DYNAMIC TORQUE CONTROL 4WD/AWD SYSTEM DIAGNOSIS SYSTEM


  1. DESCRIPTION

    Dynamic torque control 4WD/AWD system data can be read through the Data Link Connector 3 (DLC3) of the vehicle. When the system seems to be malfunctioning, use the GTS to check for malfunctions and perform repairs. Therefore when there seems to be a problem with the dynamic torque control 4WD/AWD system, use the GTS or SST to check and troubleshoot it.

  2. CHECK DATA LINK CONNECTOR 3 (DLC3)

      2. Turn the ignition switch to ON.

      3. "DIAGNOSIS CODE AWD" is displayed on the multi-information display, and the 4WD ECU assembly checks the system for malfunctions.


        • If the AWD control system is normal, "DIAGNOSIS CODE AWD FF" will be displayed on the multi-information display.

        • If the AWD control system is not normal, "DIAGNOSIS CODE AWD XX (DTC)" will be displayed on the multi-information display.

        • Although Test Mode is not set for the dynamic torque control 4WD/AWD system, a message will be displayed on the multi-information display when Test Mode is activated for checking the VSC, etc.

        Tech Tips


        • Test mode DTCs will not be stored because test mode is not set.

        • If the systems above are not displayed on the multi-information display, there may be a malfunction in the TC and CG terminal circuit.

        • If the AWD warning check result is not normal, proceed to troubleshooting for the AWD warning circuit.
