The service 4WD system light may illuminate with no fault codes stored in the final drive control module (FDCM). Our technicians tell us a software update for the FDCM is available to correct this concern.

    FDCM recall was applied and no working 4wd Low after. Service 4wd system warning. Still not resolved by the dealer - they are claiming it wasn't the reflash that caused the fault

    Service 4 wheel drive. I was going through my winters checks, and engaged in and out of 4 low. I went through this procedure 3 times, properly. After the final test it came on. The green light that illuminates at the 4 low switch, also went out an will not come back on. Had the n23 update done, but the problem still exists. It will not go into 4 low, with a service light, and no green light at switch. Is this a fuse problem? It sure did act as one when it happened. The service guys at jeep are not being forth coming with any information, it's as though they are being ordered to be tight lipped. Anybody?
