Diagnostic Procedure

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. Measure the resistance at the AWC-ECU connector. 
    1. Disconnect the connector, and measure at the wiring harness side.
    2. Resistance between AWC-ECU connector terminal FSL+, FSL- and body ground

      OK: No continuity 

    Q: Is the check result normal? 

    1. YES:  Go to  Step 3.
    2. NO:  Go to Step 2.
  2. STEP 2. Check the wiring harness between electronic control coupling solenoid (front) connector and AWC-ECU connector terminal FSL+, FSL-. 

    Check the power supply, ground line for short circuit (for short to the power supply).

    Q: Is the check result normal? 

    1. YES:  Go to Step 3.
    2. NO:  Repair the defective connector or the wiring harness. Then go to  Step 7.
  3. STEP 3. Check of the electronic control coupling solenoid (front) 

    Refer to ELECTRONIC CONTROL COUPLING SOLENOID (FRONT) CHECK < VEHICLES WITH S-AWC >  .

    Q: Is the check result normal? 

    1. YES:  Go to Step 4.
    2. NO:  Replace the transfer assembly (Refer to TRANSFER ASSEMBLY < AWD >  < CVT > or TRANSFER ASSEMBLY < A/T >). Then go to  Step 7.
  4. STEP 4. Measure the resistance at the AWC-ECU connector. 
    1. Disconnect the connector, and measure at the wiring harness side.
    2. Resistance between AWC-ECU connector terminal SOL+, SOL- and body ground

      OK: No continuity 

    Q: Is the check result normal? 

    1. YES:  Go to  Step 6.
    2. NO:  Go to Step 5.
  5. STEP 5. Check the wiring harness between electronic control coupling solenoid (center) connector and AWC-ECU connector terminal SOL+, SOL-. 

    Check the power supply, ground line for short circuit (for short to the power supply).

    Q: Is the check result normal? 

    1. YES:  Go to Step 6.
    2. NO:  Repair the defective connector or the wiring harness. Then go to  Step 7.
  6. STEP 6. Check of the electronic control coupling solenoid (center) 

    Refer to ON-VEHICLE SERVICE .

    Q: Is the check result normal? 

    1. YES:  Go to Step 7.
    2. NO:  Replace the electronic control coupling (center) (Refer to ELECTRONIC CONTROL COUPLING ). Then go to Step 7.
  7. STEP 7. Check whether the DTC is stored again. 

    Q: Is DTC No. C1610 stored? 

    1. YES:  Replace the AWC-ECU (Refer to AWD-ECU ). Then go to Step 8.
    2. NO:  Intermittent malfunction (Refer to HOW TO COPE WITH INTERMITTENT MALFUNCTION ).
  8. STEP 8. Check whether the DTC is stored again. 

    Q: Is DTC No. C1610 stored? 

    1. YES:  Return to  Step 1.
    2. NO:  This diagnosis is complete.
