Front Fog Lamps

When the Ignition Switch is in RUN, battery voltage is applied to the coil of Front Fog Lamps Relay "B" from the IGN 1 Fuse. Battery voltage is applied at all times to the switch of Front Fog Lamps Relay "B" from the FOG/DRL Fuse. When the Front Fog Lamp Switch is enabled, terminal D7 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 Front Fog Lamp, RH Front Fog Lamp and the Front Fog Lamps ON Indicator. The PZM also activates the park lamps when the fog lamps are on. If the front fog lamps are enabled and the high beams or Flash-To-Pass are activated, the front fog lamps will be temporarily disabled for as long as the high beams or Flash-To-Pass are enabled. The park lamps will remain on during this period.
