Grand Caravan V6-3.8L VIN L (2007)
Back-up switch - Ground input on pin 39. Input is converted to a PCI Bus status message for use by other modules.
Wiper park switch - Ground input on pin 16. Used to determine park placement of wipers. Also used as feedback to FCM to determine correct
operating mode of wipers.
Washer fluid level switch - Ground input to pull-up on pin 18. Ground is switched into the circuit when washer bottle fluid level is low.
Brake fluid level switch - Ground input to pull-up on pin 36. Ground is switched into the circuit when brake fluid level is low.
Ambient temperature sensor - Resistive input to pull-up on pin 25. Corresponding voltage level is converted to a PCI Bus message for use by other
modules on the bus.
Right park lamp outage - 12 volt input on pin 21. Used to determine if right park lamp circuit is operating properly.
Left park lamp outage - 12 volt input on pin 41. Used to determine if left park lamp circuit is operating properly.
Battery IOD - 12 volt input on pin 20. The FCM enters a low power consumption mode when the ignition is turned OFF. This low current draw
battery supply keeps the microprocessor functioning in the low power mode.
Battery (+) connection detection - 12 volt input on pin 38. The battery connection on the PDC incorporates the use of an internal switch to
determine if the connector is properly mated and the Connector Positive Assurance (CPA) is engaged. If the CPA is not properly engaged, a voltage
on pin 38 will be interpreted as an unseated connector and a fault will set.
NOTE: If the FCM is replaced, ensure connection between the FCM and the PDC is in good condition.
