DTC No.3	Clutch coil malfunction
DETECTION CONDITION	• Open circuit, short to ground or short to battery has been detected in the clutch coil wiring harness.
POSSIBLE CAUSE	• Open circuit in the wiring harness between 4x4 CM terminal U and clutch coil terminal C, short to battery or to ground • Clutch coil malfunction • Poor connection at connector (female terminal)

Diagnostic procedure

STEP	INSPECTION		ACTION
1	INSPECT CLUTCH COIL • Turn the engine switch off. • Inspect the clutch coil. (See CLUTCH COIL INSPECTION [5R55S].) • Is the clutch coil normal?	Yes	Go to the next step.
1		No	Replace the clutch coil, then go to step 5.
2	INSPECT CLUTCH COIL WIRING HARNESS FOR SHORT TO GROUND • Disconnect the 4x4 CM connector. • Disconnect the clutch coil connector. • Inspect for continuity between the 4x4 CM connector terminal U (vehicle harness-side) and body ground. • Is there continuity?	Yes	Repair or replace the wiring harness, then go to step 5.
2		No	Go to the next step.
3	INSPECT CLUTCH COIL WIRING HARNESS FOR SHORT TO POWER SUPPLY CIRCUIT • Measure voltage between the clutch coil connector terminal C (vehicle harness-side) and body ground. • Is the voltage 1 V or less?	Yes	Go to the next step.
3		No	Repair or replace the wiring harness, then go to step 5.
4	INSPECT CLUTCH COIL WIRING HARNESS FOR OPEN CIRCUIT • Inspect for continuity between the 4x4 CM connector U (vehicle harness-side) and the vehicle harness-side terminal C of clutch coil. • Is there continuity?	Yes	Go to the next step.
4		No	Repair or replace the wiring harness, then go to step 5.
5	VERIFY THAT THE SAME DTC IS NOT PRESENT • Reconnect all disconnected connectors. • Clear the DTCs from the memory. (See 4x4 CONTROL SYSTEM ON-BOARD DIAGNOSIS [WL-C, WE-C (AT)].) • Change the current transfer mode by operating the 4x4 switch.(2H-4H) • 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].)
5		No	Go to the next step.
6	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)].)
6		No	Troubleshooting completed.
