Diagnostic procedure

STEP

INSPECTION

ACTION
1
INSPECT MOTOR COMPONENT (SHIFT MOTOR)
•  Turn the engine switch off.
•  Inspect the motor component (shift motor).
•  Is the motor component (shift motor)?
Yes
Go to the next step.
No
Replace the motor component, then go to step 4.
2
INSPECT MOTOR COMPONENT (SHIFT MOTOR) WIRING HARNESS FOR SHORT TO GROUND
•  Disconnect the 4x4 CM connector.
•  Disconnect the motor component connector.
•  Inspect for continuity between the motor component connector terminals A, B, C, D (vehicle harness-side) and body ground.
•  Is there continuity?
Yes
Repair or replace the wiring harness, then go to Step 4.
No
Go to the next step.
3
INSPECT MOTOR COMPONENT (SHIFT MOTOR) WIRING HARNESS FOR OPEN CIRCUIT
•  Inspect for continuity between the 4x4 CM connector (vehicle harness-side) and the following vehicle harness-side terminals of motor component:
―  4x4 CM connector A— Motor component (shift motor) terminal C
―  4x4 CM connector B— Motor component (shift motor) terminal C
―  4x4 CM connector C— Motor component (shift motor) terminal F
―  4x4 CM connector D— Motor component (shift motor) terminal F
•  Is there continuity?
Yes
Go to the next step.
No
Repair or replace the wiring harness, then go to next step.
4
VERIFY THAT THE SAME DTC IS NOT PRESENT
•  Reconnect all disconnected connectors.
•  Clear the DTCs from the memory.
•  Change the current transfer mode by operating the 4x4 switch.(2H-4H-4L)
•  Are any DTCs present?
Yes
Repeat the inspection from Step 1.
If the malfunction recurs, replace the 4x4 CM, then go to the next step.
(See 4x4 CONTROL MODULE REMOVAL/INSTALLATION [AT].)
No
Go to the next step.
5
VERIFY THAT NO OTHER DTCS ARE PRESENT
•  Are any DTCs present?
Yes
Go to the applicable DTC troubleshooting.
(See 4x4 CONTROL SYSTEM ON-BOARD DIAGNOSIS [WL-C, WE-C (AT)].)
No
Troubleshooting completed.
