DTC U2000-4B: Motor Temperature - Over temperature: Action
NOTE:
- This DTC is set when the rear differential actuator temperature exceeds 150°C
- If P0605-00 is also set, perform the relevant corrective action(s) first
- Refer to the appropriate system wiring diagrams and check the rear differential actuator temperature sensor circuit for short circuit to ground, short circuit to power, open circuit, high resistance
- Using the manufacturer approved diagnostic system, clear the DTCs and retest. If the fault persists, install a new rear differential control module
