Nissan Altima (L32) 2007-2012 Service Manual: Daytime running light system
System Diagram
System Description
The headlamp system for Canada vehicles is equipped with a daytime light control unit that activates the high beam headlamps at approximately half illumination whenever the engine is running. If the parking brake is applied before the engine is started the daytime lights will not be illuminated. The daytime lights will illuminate once the parking brake is released. Thereafter, the daytime lights will continue to operate when the parking brake is applied.
Component Parts Location
1. IPDM E/R E17, E18, E200, E201
2. BCM M16,M17, M18, M19 (view with instrument panel removed)
3. Combination switch M28
4. Combination meter M24
5. Daytime running light relay E228
6. Parking brake switch E35 (coupe with CVT) M73 (with M/T)
7. Parking brake switch E35 (sedan with CVT)
Component Description
After starting the engine with the parking brake released and the lighting switch in the OFF or 1ST position, the headlamp high beam automatically turns on. With the lighting switch in the 2nd position or with autolamps ON, the headlamps function the same as conventional light systems.
OPERATION
The BCM monitors inputs from the parking brake switch and the combination switch to determine when to activate the daytime light system. The BCM sends a daytime light request to the IPDM E/R via the CAN communication lines. The IPDM E/R grounds the daytime light relay which in turn, provides power to the ground side of the RH high beam lamp. Power flows backward throught the RH high beam lamp to the IPDM E/R, through the high beam fuses, through the LH high beam lamp circuit to the LH high beam lamp and on to ground. The high beam lamps are wired in series which causes them to illuminate at a reduced intensity.
