SH-AWD DTC Troubleshooting: 53-2

DTC 53-2: Left Clutch Electromagnetic Coil (Short)

NOTE: Before you troubleshoot, review the general troubleshooting information. Initial Inspection and Diagnostic Overview

1. Turn the ignition switch to ON (II).

2. Make sure the HDS communicates with vehicle and the SH-AWD control unit. If it doesn't, troubleshoot the DLC circuit. Testing and Inspection

3. Clear the DTC with the HDS.

4. Do the clutch function test with the HDS. The SH-AWD Indicator Does Not Come On

5. Check for DTCs with the HDS.

Is DTC 53-2 indicated?
YES - Go to step 6.

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


6. Turn the ignition switch to LOCK (0).

7. Disconnect SH-AWD control unit connector B (8P) and the left solenoid 4P connector.

8. Check for continuity between SH-AWD control unit connector terminals B4 and B5.

Is there continuity?
YES - Repair short in the wires between SH-AWD control unit connector terminals B4 and B5.

NO - Go to step 9.






9. Turn the ignition switch to ON (II).

10. Measure voltage between SH-AWD control unit connector terminal B4 and body ground.

Is there more than 0.5 V?
YES - Repair short to power in the wires between SH-AWD control unit connector terminal B4 and the left clutch electromagnetic coil.

NO - Go to step 11.






11. Turn the ignition switch to LOCK (0).

12. Reconnect all connectors.

13. Turn the ignition switch to ON (II).

14. 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).

15. Turn the ignition switch to LOCK (0).

16. Disconnect the left solenoid 4P connector.

17. Measure resistance between left solenoid 4P connector terminals No. 1 and No. 2.

Is there 0.45 Ohms or less?
YES - Replace the rear differential left side case. Rear Differential Side Case Replacement

NO - Update the SH-AWD control unit if it does not have the latest software, SH-AWD Control Unit Update or substitute a known-good SH-AWD control unit Service and Repair 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. Service and Repair
