I have an X351, AWD, 2015. Well, here we go again! (LOL) With the help of so many of you, I finally got my speed wheel sensors and O2 Sensors straight. (Wrong cables from Parts Geek or RockAuto) Those lights are out on the dash. Now, via my scanner, I have a "transfer case control module" code but it says it is "intermittent." Anyone want to tell me what the heck that is and what it intermittent means? I assume that in the AWD version of my XJ, that the module is on the firewall of the passenger side of the vehicle. Since it is intermittent, maybe the multi-plug connections are corroded? Plus, this also lighted the yellow triangle in the lower right corner of the dashboard. The code number is U0102-00 AND IT IS IN A CATEGORY OF THE ABS SYSTEM. Ideas....?
