Diagnostic trouble code BCU 523746.31 is activated when the Body Control Unit (BCU) detects no current flow at the signal output designated for activating the tractor BUS system. This condition suggests that the circuit is either shorted to a positive supply lead or there is an internal interruption within the control unit itself. Such faults…
