DTC 57-2

DTC 57-2: Right Clutch Electromagnetic Coil (Short)

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

1. Turn the ignition switch to ON (II).
2. Make sure the HDS communicates with the vehicle and the SH-AWD control unit. If it doesn't, troubleshoot the DLC circuit.
3. Clear the DTC with the HDS.
4. Do the clutch function test with the HDS.
5. Check for DTCs with the HDS. Is DTC 57-2 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 right solenoid 4P connector.
8. Check for continuity between SH-AWD control unit connector terminals B6 and B7.





Is there continuity?

YES - Repair short in the wires between SH-AWD control unit connector terminals B6 and B7.

NO - Go to step 9.

9. Turn the ignition switch to ON (II).
10. Measure voltage between SH-AWD control unit connector terminal B6 and body ground.





Is there battery voltage?

YES - Repair short to power in the wires between SH-AWD control unit connector terminal B6 and the right 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 right solenoid 4P connector.
17. Measure resistance between right solenoid 4P connector terminals No. 1 and No. 2.





Is there 0.45 Ohms or less?

YES - Replace the rear differential right 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.
