PRINCIPLES OF OPERATION

Turn Signals
When the multifunction switch is placed in the LH or RH TURN position, voltage is routed to the turn lamps. The lighting control module (LCM) flashes the turn lamps at approximately 80 times per minute if both the front and rear turn lamps operate correctly. If only an individual turn lamp operates, the LCM flashes the remaining turn lamp approximately 160 times per minute.

Cornering Lamps
The cornering lamps are supplied voltage from the parking lamp circuit. The multifunction switch provides a ground path for the respective cornering lamp when the turn signal is in the LH or RH TURN position. When the turn signal is activated and the parking lamps are on, the cornering lamp illuminates on the turn side and remains illuminated until the turn signal cancels.

Hazard Lamps
When the hazard switch is engaged, the LCM flashes all the turn lamps at approximately 80 times per minute.
