| Unexpected operation of the windshield wipers in auto mode, with the engine running and when the windshield appears to be dry or when the driver's door is opened and closed with the ignition set to on |
- Loss of balance in the rain sensor tracks
|
- Using the Jaguar Land Rover approved diagnostic equipment, perform routine - Rain Sensor Calibration
|
| Wipers and washers inoperative |
- Washers inoperative
- Wiper arm(s) incorrectly installed/aligned
- Steering column right multifunction switch internal failure
- Wipers and washers control switch circuit short circuit to ground, short circuit to power, open circuit, high resistance
|
- Listen for washer motor operation. Check and top up washer fluid level. Check and rectify blocked washer circuit. Check for DTCs indicating a wiper/washer circuit fault. Rectify as necessary
- Check the installation/alignment of the wiper arms. Make sure motor/mechanism is not jammed or seized
- Check if the wipers and washers control switch retaining screws are tightened according to specifications. Inappropriately tightened screws might cause steering wheel module failure
- Refer to the electrical circuit diagrams and check the wipers and washers control switch circuit for short circuit to ground, short circuit to power, open circuit, high resistance
