MODULE NETWORK INPUT MESSAGES

Wiper Activated Headlamps

If equipped with automatic headlamps, the BCM illuminates the exterior lamps within 10 seconds of the windshield wipers being activated by the wiper/washer switch when the headlamp control switch is in the AUTOLAMP position. The BCM continues to illuminate the exterior lamps for approximately 30 seconds after the windshield wipers have been turned off.

If equipped with rain sensitive wipers (feature must be enabled through the message center) and the wiper/washer switch is in one of the 5 auto/intermittent settings, the BCM illuminates the exterior lamps within 30 seconds of the windshield wipers being activated by moisture detected on the windshield when the headlamp control switch is in the AUTOLAMP position. The BCM continues to illuminate the exterior lamps for approximately 60 seconds after the windshield wipers have been deactivated (moisture no longer detected on the windshield).

Speed Dependent Wipers

The speed dependent feature increases the frequency of wiping to compensate for the extra moisture that accumulates on the windshield as the vehicle speed increases. This feature activates when the wiper/washer switch is in any intermittent setting except the INT 1 position. As vehicle speed increases, the speed dependent feature gradually shortens the delay between wipes.

Rain Sensitive Wipers

When equipped, the rain sensitive wiper feature replaces the intermittent wiper feature. There are no interval (intermittent) wipe functions available when the rain sensitive feature is active. The wiper system only wipes when the rain sensing feature detects moisture on the windshield. The rain sensitive feature is active when the wiper/washer switch is in any of the 5 auto/intermittent sensitivity settings. The setting closest to OFF is the least sensitive to moisture, the highest setting being the most sensitive to moisture.

The rain sensor sends data through the LIN to the windshield wiper motor. When the rain sensitive wiper feature is enabled, based on the data received from the rain sensor and the auto/ intermittent setting on the wiper/washer switch, the system automatically activates and adjusts the wiper speed and frequency when moisture is detected on the windshield.

The rain sensitive wiper feature can be enabled/disabled through the message center.

When the rain sensitive wipers are disabled from the message center, or the windshield wiper motor detects a fault with the rain sensor input, the windshield wiper motor changes to a default intermittent mode. The timing of the wipers correspond to a standard intermittent setting based on the auto/ intermittent sensitivity setting on the wiper/washer switch.

When the washer switch on the end of the wiper/washer stalk is pressed, the SCCM sends the request to the windshield wiper motor through the LIN. The windshield wiper motor activates the wash relay (which is internal to the windshield wiper motor) providing voltage to the washer pump and directing washer fluid to the windshield.

Courtesy Wipe

When the windshield washer system is activated, the wipers cycle 3 times with washer fluid, followed by one final wipe a few seconds later to clear any remaining fluid that is dripping from the top of the windshield. This feature can be enabled/disabled through the message center. For additional information on enabling/disabling this feature, refer to the Owner's Literature.

Front Wiper Motor

The windshield wiper motor contains a logic module, a 2-speed motor, 2 relays for wiper operation and one relay for washer operation. The logic module continuously monitors the inputs from the SCCM whenever the ignition is in RUN or ACCESSORY and activates the appropriate relay(s) to achieve the desired driver request.

Wiper/Washer Switch

The wiper/washer switch provides the following inputs to the SCCM for the front wiper/wash functions.

1. AUTO 1/INT 1
2. AUTO 2/INT 2
3. AUTO 3/INT 3
4. AUTO 4/INT 4
5. AUTO 5/INT 5
6. Low
7. High
8. Front washer

On vehicles with the police package, the wiper washer switch is integrated into the multifunction switch.

Washer Pump

The front and rear washer system share the same washer reservoir and a bi-directional washer pump. The pump delivers washer fluid to the windshield when the windshield wiper motor activates the internal washer relay, which provides voltage to the washer pump. Ground for the washer pump is provided through the rear washer relay located in the BJB.

Rain Sensor

The rain sensor optically senses water on the windshield. An infrared beam lights a section of the windshield. The intensity of the reflected beam is measured and compared to the intensity of the transmitted beam. If there is water on the surface of the windshield, the beam distorts, reducing the intensity of the beam. If the beam is not reflected completely, it is interpreted as rain on the windshield and the windshield wipers are activated.

A gel-type lens is used as the interface between the rain sensor and the windshield. If the lens is missing or damaged, the rain sensing wipers can be inoperative. The rain sensor gel-type lens is part of the rain sensor and cannot be replaced separately on a rain sensor of this type.

MODULE NETWORK INPUT MESSAGES

When the wiper/washer switch is placed in the rear WASH position, the SCCM sends the request to the windshield wiper motor through the LIN. The windshield wiper motor grounds the rear washer relay directing washer fluid to the rear window.

Reverse Gear Wipe

When the wiper/washer switch is in any position other than OFF (or moisture is detected on the windshield if equipped with rain sensitive wipers) and the transmission selector lever is placed in the REVERSE position, the rear window wiper activates automatically. This feature can be enabled/disabled through the message center. For additional information on enabling/disabling this feature, refer to the Owner's Literature.

Rear Wiper Motor

The rear window wiper motor contains a logic module, an integrated relay and a single speed motor. The integrated relay is used to both operate and park the motor.

The logic module inside the windshield (front) wiper motor controls the rear window wiper and washer based on the inputs from the SCCM. The logic module controls the coil side of the rear window wiper motor relay and the coil side of the rear washer relay in the BJB.

The wiper/washer switch provides the following inputs to the SCCM for the rear wiper/wash functions.

1. INT 1
2. INT 2
3. Rear washer

The front and rear washer system share the same washer reservoir and a bi-directional washer pump. The pump delivers washer fluid to the rear glass when the windshield wiper motor activates the rear washer relay, which provides voltage to the washer pump. Ground for the washer pump is provided through the washer relay which is internal to the windshield wiper motor.
