DTC P080A-54: Clutch Position Not Learned - Missing calibration: Action

NOTE:

The rear differential control module performs a calibration routine every 1000 km.
New electric differentials will perform calibrations more frequently during clutch bed-in.
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, perform routine - On Demand Self Test and cycle the ignition
Inspect the rear differential control module and rear differential locking motor connectors for signs of water ingress and pins for damage and/or corrosion
If the fault persists, refer to the appropriate service information and check the rear differential control module circuit to the rear differential locking motor for short circuit to ground, short circuit to power, open circuit, high resistance. Repair circuit as necessary, clear DTCs and retest
If the fault persists, check and install a new rear differential locking motor as necessary, clear the DTCs and retest
If the fault persists, check and install a new rear differential control module
