Nissan Altima (L32) 2007-2012 Service Manual: Parking, license plate and tail
lamps
System Diagram
System Description
• BCM (Body Control Module) controls parking, license plate and tail lamps
operation.
• IPDM E/R (Intelligent Power Distribution Module Engine Room) operates parking,
license plate and tail
lamps according to CAN communication signals from BCM.
When the lighting switch is in 1ST position, BCM detects the LIGHTING SWITCH
1ST POSITION ON. The
BCM sends a parking light ON request through the CAN communication lines to the
IPDM E/R. The IPDM E/R
then activates the tail lamp relay which sends power to the parking and
instrument illumination circuits.
EXTERIOR LAMP BATTERY SAVER CONTROL
With the lighting switch (combination switch) in the 2nd position and the
ignition switch is turned from ON or
ACC to OFF, the battery saver feature is activated.
Under this condition, the headlamps remain illuminated for 5 minutes unless the
lighting switch position is
changed. If the lighting switch position is changed, then the headlamps are
turned off.
This setting can be changed by CONSULT-III. Refer to EXL-30, "BATTERY SAVER :
CONSULT-III Function".
