Circuit | Short to Ground | Open/High Resistance | Short to Voltage | Signal Performance |
---|---|---|---|---|
High Clutch Temperature Sensor Circuit | C0394 06 | C0394 06 | -- | -- |
Low Clutch Temperature Sensor Circuit | -- | C0394 06 | -- | -- |
The Rear Differential Clutch Control Module (RDCCM) provides a power and ground circuits to the temperature sensor. When the temperature of the module is determined to be beyond its limits, the RDCCM will temporarily disable the rear drive system.
• | The ignition is ON. |
• | Ignition voltage is greater than 9 volts. |
An open or short to ground is detected on the temperature sensor circuits.
One or more of the following actions may occur:
• | All Wheel Drive Off (AWD Disabled) DIC message. |
• | Service All Wheel Drive (Service AWD) DIC message. |
• | The condition for the DTC is no longer present. |
• | The DTC is not detected in 40 consecutive drive cycles. |

⇒ | If less than the specified value, test the appropriate circuit for a short to ground. If the circuit tests normal, replace the rear differential. |
⇒ | If less than the specified range, test both circuits for an open/high resistance. If the circuit tests normal, replace the rear differential. |
⇒ | If greater than the specified range, test both circuits for an open/high resistance. If the circuit tests normal, replace the rear differential. |
Perform the Diagnostic Repair Verification after completing the diagnostic procedure.
