Inspection Procedure 1: Scan tool (M.U.T.-III) cannot Communicate with the Electronically Controller AWD System: 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.

STEP 1. Scan tool (M.U.T.-III) CAN bus diagnostics
Use Scan tool (M.U.T.-III) to diagnose the CAN bus lines.

Q: Is the check result normal?
1. YES: Go to Step 2.
2. NO: Repair the CAN bus line (Refer to DIAGNOSIS ). On completion, go to Step 2.
STEP 2. Voltage measurement at the AWD-ECU connector
1. Disconnect the AWD-ECU connector.
2. Turn the ignition switch to the ON position.
3. Measure the voltage between the AWD-ECU wiring harness side connector terminals 4WDF, IG16 (Ignition switch "ON") and the body ground.
  OK: System voltage
Q: Is the check result normal?
1. YES: Go to Step 3.
2. NO: Repair the connector(s) or terminal(s) or wiring harness.
STEP 3. Resistance measurement at the AWD-ECU connector
1. Disconnect the AWD-ECU connector.
2. Measure the resistance between the AWD-ECU wiring harness side connector terminals No. GND1 and the body ground.
  OK: Continuity exists (2 Ω or less)
Q: Is the check result normal?
1. YES: Go to Step 4.
2. NO: Repair the connector(s) or terminal(s) or wiring harness.
STEP 4. Retest the system.
Q: Does the malfunction occur again?
1. YES: Replace AWD-ECU (Refer to AWD-ECU ). Then go to Step 5.
2. NO: The trouble can be an intermittent malfunction (Refer to HOW TO COPE WITH INTERMITTENT MALFUNCTIONS ).
STEP 5. Retest the system.
Q: Does the malfunction occur again?
1. YES: Diagnose again from Step 1.
2. NO: This diagnosis is complete.
