The 3 connections are 1) the R/F impact sensor mounted behind the front bumper on the frame rail, 2) C219 which is the 74 way connector under the dash, and 3) the ORC module which is under the front seat. Chances are the module or sensor failed. Wiring problems in the system are pretty rare.

thanks for the info , I replaced the sensor but the light still stays on . do I need to have it reset by a scan tool or will it go away on its own or will disconnecting the battery work?

If the code is still there, the problem hasn't been fixed.

I haven't checked to see if the code is still there as it cost $50.00 everytime i bring it to a garage to use the scanner but the airbag light is still on, does that mean the code is still there? if so does it mean it must be the module under the seat?

Thanks
Finvette

It could still be a module or wiring problem. In the long run, getting a correct diagnosis before throwing parts at the problem will likely save you money.

Instead of taking your truck in to get the codes scanned every time, do this instead.

1) Insert key in ignition
2) Cycle key from the off to the on position and back to off three times (ensure that you do not hit the point that the starter is engaged or you will have to start over)
3) Any codes that your truck may or may not have will be displayed either in the EVIC or the odometer.

I learned about this trick when I had my SRT4 that was always throwing codes.
To clear the codes after the issue has been remedied, disconnecting the battery typically does the trick.

As always, your mileage may vary.

Too bad this doesn't work for the airbag codes he's dealing with.

I know the sensor was gone as it had 1 of the prongs corroded off, so I assumed that was the problem , but after I replaced it the light stayed on. where exactly is the orc module as I do not see it under the seats. also is there a way to test it? do I need to remove the seats/carpet to see/ remove it?
