Dakota 2WD V6-239 3.9L Magnum (1996)
Key Reminder Relay: Description and Operation
CIRCUIT OPERATION
The time delay relay is used to allow a time-ON function for the ignition switch lamp and the courtesy lamp. Power for the relay is received on the
M1 circuit from the IOD fuse in cavity 2 in the Power Distribution Center (PDC).
Circuit M2 provides ground for the time delay relay through the right and left door jamb switches and the headlamp switch. When a door is
opened or the headlamp switch is moved to the dome lamp position, a ground path is provided for the relay on circuit M2. This energizes the relay,
causing the contacts to close.
When the relay contacts close, power is provided through the relay to circuit M50. The M50 circuit supplies current to the ignition key-in switch
lamp and the courtesy lamp. Circuit Z1 provides ground for the lamps. Circuit Z1 also provides ground for the ash receiver lamp and the cigar
lamp.
