RAM 2500 Van V8-360 5.9L Magnum (1995)
Key Reminder Relay: Description and 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. The M50 circuit supplies current to the ignition switch lamp and the
headlamp switch lamp. Circuit Z1 provides ground for the lamps. Circuit Z1 terminates at the instrument panel, above the headlamp switch. Circuit Z1
also provides ground for the ash receiver lamp, cigar lighter lamp, and glove box lamp.
