Refer to the appropriate system wiring diagrams and check the door blind motor circuit for short circuit to ground, short circuit to power, open circuit, high resistance. Repair circuit as required and reconnect the startup battery ground cable. Operate window blind (up and down) through at least two cycles. Using the Jaguar Land Rover approved diagnostic equipment, clear the DTCs and retest
If fault persists, install a new door blind motor as required
