DTC 53-1

DTC 53-1, 53-3: Left Clutch Electromagnetic Coil Malfunction

NOTE: Before you troubleshoot, review the general troubleshooting information.

1. Turn the ignition switch ON (II).
2. Clear the DTC with the HDS.
3. Do the clutch function test with the HDS.
4. Check for DTCs with the HDS.

Is DTC 53-1 or 53-3 indicated?

YES - Go to step 5.

NO - Intermittent failure, the system is OK at this time.

5. Turn the ignition switch OFF.
6. Disconnect SH-AWD control unit connector B (8P) and the left solenoid 4P connector.
7. Connect a jumper wire between left solenoid 4P connector terminal No. 1.





8. Check for continuity between SH-AWD control unit connector terminal B5 and body ground.





Is there continuity?

YES - Go to step 9.

NO - Repair open in the wires between the SH-AWD control unit and the left clutch electromagnetic coil.

9. Remove the jumper wire from the left solenoid 4P connector terminal No. 1.
10. Connect a jumper wire between left solenoid 4P connector terminal No. 2.





11. Check for continuity between SH-AWD control unit connector terminal B4 and body ground.





Is there continuity?

YES - Go to step 12.

NO - Repair open in the wires between the SH-AWD control unit and the left clutch electromagnetic coil.

12. Remove the jumper wire from the left solenoid 4P connector terminal No. 1.
13. Reconnect all connectors.
14. Turn the ignition switch ON (II).
15. Check the REAR DIFFERENTIAL FLUID TEMPERATURE in the DATA LIST is above 68°F (20°C) with the HDS before proceeding to the next step. If the temperature is below 68°F (20°C) drive the vehicle to warm up the rear differential until the fluid temperature becomes above 68°F (20°C).
16. Turn the ignition switch OFF.
17. Disconnect the left solenoid 4P connector.
18. Measure the resistance between left solenoid 4P connector terminals No. 1 and No. 2.





Is there 1.8 Ohms or more?

YES - Replace the rear differential left side case.

NO - Update the SH-AWD control unit if it does not have the latest software or substitute a known-good SH-AWD control unit and recheck. If the symptom/indication goes away with the updated SH-AWD control unit, troubleshooting is complete. If the symptom/indication goes away with a known-good SH-AWD control unit, replace the original SH-AWD control unit.
