2001 Ranger LFC 46

[DaveO_39]

My Ranger was backed into while idling and the air bags deployed. Very small dent in the left front of the bumper, hardly noticeable.

I purchased replacement Air Bags and the RCM that were taken from a 2001 salvage vehicle with no deployment.

I installed everything within 45 minutes and carefully reconnected the battery. Nothing blew up, no additional chimes, but I get a lamp fault code 46 (LFC 46).
I've seached the forums and Google and can't find the meaning of the LFC46. Can anyone help? How to remove/fix it?

I also scanned the vehicle with my OBDII scanner. No trouble codes and no mention of anything amiss.

Appreciate any help. I'd like to sell this vehicle as I've bought a larger truck.
(Asking $2000 under KBB if anyone is interested).

Have tried calling the Ford dealer about what the code meant?

I don't deal with dealers unless it is absolutely necessary!

In this case, "Bob" came through with this answer so I'm all set:

That is the code for incorrect resistance on the seatbelt pretensioner circuit (code 46 driver side, code 47 passenger side). It is a common problem and is usually caused by a poor connection under the seat. Turn off the ignition, open the connector, clean the pins and reassemble. Applying dielectric grease to the pins should make the repair last longer. In rare cases, the connector might need to be replaced.

My 2002 Ranger had the 46 airbag code and I cleaned the connector under
the drivers side and reinserted it and the code disappeared. Thanks for this tip!!!!

Is the connector under the seat for the extended cab version as well?

I can't seem to find it and the seat belts come from the back doors.

Thanks,

----> A little more searching solved my problem:

"The pretensioner built into the female side of the buckle. Sometimes stuff thrown under the sear catches the harness and pulls the connector just a little loose. "

---> Yes, even on the extended cab version, it's under the seat because it's "build into the female side of the buckle." Not knowing any better, I assumed that, since the belt tightens from the belt-end, that the pretensioner was there.

---> Anyway, I disconnected and reconnected the connection ... which was hanging loose because the tape holding it up had given way ... and the code (47) went away. I repositioned the connector firmly to the underneath of the seat with tie-straps instead of the original tape.

---> Hope this helps someone in the future.
