor and started the truck, still get code 13.
Does this indicate the failure is in the air bag diagnostic module?
Does anyone know how to test the safing sensor with an ohmeter?

Airbag Flashing Code 13
Send me a real e-mail and I'll send you a diagram and some instructions off my Ford CD. It may take a few days, though...

Airbag Flashing Code 13
Thanks steve83 got the code definitions.
I pulled the airbag off and replaced it with a 2.7 ohm resistor. Got the 13 code so I pulled all sensors and still get code 13.
The two connections to the airbag are not shorted to ground or the hot side.
I removed the positive battery connections and the sensors then tested with an ohm meter. I checked the wiring harness to ground. I don't have the complete schematic so I can't figure the best method to test the wire harness. I don't know how the diagnostic computer is wired to monitor the sensors. Any advise on this?

Airbag Flashing Code 13
I'd guess just unplug EVERYTHING and test between each terminal of each sensor/airbag and the corresponding color at the computer connector. If everything checks out, I'd guess the computer is bad, but it won't prevent the airbag from deploying in a wreck, so you're not in any danger.

Airbag Flashing Code 13
Thanks steve83,
That was how I figured to procede. I priced the computer at $180 at the local dealer. I'll post back with the final fix if lucky enough to find it.

Airbag Flashing Code 13
Thanks Steve83
Today I disconnected the two front sensors and tested again. The sensors have a three pin connector attaching them to the wired harness. One pin of the sensor is attached to chassis. The other two pins are not shorted to the chassis but an ohm meter indicates continuity between them. Both front sensors measure the same.
Does this indicate the chassis pin is one side of the fire contact and the other two pins are set up such that one pin is the fire bag connection and the other is the computer monitor?

Airbag Flashing Code 13
I thought I sent you the basic diagram for the airbag. I know I didn't send the airbag MODULE wiring, but it's just a ground wire going to BOTH front sensors, then back together to the "safing" sensor (the one in the R shoulder belt reel cover), then to the airbag, then to main battery power. If the safing sensor and EITHER front sensor closes the circuit at the same time, the airbag detonates. I've scanned the EVTM pages that show the circuit very simply, but it's still a 1M .jpeg. If you want it, send me another real e-mail.
