    It keeps telling me adaptive cruise control not working.

    Thanks in advance.

    @ajlouni My question for you, do you have a cow-catcher installed on your truck? Did you hit anything on your front bumper? The bracket is very sensitive for mis-alignment.

    Here's some wiring for your truck:

    You have potentially 6 connectors to look through that could have an issue in 5 different harness locations.

    If this seems daunting to you or you are unsure of these connectors, you might want to take your unit into an FTL dealer to get it looked at.

    No cow-catcher is installed on the truck, and didn’t hit anything on the front bumper either. I was driving down the highway and the ABA dash lamp light came on magically and told me adaptive cruise control not working. Parked the truck and went into the main menu to read the codes.

    There's no magic in ACC INOP because ABA is disabled. It makes total logical sense. The radar data is compromised somehow.

    If it's still INOP, check the wiring like the T/S says. Supply comes from SAM CAB.

    I finally went back to work today and turned the truck on and the code was gone. Drive it for a good 1000 miles and the code hasn’t came back on. Thanks for all your help not to sure what the problem was:
