Rear Fog Lamps

When the Ignition Switch is in RUN, battery voltage is applied to the coil of Rear Fog Lamps Relay "C" from the IGN 1 Fuse. When the Headlamps, Park Lamps, or Front Foglamps are ON, battery voltage is applied to the switch of Front Fog Lamps Relay "B" from the RT PARK Fuse. When the Rear Fog Lamp Switch is enabled, terminal C8 of Instrument Panel Cluster (IPC) connector C3 is grounded through the Headlamp Switch. In response to this input, the IPC sends a request via the Class 2 serial data line to the PZM to activate the front fog lamps. The PZM provides ground for the coil. The coil is energized closing the switch contacts. Voltage is then applied to the LH Rear Fog Lamp, RH Rear Fog Lamp and the Rear Fog Lamps ON Indicator.
