    All those things are controled by the same cluster switch aka blinker switch, disconnect the batteries for 15 min to reset the computer, your cables are prob lose and caused it to get out of whack.

    My 2016 Volvo 780 has ECU on fault code, engine light on, cruise not working. Dealer found no code while in shop. Any ideas where to check for issue correction? Truck running fine so far.
