Grand Cherokee 2WD V8-4.7L VIN N (2000)
3. Lock the doors with the power lock switch or the RKE.
4. Close the driver's door.
NOTE: AFTER THE DOORS ARE CLOSED, LOCKING THE DOORS WITH RKE WILL ALSO ARM THE SYSTEM.
NOTE: IF THE VTSS INDICATOR LAMP FLASHED, THE SYSTEM IS OPERATIONAL AND VERIFIED. IF NOT, THERE MAY BE A
PROBLEM WITH THE SYSTEM.
Arming/Disarming - Active arming occurs when the remote keyless entry transmitter is used to lock the vehicle doors, whether the doors are open
or closed. If one or more doors are open, the arming sequence is completed only after all doors are closed.
Passive disarming occurs upon normal vehicle entry (unlocking driver's door with the key). This disarming also will halt the alarm once it has been
activated.
Active disarming occurs when the remote keyless entry transmitter is used to unlock the vehicle doors. This disarming also will halt the alarm once
it has been activated.
System Self-Tests - NOTE: System self-tests can be entered only with the DRBIII (R).
NOTE: A POWERTRAIN CONTROL MODULE FROM A VEHICLE EQUIPPED WITH A VEHICLE THEFT SECURITY SYSTEM
CANNOT BE USED IN A VEHICLE THAT IS NOT EQUIPPED WITH A VEHICLE THEFT SECURITY SYSTEM. IF THE VTSS
INDICATOR LAMP COMES ON AFTER IGNITION ON AND STAYS ON, THE PCI BUS COMMUNICATION WITH THE POWERTRAIN
CONTROL MODULE POSSIBLY HAS BEEN LOST.
WINDSHIELD WIPER & WASHER
Front Wiper
System Description
The front wiper system consists of the following features: lo-hi-speed, mist wipers, intermittent wipers, and wipe after wash. The front wiper
system is only active when the ignition is in the run/acc position.
The BCM controls the front wiper system with one low-going output to a relay. With this output the BCM determines the motor wipe rate. This
rate is a function of the intermittent wiper switch position and vehicle speed. The BCM times the delay after the wipers have parked. If the driver
goes from a longer to a shorter delay interval, a wipe is done immediately. The speed sensitive delay is set based on the current speed of the
vehicle. If the vehicle crosses above the speed threshold of 10 MPH (16 KPH) while the intermittent wiper delay is occurring, a smaller delay can
be used. If the vehicle crosses below the speed threshold a longer delay should not be used until the current delay is completed.
In the lo-hi and mist state, the BCM constantly outputs an active control signal for a delay of zero. The multifunction switch controls the wiper
high/ low relay wiper motor in the hi state. This is done with an additional output from the multifunction switch to a relay which selects the motor
winding to be energized. The BCM does not distinguish between lo-hi-or mist positions. The mist position is a momentary input to the BCM
which causes the wipers to operate at low speed as long as the mist input is present.
The BCM also monitors the front washer motor to perform wipe after wash. The BCM will perform 3 wipes after the wash input is released.
Since the front wiper system is an important safety feature, the BCM will support wiper operation in the event of a failed park input.
If BCM does not detect a change of state on the park input for 8 seconds with the wiper relay energized a Diagnostic Trouble Code will set in the
BCM.
Once a failed park switch is detected, intermittent operation is disabled and the BCM will default to the low speed wiper state when the wiper
switch is in the intermittent position. The wiper relay will be de-energized when the wiper mode switch is in the OFF position. For open and short
states on the wiper mode switch, the wipers should default to OFF.
System Features
Speed Sensitive Intermittent Wipe Mode
There are 5 individual delay times with a minimum delay of 1/2 second to a maximum of 18 seconds. When the vehicle speed is under 10
MPH (16 KPH), the delay time is doubled providing a range of 1 second to 36 seconds.
Mist Wipe
The wiper operates as long as the wiper switch is in the mist position.
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 and then releases it, the wiper will continue to run for 3 additional wipe cycles.
