1 Scrivet 2 Windshield washer feed pipe to washer jets 3 Reservoir cap 4 Reservoir filler neck 5 Captive nut (2 off) 6 Headlamp powerwash feed pipe to telescopic washer jets 7 Screw and washer (2 off) 8 Grommet 9 Washer fluid level sensor 10 Windshield washer pump 11 Headlamp washer pump 12 Location spigot The washer reservoir is located in the RH wheel arch. The reservoir is a plastic moulding and is secured in the wheel arch with 2 screws and washers and a scrivet. A level sensor is located in the reservoir and is connected to the CJB. The reservoir is fitted with a washer pump which supplies pressurized washer fluid to the windshield washer jets mounted on the wiper arms.

A vehicle fitted with optional headlamp washers is fitted with a larger reservoir and an additional pump for the headlamp
washers. The larger reservoir is identifiable by a letter 'B' moulded on the casing and has a capacity of 5.5 liters. Reservoirs
moulded with the letter 'A' are for use on vehicles with windshield washers only and have a capacity of 4.4 liters.
A filler cap is located at the top of the reservoir and is accessible from the engine compartment.

The pumps are located in rubber sealing grommets in holes in the reservoir and secured with clips. The pump fluid hoses have
quick release connectors which mate with the pumps. The fluid level sensor is a push fit into a sealing grommet in one side of
the reservoir body.

HEADLAMP POWERWASHERS (if fitted)



Item Description 1 Powerwash trim cap 2 Washer jets 3 Self-tapping screws (2 off) 4 Pressure feed from powerwash pump 5 Telescopic arm

On vehicles with headlamp powerwash, each headlamp assembly is fitted with a headlamp powerwasher. The powerwasher is
located on the underside of the headlamp assembly. The powerwasher is located in a clip at the front of the headlamp and
secured with 2 self tapping screws to the headlamp body.

The powerwasher is a telescopic unit which extends forwards from the headlamp assembly under washer fluid pressure
supplied by the headlamp powerwash pump. When the pump pressure decreases the powerwasher is automatically retracted
back into the housing. The outer end of the powerwasher is fitted with a trim which blends the powerwasher into the headlamp
when it is not operating. The powerwasher has two washer jets which direct washer fluid under high pressure onto the
headlamp lens when the powerwasher is extended.

RAIN/LIGHT SENSOR



The rain/light sensor is located at the upper edge of the windshield, behind the interior rear view mirror. Contact between the
rain sensor and windscreen is provided via a silicon pad which is compressed during the assembly process by two locking
retaining clips either side of the sensor.
The rain/light sensor unit attaches to the windshield via two clips, which latch onto formed tags on the windshield bracket.

The sensor provides information to the CJB for the optimum wiper operation for the prevailing conditions to maintain the shield in a clear condition at all times. The rain/light sensor is an optical unit, which operates on an infrared waveband. The sensor
uses the principle of the laws of reflection on interfacing surfaces between materials with differing refraction properties.

The rain/light sensor is connected to the CJB via a LIN bus. The sensor also receives a hardwired power and ground from the CJB. The 'auto' wipers are activated when the column stalk is moved to position 1 (first position from off in the upward direction). The sensitivity of the sensor can be adjusted by rotating the sensitivity collar on the wiper column stalk in the
clockwise or counterclockwise direction. Clockwise rotation will decrease sensitivity, while counterclockwise adjustment will
increase sensitivity. An increase in sensitivity adjustment results in a single wipe of the front wiper motor.


NOTE: The rain sensor also contains a light sensor. The light sensor is used to control operation of the automatic
headlamps function.
Refer to: Exterior Lighting (417-01 Exterior Lighting, Description and Operation).
WIPER CONTROL SWITCH

The wiper control switch is located on the RH steering column multifunction switch. The switch allows selection of the following functions:

Slow wipe
Fast wipe
Auto
Flick wipe
Windshield wash and headlamp powerwash (if fitted).

All wiper functions are connected to the instrument cluster by a resistor or series of resistors within the switch. The instrument
cluster uses the returned current to determine the selected function.

WIPER SERVICE POSITION

The wiper service position allows the wipers to be parked in a position to allow easy access to the wiper blades for
replacement. The service position is initiated by pulling the RH steering column multifunction switch towards the steering wheel and pressing the start/stop button to switch on the ignition. The wipers will move and stop in a vertical position on the
windshield. The RH steering column multifunction switch can be released and the ignition switched off. The service position is terminated at the next ignition on cycle and the wipers return to their normal park position.

manual. REFER to: (501-16 Wipers and Washers)

Inspection and Verification


CAUTION: Diagnosis by substitution from a donor vehicle is NOT acceptable. Substitution of control modules does not
guarantee confirmation of a fault, and may also cause additional faults in the vehicle being tested and/or the donor vehicle.
1. Verify the customer concern.
2. Visually inspect for obvious signs of damage and system integrity.

3. If an obvious cause for an observed or reported concern is found, correct the cause (if possible) before proceeding to
the next step.
4. If the cause is not visually evident, check for Diagnostic Trouble Codes (DTCs) and refer to the DTC Index.

DTC Index


CAUTION: When probing connectors to take measurements in the course of the pinpoint tests, use the adaptor kit, part
number 3548-1358-00.
NOTES:


If the control module or a component is suspect and the vehicle remains under manufacturer warranty, refer to the
Warranty Policy and Procedures manual (section B1.2), or determine if any prior approval programme is in operation, prior to
the installation of a new module/component.


Generic scan tools may not read the codes listed, or may read only five digit codes. Match the five digits from the scan
tool to the first five digits of the seven digit code listed to identify the fault (the last two digits give additional information
read by the manufacturer approved diagnostic system).


When performing electrical voltage or resistance tests, always use a digital multimeter (DMM) accurate to three decimal
places, and with an up-to-date calibration certificate. When testing resistance, always take the resistance of the DMM leads
into account.


Check and rectify basic faults before beginning diagnostic routines involving pinpoint tests.


Inspect connectors for signs of water ingress, and pins for damage and/or corrosion.


If DTCs are recorded and, after performing the pinpoint tests, a fault is not present, an intermittent concern may be the
cause. Always check for loose connections and corroded terminals.
