Caravan FWD V6-3.3L VIN 3 Flex Fuel (2001)
Setting The Variance
Variance is the difference between magnetic north and geographic north. To determine the variance for the area you are in, refer to the following
zone map provided. The number shown for your area is the variance number for your area.
1. Set the compass/mini-trip console (CMTC) to compass/temperature mode.
2. Press and hold down the RESET button for 5 seconds. NOTE: If the button is held for 10 seconds instead of 5, the CMTC will set the variance
to 8 and enter the fast calibration mode.
3. The VAR light will come ON and the last variance setting will be displayed.
4. Press the STEP button to set the zone number.
5. Press the US/M button and resume normal operation.
NOTE: DO NOT ATTACH ANY MAGNETIC DEVICE SUCH AS A MAGNETIC CB ANTENNA TO THE VEHICLE. THIS CAN
CAUSE THE COMPASS TO GIVE FALSE READINGS.
POWER DOOR LOCK SYSTEM
When the BCM receives input for a lock request from a door lock switch, RKE or cylinder lock switch (only with VTSS), it will turn the lock
driver on for a specified time of 375 msec. If the request is there beyond 375 msec, the BCM considers the door lock signal stuck. Once a door
lock or unlock signal is stuck for longer than 10 seconds, the BCM will set a trouble code and the signal input is ignored until the stuck condition
disappears. The door lock switches provide a variable amount of resistance thereby dropping the voltage of the multiplexed (MUX) circuit and the
BCM will respond to that command.
Sliding Door Memory Lock
When the BCM receives an input for a lock request and a sliding door is open, the BCM will turn ON the lock driver as described above, and will
turn it ON again when all sliding doors are closed. NOTE: If the BCM receives an unlock input before a sliding door is closed, this will cancel the
memory lock.
Door Lock Inhibit
When the key is in the ignition and in any position and either front door is open, the door lock switches LOCK functions are disabled. The
UNLOCK functions are still functional. This protects against locking the vehicle with the keys still in the ignition. The RKE key fob will still lock
the doors as usual. This allows the driver to lock the vehicle with the engine running for warm up.
Automatic Door Locks
This feature can be enabled or disabled by using either the DRBIII(R) or the customer programming method. When enabled all the doors will lock
when the vehicle reaches a speed of 18 MPH (29 KMH) and all the doors are closed. If a door is opened and the vehicle slows to below 18 MPH
(29 KMH), the door locks will operate again once all doors are closed and the speed is above 15 MPH (24 KMH).
Remote Keyless Entry (RKE)
The body control module interfaces with the RKE module via a one-way serial bus interface. The RKE module is not on the PCI bus. The RKE
module sends a 0 - 5 volt pulse width signal to the BCM depending on which button on the transmitter was pressed. The BCM controls the door
lock/unlock functions and the arming/disarming of the Vehicle Theft Security System (if equipped) and the activation of illuminated entry. The
BCM will also send the appropriate messages to the Power Sliding Doors and Power Liftgate modules. The Intelligent Power Module (IPM)
activates the park lamps, headlamps, and horn for horn chirp when sent the appropriate message from the BCM as received from the RKE
transmitter. When a one-button press is made for unlock, both driver side doors will unlock and the front and rear turn signal will flash. When a
second press is initiated (within 5 seconds of the first) both passenger doors will unlock and all four turn signals will flash.
The RKE module is capable of retaining up to 4 individual access codes (4 transmitters). If the PRNDL is in any position except park, the BCM
will ground the interface thereby disabling the RKE.
Both the 3 and 6 buttons transmitters will have 2-CR2016 batteries in series. The minimum battery life should be approximately 4.7 years based
on 20 transmissions a day at 84 °F (25 °C). Using the DRBIII(R) and selecting RKE FOB Test can test the transmitter.
The RKE module can be programmed via the DRBIII(R) or the customer programming method. The BCM will only allow programming mode to
be entered when the ignition is in the on position, the PRNDL is in park position, and the VTSS (if equipped) is in the disarmed mode.
