Seat Belt Reminder Lamp: Description and Operation
The seat belt indicator lamp is pulled to ground through an open collector transistor located in the passive restraint control module (PRCM). When the
lamp is switched to ground, ignition voltage flows through the lamp, allowing it to illuminate. This indicates to the vehicle's operator that the shoulder
belt is not buckled, or there is a problem with the passive restraint system.
The seat belt indicator lamp is illuminated, for approximately two seconds, during engine start-up by the PRCM for a bulb check.
