DTC P18A5-64: Motion/Position Sensor A Signal Circuit - Signal plausibility failure: Action
NOTE:
After installing a new rear differential control module, differential locking motor or electric differential, clear the DTCs and calibrate the system by performing routine - On Demand Self Test.
- Using the Jaguar land Rover approved diagnostic equipment, reconfigure the rear differential control module with the latest level software and perform routine - On Demand Self Test
- Inspect the rear differential control module connector for security, signs of water ingress and pins for damage and/or corrosion
- Refer to the appropriate service information and check the differential locking motor position sensor signal 1 circuit for short circuit to ground, short circuit to power, open circuit, high resistance. Repair the wiring harness as necessary
- Refer to the appropriate service information and check the differential locking motor position sensor signal 2 circuit for short circuit to ground, short circuit to power, open circuit, high resistance. Repair as necessary
- Refer to the appropriate service information and check the differential locking motor circuit for short circuit to ground, short circuit to power, open circuit, high resistance. Repair the wiring harness as necessary
- Using the Jaguar Land Rover approved diagnostic equipment, clear the DTCs and perform routine - On Demand Self Test
- If the fault persists, install a new differential locking motor
- If the fault persists, install a new rear differential control module
