    FCW OFF after diff change

    Hello.
    Searched everywhere, including here, and still cannot find an answer as to how to get rid of this FCW OFF light after a diff change.

    I know it?s possible to get it fixed via a dealer. But I?d like to know how to do it myself.

    I find it bizarre that not many people are having this problem.

    I'm suffering the same fait after a gear change.

    HP tuners took me out of limp mode, but no FCW/ACC.

    Some say a Diablo tuner will fix it. I have one but never went into system with it yet.

    Hello,
    Sorry for the late reply.
    I've been to two dealers, and they don't even know how to do it.
    The Mopar Mechanic that did it for me initially, no longer works there.

    I have been told there is software called Alfaobd, that can possibly do the job.

    https://www.alfaobd.com/

    I'm going to look in to that in the meantime. If I find out how to do it, I'll let you know here.

    I realize this is a year old post. But figured I would answer it incase anyone else has had this issue.

    I have had this happen twice so far. All that needs to be done is to get an adaptive cruise calibration done. AlfaODB can get it done. Other bidirectional scanners can do it ask well. As well as some larger alignment shops with more modern alignment racks. They put your car into calibration mode and drive it for like 15-20 minutes and once fully calibrated you will get your forward collision back.

    Good to know, now can you provide instructions? I have alfaOBD.

    Just go to the Cruise Control section. You will only one option to do an alignment. Go thru step one but don't touch the sensor. Just pretend you did it. Then go to step 2 and take it for a ride.
