Grand Caravan V6-3.3L VIN R (2005)
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.
Flash programming voltage - 20 volt input on pin 42. When a DRBIII(R) is connected and the proper flash reprogramming sequence is selected, the 20
volt signal will be applied through pin 42.
