COMMENTS ON TROUBLE SYMPTOM

• If the drive mode cannot be switched by pushing the 4WD switch, the 4WD switch, the wiring harness wires between the 4WD-ECU and the 4WD switch, the wiring harness wire in the earth circuit for the 4WD switch, the 4WD-ECU or the combination meter may have a problem.

PROBABLE CAUSES

• Damaged wiring harness and connectors
  
• Malfunction of 4WD switch
  
• 4WD-ECU malfunction
  
• Combination meter malfunction

DIAGNOSIS PROCEDURE

STEP 1. M.U.T.-III CAN bus diagnostics.

Use M.U.T.-III to perform the CAN bus diagnosis.

Q. Is the check result normal?

	Go to Step 3.

	Repair the CAN bus lines (Refer to GROUP 54C - Troubleshooting ). After repairing the CAN bus line, go to Step 2.

STEP 2. Retest the system.

Q. Does the malfunction occur again?

	The trouble can be an intermittent malfunction (Refer to GROUP 00 - How to Use Troubleshooting/How to Cope with Intermittent Malfunctions ).

	Go to Step 3.

STEP 3. M.U.T.-III actuator test.

Combination meter item No.5: Meter illumination (Refer to GROUP 54A - Combination Meter ).

Q. Is the check result normal?

	Go to Step 4.

	Replace the combination meter. (Refer to GROUP 54A - Combination Meter ). Then go to Step 8.

STEP 4. Resistance measurement between the 4WD switch connector terminals

(1)Remove the 4WD switch (Refer to ).

(2)Measure the resistance between the terminals (Refer to ).

Q. Is the check result normal?

	Go to Step 5.

	Replace the 4WD switch (Refer to ). Then go to Step 8.

STEP 5. Wiring harness check

(1)Check the wiring harness between the 4WD-ECU connector (terminal sw-1) and the 4WD switch connector.

(2)Check the connector(s) or terminal(s) or wiring harness above for damage or other problem.

Q. Is the check result normal?

	Go to Step 6.

	Repair the connector(s) or terminal(s) or wiring harness.

STEP 6. Resistance measurement at the 4WD switch connector

(1)Disconnect the 4WD switch connector.

(2)Measure the resistance between the 4WD switch wiring harness side connector and the body earth. OK: Continuity exists (2 Ω or less)

Q. Is the check result normal?

	Go to Step 7.

	Repair the connector(s) or terminal(s) or wiring harness.

STEP 7. M.U.T.-III data list.

Check the following data list. (Refer to ).

Item 1: AWC (4WD) control mode

Q. Is the check result normal?

	Go to Step 9.

	Go to Step 8.

STEP 8. Retest the system.

Q. Does the malfunction occur again?

	Replace 4WD-ECU (Refer to ). Then go to Step 9.

	The trouble can be an intermittent malfunction (Refer to GROUP 00 - How to Use Troubleshooting/How to Cope with Intermittent Malfunctions ).

STEP 9. Retest the system.

Q. Does the malfunction occur again?

	Troubleshoot the combination meter multi information display (Refer to GROUP 54A - Troubleshooting/CAN Bus Diagnostics Table ). Then diagnose again from Step 1.

	This diagnosis is complete.
