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 ma rker and tail lamps to illuminate. This input signal is
communicated to the IPDM E/R through the CAN communi cation. The CPU located in the IPDM E/R controls
the tail lamp relay coil, which when energized, directs power.
