Lighting System Indicators

Fog Lamp
The IPC illuminates the fog lamp indicator when the malfunction relay K134 detects that the fog lamps are requested (signal is low) from the multifunction relay K134.

Headlamp On Required
The IPC illuminates the headlamp on required indicator when the ambient light sensor detects it is dark enough outside that the headlamps and/or other exterior lamps are required. The BCM sends a hardwire (signal is low) output to the IPC.

High Beam
The IPC illuminates the high beam indicator when the Body Control Module (BCM) detects that the high beams are requested (signal is low).

Turn Signals
The IPC illuminates the right or left turn signal indicator when the IPC detects a turn signal request or a hazard request.
