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. Power for the relay is provided on the M1 circuit from the
IOD fuse (fuse 17) in the fuse block.
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/cargo lamp ON 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 key-in-switch halo
lamp. Circuit Z3 provides ground for the lamp.
