OVERVIEW
Windshield wiper and washer operation is controlled by the Central Junction Box (CJB) in response to driver inputs and if fitted, signals from the rain/light sensor.
The wiper and washer system comprises:
- Windshield wiper motor and linkage assembly
- Windshield washer jets - located in cowl panel
- Rear window wiper motor
- Rear window washer jet - located in rear spoiler
- Headlamp washer (if fitted)
- Rain/light sensor (if fitted).
The windshield wipers have five operational states:
- Intermittent wipers - vehicles without rain/light sensor
- Automatic wipers - vehicles with rain/light sensor - automatic wipers can be disabled to operate as intermittent via the Instrument cluster (IC) menu.
- Flick wipe
- Windshield wash and wipe
- Slow wipe
- Fast wipe.
The rear window wiper has three operational states as follows:
- Rear window wash and wipe
- Intermittent rear window wipe
- Continuous rear window wipe.
A windshield washer reservoir contains washer fluid which is used by both the front and rear wipers and the headlamp washers (if fitted).
The headlamp washers (if fitted) use a dedicated headlamp washer pump located in the reservoir. The front and rear washers share a single washer pump.
On vehicles with a rain/light sensor, the wipers have an 'Auto' function. The 'Auto' function uses an output from the rain/light sensor to the CJB on a Local Interconnect Network (LIN) bus to provide automatic operation of the windshield wipers. The rain/light sensor is mounted on the inner surface of the windshield and transmits infra-red light to determine the amount of water on the outer surface of the windshield.
