2. Clear the DTC with the HDS.
3. Turn the ignition switch to LOCK (0), then turn the ignition switch back to ON (II).
4. Check for DTCs with the HDS.
Is DTC 42-1 indicated?
YES -
Go to step 5.
NO -
Intermittent failure, the system is OK at this time.?
5. Turn the ignition switch to LOCK (0).
6. Disconnect the rear differential fluid temperature sensor 2P connector.
7. Turn the ignition switch to ON (II).
8. Check the REAR DIFFERENTIAL FLUID TEMPERATURE SENSOR in the DATA LIST with the HDS.
Is the sensor reading 0 V?
YES -
Replace the rear differential fluid temperature sensor See: Powertrain Management/Transmission Control Systems/Sensors and Switches -
Transmission and Drivetrain/Sensors and Switches - Differential/Differential Temperature Sensor/Switch/Service and Repair.?
NO -
Go to step 9.
9. Turn the ignition switch to LOCK (0).
10. Disconnect SH-AWD control unit connector A (20P).
11. Check for continuity between rear differential fluid temperature sensor 2P connector terminals No. 1 and No. 2.
Is there continuity?
YES -
Repair a short in the wires between rear differential fluid temperature sensor 2P connector terminals No. 1 and No. 2.?
NO -
Go to step 12.
12. Turn the ignition switch to ON (II).
13. Measure the voltage between body ground and rear differential fluid temperature sensor 2P connector terminals No. 1 and No. 2 respectively.
