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 headlamp switch lamp. Power for the relay is
provided on the M11 circuit from the interior lamp defeat switch.
Circuit M2 provides ground for the time delay relay through the door ajar switches, headlamp switch and the power door lock module. 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. Circuit M50 supplies current to the ignition switch key-in halo
lamp and the headlamp switch lamp. Circuit Z1 provides ground for the lamps. Circuit Z1 also provides ground for the cigar lighter lamp, and
glove box lamp.
