Diagnostic Item 12: Diagnose when the scan tool cannot receive the data sent by AWD-ECU < AWD >: Diagnosis

WARNING: This page is about a different car, the 2014 Mitsubishi Outlander. However, it is still accessible from the selected car via links, so may be relevant.
  1. STEP 1. Connector check: joint connector (CAN-3) and AWD-ECU connector 
    CAUTION: The strand end of the twist wire should be within 10 cm from the connector. For details refer to SERVICE PRECAUTIONS  .

    When checking the joint connector, ensure that its wiring harness side and its short pins are not damaged.

    Q: Is the check result normal? 

    1. YES:  Go to Step 2.
    2. NO:  Repair the defective connector. Replace the joint connector as necessary.
  2. STEP 2. Resistance measurement at joint connector (CAN3) and AWD-ECU connector. 
    CAUTION: A digital multimeter should be used. For details refer to SERVICE PRECAUTIONS  .
    CAUTION: The test wiring harness should be used. For details refer to SERVICE PRECAUTIONS  .
    1. Disconnect joint connector (CAN3) and the AWD-ECU connector, and measure at the wiring harness side.
    2. Turn the ignition switch to the LOCK (OFF) position.
      CAUTION: When measuring the resistance, disconnect the negative battery terminal. For details refer to SERVICE PRECAUTIONS  .
    3. Ensure that the negative battery terminal is disconnected.
    4. Continuity between joint connector (CAN3) terminal No.5 and AWD-ECU connector terminal No.5 < Vehicles without S-AWC >

      OK: Continuity (2 ohms or less) 

    5. Continuity between joint connector (CAN3) terminal No.16 and AWD-ECU connector terminal No.13 < Vehicles without S-AWC >

      OK: Continuity (2 ohms or less) 

    6. Continuity between joint connector (CAN3) terminal No.5 and AWD-ECU connector terminal No.23 < Vehicles with S-AWC >

      OK: Continuity (2 ohms or less) 

    7. Continuity between joint connector (CAN3) terminal No.16 and AWD-ECU connector terminal No.24 < Vehicles with S-AWC >

      OK: Continuity (2 ohms or less) 

    Q: Is the check result normal? 

    1. YES:  < All the resistances measure 2 ohms or less > Power supply to the AWD-ECU may be suspected. Diagnose the electronic control AWD. Refer to REAR AXLE DIAGNOSIS .
    2. NO:  < Either or all of the resistances measure more than 2 ohms > Check the intermediate connector, and repair if necessary. If the intermediate connector is in good condition, repair the wiring harness between joint connector (CAN3) and the AWD-ECU connector.
