DAYTIME LIGHT SYSTEM
System DiagramINFOID:0000000001527654
System DescriptionINFOID:0000000001527655
The daytime light system operates the front clearance lamps, rear tail lamps and license plate lamps. The
BCM monitors the engine running status and lighting switch (combination switch) signal to determine whether
the daytime light system should be activated. With the engine running and the lighting switch OFF, the BCM
sends a signal via CAN communication to the IPDM E/R (Intelligent Power Distribution Module Engine Room)
to activate the headlamp low relay and the daytime light relay. The IPDM E/R supplies ground to the headlamp
low relay coil and daytime light relay coil which then energize to send power to the low beam headlamps, front
clearance lamps, rear tail lamps and license plate lamps.
