Lighting System

High Beam
The IPC illuminates the high beam indicator when the high beams are on or the flash to pass feature is activated. The IPC receives a discrete input from the headlamp dimmer switch requesting illumination.

Turn Signals
The IPC illuminates the right or left turn signal indicator when a turn signal or a hazard request is received. The IPC receives a discrete input from the turn signal switch requesting illumination. If the BCM determines that the turn signal is active for more than 1.2 km (0.75 mi), the BCM activates the audible warning.

Malfunction Indicator Lamp (MIL)
The PCM illuminates the MIL (service engine soon or check engine) when the following occurs:
^ The PCM detects a malfunction in the emissions system.
^ The PCM performs the displays test at the start of each ignition cycle. The indicator illuminates for approximately 3 seconds.
^ The ignition is on, with the engine off.
