Accessory Delay Relay: Description and Operation
The accessory relay works in conjunction with the FCM's power accessory delay feature to control the operation of the radio, power windows,
washer motors, wiper motors and power outlet. The accessory relay is turned ON through low side control on pin 35 of the FCM. This circuit is
electronically controlled and continuously monitored for malfunctions. Depending on the ignition switch position, the accessory relay will remain
ON or will time-out and turn OFF. The accessory relay remains ON in the RUN and ACCY positions of the ignition switch. In the UNLK and OFF
positions, the relay will remain energized for 45 seconds then turn OFF. During this time-out period, if the driver or passenger doors are opened,
the relay will turn OFF immediately while the ignition switch is in the START position, the relay will also drop-out, then resume operation.
Accessory relay operation is most noticeable by observing the operation of the radio or blower functions.
