    Probably. You have to have a reset. Look it up on line, or call a dealer. It may have to be done with a computer or maybe just several on-off with the key. BTW/If it runs, drive it.

    Mack mechanic got back to me

    SPN 251 Time
    #
    Time and date data missing on J1939
    Possible causes-
    Instrument cluster, harness or harness connector.#
    #
    If it was me, I would reprogram all modules and recheck.
    #

    He's never lead me astray before.....
