C1482-15

C1482-15-REAR DIFFERENTIAL MOTOR TEMPERATURE SENSOR - CIRCUIT SHORT TO BATTERY OR OPEN





For a complete wiring diagram, refer to the Wiring Information.

- When Monitored:
With the ignition on and no system undervoltage or overvoltage condition present.

- Set Condition:
The Electronic Limited Slip Differential (ELSD) Module detects excessive voltage fluctuation on the Mode Sensor Signal circuit.





1. VERIFY THE DTC IS ACTIVE
1. Ignition on, engine not running.
2. With the scan tool, record and erase DTCs.
3. Cycle the ignition switch from off to on.
4. With the scan tool, read DTCs.

Is the DTC active at this time?

Yes

- Go To 2

No

- Go To 7

2. (T330) TEMPERATURE SENSOR RETURN CIRCUIT SHORTED TO VOLTAGE




1. Turn the ignition off to the lock position.
2. Disconnect the Rear Differential Solenoid harness connector.
3. Disconnect the ELSD C1 harness connector.
4. Measure the voltage of the (T330) Temperature Sensor Return circuit in the Rear Differential Solenoid harness connector.

Is the voltage above 5.5 volts?

Yes

- Repair the (T330) Temperature Sensor Return circuit for a short to voltage.
- Perform the ELSD VERIFICATION TEST. ELSD Verification Test.

No

- Go To 3

3. (T331) TEMPERATURE SENSOR SIGNAL CIRCUIT SHORTED TO VOLTAGE




1. Measure the voltage of the (T331) Temperature Sensor Signal circuit in the Rear Differential Solenoid harness connector.

Is the voltage above 5.5 volts?

Yes

- Repair the (T331) Temperature Sensor Signal circuit for a short to voltage.
- Perform the ELSD VERIFICATION TEST. ELSD Verification Test.

No

- Go To 4

4. (T330) TEMPERATURE SENSOR RETURN CIRCUIT OPEN OR HIGH RESISTANCE




1. Measure the resistance of the (T330) Temperature Sensor Return circuit between the ELSD C1 harness connector and the Rear Differential Solenoid harness connector.

Is the resistance below 5.0 Ohms?

Yes

- Go To 5

No

- Repair the (T330) Temperature Sensor Return circuit for an open or high resistance.
- Perform the ELSD VERIFICATION TEST. ELSD Verification Test.

5. (T331) TEMPERATURE SENSOR SIGNAL CIRCUIT OPEN OR HIGH RESISTANCE




1. Measure the resistance of the (T331) Temperature Sensor Signal circuit between the ELSD C1 harness connector and the Rear Differential Solenoid harness connector.

Is the resistance below 5.0 Ohms?

Yes

- Go To 6

No

- Repair the (T331) Temperature Sensor Signal circuit for an open or high resistance.
- Perform the ELSD VERIFICATION TEST. ELSD Verification Test.

6. ELECTRONIC LIMITED SLIP DIFFERENTIAL (ELSD) MODULE
1. Turn the ignition off to the lock position.
2. Replace the Electronic Limited Slip Differential (ELSD) Motor. Removal.
3. Ignition on, engine not running.
4. With the scan tool, erase DTCs.
5. Cycle the ignition switch from off to on.
6. With the scan tool, read DTCs.

Does the DTC remain active?

Yes

- Replace the Electronic Limited Slip Differential (ELSD) Module. Electronic Limited Slip Differential Control Module - Removal.
- Perform the ELSD VERIFICATION TEST. ELSD Verification Test.

No

- Test complete, the condition or conditions that originally set this DTC are not present at this time.

7. INTERMITTENT WIRING AND CONNECTORS
1. Using the wiring diagram/schematic as a guide, inspect the wiring and connectors.
2. While monitoring the scan tool data relative to this circuit, wiggle test the wiring and connectors.
3. Look for the data to change or for the DTC to reset during the wiggle test.

Were any problems found?

Yes

- Repair as necessary.
- Perform the ELSD VERIFICATION TEST. ELSD Verification Test.

No

- Test complete, the condition or conditions that originally set this DTC are not present at this time.
