OPERATION BY LIGHTING SWITCH
With the lighting switch in the 1ST or 2ND position (or if the auto light system is activated), the BCM receives
input signal requesting the parking, license plate, side marker and tail lamps to illuminate. This input signal is
communicated to the IPDM E/R through the CAN communication lines. The CPU located in the IPDM E/R
controls the tail lamp relay coil, which when energized, directs power.
