Grand Caravan FWD V6-3.8L VIN L (2001)
Pulse Wipe
When the wiper is in the OFF position and the driver presses the Wash button for more than 0.062 Seconds, but less than 0.5 seconds, 2 wipe
cycles in low speed mode will be provided.
Park After Ignition OFF
Because the wiper relays are powered from the battery, the BCM can run the wipers to park after the ignition is turned OFF.
Wipe After Wash
When the driver presses the wash button for over 0.5 seconds and releases it, the wiper will continue to run for 2 additional wipe cycles.
Rear Wiper
The rear wiper/washer system consists of the following features: mist wipers, intermittent wipers and wipe after wash. The rear wiper system is
only active when the ignition switch is in the RUN/ACC position. The vehicle operator selects the rear wiper function using one of the three
buttons on the dash mounted rear wiper switch. The rear wiper switch is hardwired to the Body Control Module (BCM). Upon receiving a wiper
switch signal, the BCM provides 12 volts to the rear wiper motor. Rear washer occurs when the BCM receives a rear washer switch ON input. The
BCM sends a PCI Bus message to the FCM requesting rear washer ON. The FCM activates the rear washer by providing a ground for the rear
washer motor.
Speed Sensitive Intermittent Wipe Mode
The delay setting of the Rear Wiper system is based solely on the vehicle speed. The delay time is defined as the amount of time from the start of a
wipe to the beginning of the next wipe. The Rear Wiper system delay time is based on the following:
7.75 - (MPH x .05) = Seconds delay
Examples:
At zero (0) MPH the delay is 7.75 seconds.
At 100 MPH the delay is 2.75 seconds.
Wipe After Wash
When the driver presses the wash button for over 1.5 seconds and releases it, the wiper will continue to run for 2 additional wipe cycles.

DRBIII(R) DOES NOT POWER UP (BLANK SCREEN)
If the LED's do not light or no sound is emitted at start up, check for loose cable connections or a bad cable. Check the vehicle battery voltage
(data link connector cavity 16). A minimum of 11 volts is required to adequately power the DRB. Check for proper grounds at DLC cavities 4 and
5.
If all connections are proper between the DRB and the vehicle or other devices, and the vehicle battery is fully charged, an inoperative DRB may
be the result of a faulty cable or vehicle wiring.
