    Sounds like his Computer is connecting on just the J1708 and maybe the J1939 communication circuits. And missing the CAN circuit. If Can is working he should get MCM, ACM, and CPC or ICU4me. If he has Detroit software he needs to make some adjustments in his options

    Newer Detroit software (DDDL 8) won’t fully connect of the blue tooth nexiq. You have to change PC settings and run with the USB cord.

    Or it could be just what you get with aftermarket.

    The Options are in his laptop computer program. So he can see all of your trucks computers.
