    • CAN or ISO circuit fault; all electronic control units no response/not equipped, refer to MODULE COMMUNICATIONS NETWORK .
    • No response/not equipped for SJB, refer to MULTIFUNCTION ELECTRONIC MODULES .
    • System passed, retrieve and record the continuous diagnostic trouble codes (DTCs), erase the continuous DTCs and carry out self-test diagnostics for the SJB.
