Airbag light on.

[Silverado]

Every time I start my truck, the airbag light will flash for a while, then stay on steady.

I read a thread about the sensor under the passenger seat being a trouble spot, so today I pulled the seat to have a look.

There's no sensor under there... at least not on mine. No clips, no wires, nothing.

Whisky Tango Foxtrot... over?

FWIW, the light does the same thing whether I turn the pass airbag off or not.

The flashing is a code. It is a two digit code. It will tell you if the problem is continuous or intermittant. I had a similar problem on my Taurus. Turned out being a break in a wire deep inside the wiring harness. Was a PIA trying to find it. Had to isolate the wire by testing voltage and continuity, then unwrap the harness to find it.

Check the fuses related to the airbag. The wiring diagram for my 97 Ranger shows:

Airbag fuse #10, 10A (hot at all times) in engine comartment fusebox

Fuse #6, 7.5A (hot in run) under dash

Fuse #15, 7.5A (hot in run and start) under dash

Here is a link to some Ford airbag codes:

I think you mean to count the number of flashes? I'll do that, thanks.

 

[BlaineM]

Yes, count the flashes. eg. if the code was 23, there would be 2 quick flashes, a brief pause, then 3 quick flashes. This sequence would be repeated 3 times, then the warning light would stay on until the ignition was turned off.

After you find and fix the problem, you may still get a different code. eg. after I repaired the broken wire on my Taurus, I got a second code saying there was an intermittant power interuption because the old problem stayed in the computer's memory until I manually erased it with a code reader. (I guess it does that for safety reasons for airbags.)

Thanks BlaineM... but my light flashes 27 and that code's not listed in the link? LOL

OK, found this on another forum:

yes, for many Fords code 27 airbag is a failed PAD switch for the enable/disable child passenger front side switch

So do you think that means the actual switch ie: the one you turn with the key?

 

[BlaineM]

Not the ignition switch but the Passenger airbag deactivation switch. That statement would only apply if you have the Passenger Airbag Deactivation Switch (PAD) on your vehicle. I don't have that feature on my truck so I'm not familiar with how the switch looks.

I googled airbag code 27 and found this:

From the wiring diagram I would have to determine that the Passenger airbag deactivation switch is part if the PAD module (passenger airbag deactivation module. That thread seems to suggest that a burned out bulb on the PAD module will throw the code 27. If the bulb is not burned, I suggest checking the wiring connections going into the PAD module. Before you do this, disconnect the neg cable from the battery for 10 minutes. That will allow the airbags to power down (so you don't accidently fire them off). Disconnecting the battery for 10 minutes also may erase the code from memory.

I had the 2-7 code that I had on mine a while back and it was the light bulb for the pass airbag switch. It didn't even look burnt out, and I had trouble finding an exact one to replace it...so I got a similar one and sautered (sp) it in. No probs since.
