Grand Caravan FWD V6-3.3L VIN 3 Flex Fuel (2002)
DIAGNOSTIC FEATURES
The PLG an be flashed on vehicle via PCI bus with a DRRBIII(R) diagnostic tool. The DRBIII(R) can read all inputs, actuate all outputs, read module
information and read diagnostic trouble codes. As a reminder, some DTC's can be set during normal PLG operation.
SYSTEM INHIBITORS
1. Battery voltage too high or too low (above 16V, below 9.5 V
2. Vehicle in gear
3. Vehicle speed > 0 mph/km/h
4. Outside temperature too high, above 143 °F (62 °C) or too low, below -12 °F (-24 °C).
5. O/H console lockout will inhibit the B pillar switches only.
6. Liftgate locked will inhibit all interior switches from opeing (overhead console). A locked liftgate can e power closed.
7. Pinch Sensor switch stuck shall inhibit the power do e feature.
Power Sliding Door System
POWER SLIDING DOOR SYSTEM
The Power Sliding Door (PSD) system is activated through the use of the following: Remote Keyless Entry (RKE), overhead console switches, B
pillar switches or the DRBIII(R). These inputs are hardwired to the body control module (BCM) and can be monitored with a diagnostic tool. The
BCM will send the message via PCI bus to the power sliding door module (PSDM). The sliding door must be in the full open or full closed position to
operate. Once the BCM sends a button activation message to the PSDM, the module shall read all inputs, outputs and vehicle conditions to determine
whether it shall open, close or inhibit the PSD operation. During an opening or closing cycle, the PSDM can detect an obstacle present should it meet
sufficient resistance by the hall effect sensors (integrated in the drive motor).
During an open cycle, multiple door activations (RKE, overhead console, B pillar) are ignored until the door reaches the full open position. However,
during a close cycle, a 2nd door activation (RKE, overhead console, B pillar) will reverse the door to the full open position.
If the engine is cranked during a power open/close the PSD will pause then resume after engine cranking. In addition, if the vehicle is placed in gear
during an open cycle, the PSD shall reverse direction and begin closing. If the vehicle is placed in gear during a closing cycle, the PSD shall continue
closing until fully closed.
If the inside or outside handle is activated during an open or close cycle, the PSD will become a full manual sliding door. The child lockout is
mechanical only and has no effect on the B-pillar switch as it did in previous models.
There is only one part number for the power sliding door module (PSDM). The driver sliding door harness has an additional ground circuit which will
identify it as the driver side. This eliminates the need for a left and a right side module.
DIAGNOSTIC FEATURES
The PSDM can be flashed on vehicle via PCI bus with a DRBIII(R) diagnostic tool. The DRBIII(R) can read all inputs, actuate all outputs, read
module information, and read diagnostic trouble codes. As a reminder, some DTC's can be set during normal PSD operation.
SYSTEM INHIBITORS
1. Battery voltage too high or too low (above 16 V, below 9.5 V)
2. Vehicle in gear
3. Vehicle speed > 0 mph/km/h
4. O/H console lockout will inhibit the B pillar switches
5. Doors locked will inhibit all interior switches from opening (Overhead Console, B Pillar). A locked sliding door can be power closed.
Rear Window Defog/Heated Mirror/Front Wiper De-Ice
REAR WINDOW DEFOG/HEATED MIRROR/FRONT WIPER DE-ICE (IF EQUIPPED)
The defroster button located on the HVAC control controls the rear window defogger, heated side view mirrors and front wiper de-icer grid. In
addition the front wiper de-ice function is turned on when front defog/defrost mode is selected.
When the defroster button is pushed, the HVAC control sends a bus message over the PCI bus to the Front Control Module (FCM) which controls the
Rear Window Defogger relay. The defroster LED will illuminate when the defroster function is on. The defroster will function for 10 minutes or can
be cycled off sooner by pressing the defroster button again. The front wiper de-icer grid receives its 12 volts from the accessory relay through fuse 11
and the HVAC control module supplies the grid ground.
Vehicle Theft Security System (VTSS)
VEHICLE THEFT SECURITY SYSTEM
The Vehicle Theft Security System (VTSS) is part of the Body Control Module (BCM). The BCM monitors the vehicle doors, liftgate (export only),
hood (export only), and the ignition for unauthorized operation. The alarm activates by sounding the horn, flashing the headlamps and the VTSS
indicator lamp. The VTSS does not prevent engine operation, this is done with the Sentry Key Immobilizer Module (SKIM). The VTSS indicator
lamp will flash for approximately 15 seconds during the arming process. If there is no interruption during the arming process, upon completion the
VTSS indicator lamp will flash at a slower rate. When the BCM receives an input to trigger the alarm, the BCM will control the outputs of the
