Illumination Operation By Lighting Switch

With lighting switch in the 1ST or 2ND position (or if auto light system is activated), BCM receives input signal requesting illumination lamps to illuminate. This input signal is communicated to IPDM E/R across the CAN communication lines. The CPU located in the IPDM E/R controls tail lamp relay coil, which, when energized, directs power
