I recently bought a use 2006 Grand Cherokee 5.7 HEMI Quadra-Drive II with 110,000 miles. The Service 4WD light is on and I have pulled a few codes. U140E Implausible Vehicle Configuration, C2100 Battery Voltage Low, and C2202 Original VIN mismatch.
I have done some internet searching and found some info on this “Service 4WD”, what I don’t know is if my Jeep has ever had the N23 Recall update, or the P73 so called fix to the N23...How can you find out if the previous owner had any recalls done?
Also I found a video on doing the #25 fuse pull fix. I have tried this 4 times trying it several different ways but it has no effect, I still have the same Service 4WD indicator on and it will not go into 4Low.
I was starting to think that I had a bad wheel sensor, but I think that would pull up when checking the codes…?
I’m starting to think I might need to find a new FDCM that has never had the update? If so does anyone know how to find one?
Or should I have a dealer do all update/recalls, if they have not been done yet?
Thanks in advance for any advice!
