Mitsubishi Outlander: Inspection Procedure

Inspection Procedure 1: Scan tool cannot communicate with WCM.

CAUTION Before replacing the ECU, ensure that the communication circuit is normal.

TECHNICAL DESCRIPTION (COMMENT)

If the scan tool cannot communicate with the WCM, the CAN bus lines may be defective. If the WCM does not work, the WCM or the power supply circuit may be defective.

DIAGNOSIS

Required Special Tools:

STEP 1. Using scan tool MB991958, diagnose the CAN bus line.

CAUTION To prevent damage to scan tool MB991958, always turn the ignition switch to the "LOCK" (OFF) position before connecting or disconnecting scan tool MB991958.

Mitsubishi Outlander. Wireless Control Module (WCM)

  1. Connect scan tool MB991958. Refer to "How to connect the Scan Tool (M.U.T.-III)".
  2. Turn the ignition switch to the "ON" position.
  3. Diagnose the CAN bus line.
  4. Turn the ignition switch to the "LOCK" (OFF) position.

Q: Is the CAN bus line found to be normal?

YES : Go to Step 2.

NO : Repair the CAN bus line.

STEP 2. Check the power supply circuit and the ground circuit to WCM.

Refer to Inspection Procedure 4 "Abnormality in WCM power supply and ground circuits".

Q: Are the power supply circuit and the ground circuit to WCM in good condition ?

YES : Go to Step 3.

NO : Repair the power supply circuit and the ground circuit to WCM.

STEP 3. Retest the system

Check if scan tool can communicate with WCM.

Q: Does the scan tool cannot communicate with WCM in good condition?

YES : The trouble can be an intermittent malfunction.

NO : Replace WCM and register the ID codes.

Inspection Procedure 2: The ignition key cannot be registered using scan tool.

TECHNICAL DESCRIPTION (COMMENT)

If only some ignition keys cannot be registered, the ignition key itself may be faulty. If no ignition key can be registered, the key assembly may have already been registered for another vehicle, or the WCM may be faulty.
