Remote Keyless Entry Exterior Lamp Illumination

WARNING: This page is about a different car, the 2002 Oldsmobile Aurora. However, it is still accessible from the selected car via links, so may be relevant.

When the remote control door lock receiver (RCDLR) module receives a door UNLOCK command from the remote function actuator transmitter, the RCDLR will send a class 2 message to the dash integration module (DIM). The DIM must have inputs that indicate that the ignition switch is OFF, all the doors are closed, and the ambient light sensor is indicating low light conditions. The DIM will then activate the headlamp relay and park lamp relay. The DIM will flash the headlamps and park lamps twice, then keep them on approximately 25 seconds or until a door is opened. When the RCDLR receives a door LOCK command from the remote function actuator transmitter, The DIM will flash the headlights and park lights once. In daylight conditions, the DIM will activate the park lamp relay only to flash the park lamps twice with a door UNLOCK command and once with a door LOCK command from the remote function actuator transmitter.
