Courtesy Lighting

When the door unlock button on the transmitter is depressed, the remote control door lock receiver provides a ground on CKT 156 (WHT) to turn the courtesy lamps on. This provides courtesy lighting for approximately 30 seconds before timing out. Courtesy lighting can also be cancelled by a KEY ON ignition cycle. The dome lamp defeat switch has no effect on the courtesy lighting that is activated by a remote transmission from the transmitter. The remote control door lock receiver acts in much the same way as the interior lamp control module in that it receives a switched ground signal on CKT 157 (GRY) through the dome lamp defeat switch to CKT 328 (PPL) from the door jamb switches and in turn grounds CKT 156 (WHT) to turn the courtesy lamps on. However if the dome lamp defeat switch is ON the remote control door lock receiver will not see the switched ground signal from the door jamb switches when a door is opened and no courtesy lighting will be activated.
