Re: air bag light blinking

If its 45, I had this SAME exact code - LH Radiator Primary Crash Sensor Not Mounted to Vehicle Properly

It ended up being the connector in the harness under the battery tray was corroding (tray was holding water/coolant from a leak I'd had and it was messing with the harness)

If you go to check it out, be sure to disconnect the battery and leave it disconnected for a while..

54 is : Intermittent or Repaired Primary Crash Sensor Circuit Shorted to Ground

Not sure where to start with that one if its 54..

Re: air bag light blinking

im just curious, do both sensors need to activate to deploy the airbag? i would hate for that thing to go off randomly cause the sensor was either faulty or had correded wiring...

Re: air bag light blinking

The light should flash a code a few times, then stay lit, showing the air bags are "shut off". Its basically a safety feature, if the computer finds a prob then it shuts them off as to not cause unwanted deployment.

You want to be careful with it, as - in theory - static charge can set off an airbag, but you should be fine with the battery disconnected

Airbag codes can be found Mustang 1995 Air Bag Diagnostic Codes <-- that's how I figured out my code when mine had the same issue..

Mine flashes constantly because there are no airbags in the car. I wish I could figure out how to turn it off.

I'm pretty sure the foxes used a one ohm resistor for the airbag simulators.. I remember checking one with an ohmmeter, it was pretty much right on the dot.. Head to radio shack and pick up a one ohm resistor, a bit of wire and I'm sure you could get it to work

You can also get the simulators that are used for diagnosis - rotunda tool # 105-00008

I think 93 is different (2 ohm?) and part # would be the same as the 94/95 systems - 105-00010

Yes both sensors need to activate to deploy, unless you induce voltage yourself! Even if you ohmed an airbag that could make it deploy!
