INTERIOR ROOM LAMP CONTROL SYSTEM : System Description
OUTLINE
The timer control functions of the BCM activate based on inputs from the key cylinder lock/unlock switch LH, the door switches, the key switch and door lock/unlock switches.
*Interior room lamp and map lamp (when lamp switch is in DOOR position).
ROOM LAMP TIMER OPERATION
When the interior room lamp switch is in the DOOR position and when all conditions below are met, the BCM begins timer control (maximum 30 seconds) for interior room lamp ON/OFF.
Timer control is cancelled under the following conditions.
Interior lamp operational settings can be changed with the function setting of CONSULT.
INTERIOR LAMP BATTERY SAVER CONTROL
If an interior lamp is left ON and does not turn OFF even when the doors are closed, the BCM turns off power to the interior lamps automatically to save the battery 10 minutes after the ignition switch is turned OFF.
The BCM controls power and ground to all interior lamps.
After the battery saver system turns the lamps OFF, the lamps will illuminate again when
The interior lamp battery saver control time period can be changed with the function setting of CONSULT.
Illumination control system
ILLUMINATION CONTROL SYSTEM : System Diagram
ILLUMINATION CONTROL SYSTEM : System Description
The illumination lamps operation is dependent upon the position of the combination switch (lighting and turn signal switch). When the combination switch (lighting and turn signal switch) is placed in the AUTO (if equipped and activated) or parking lamp position the BCM (body control module) receives input requesting the parking lamps to illuminate. This input is communicated to the IPDM E/R (intelligent power distribution module engine room) via the CAN communication lines. The CPU (central processing unit) of the IPDM E/R controls the tail lamp relay coil. When energized, this relay directs power to the parking and illumination lamps, which then illuminate.
BATTERY SAVER CONTROL
When the combination switch (lighting and turn signal switch) is in the AUTO (if equipped and activated) or parking lamp position and the ignition switch is turned from ON or ACC to OFF, the battery saver control feature is activated. Under this condition, the illumination lamps remain illuminated for 10 minutes unless the combination switch (lighting and turn signal switch) position is changed. If the combination switch (lighting and turn signal switch) position is changed, then the illumination lamps are turned off after a 30 second delay.
When the combination switch (lighting and turn signal switch) is turned from OFF to AUTO (if equipped and activated) or parking lamp position after illumination lamps have been turned off by the battery saver control, the illumination lamps illuminate again.

Precautions for Suspension
When installing rubber bushings, the final tightening must be carried
out under unladen conditions with tires
on ground. Spilled oil might shorten the life of rubber bushings. Be sure to
wipe off any spilled oil
Unladen conditions mean that fuel, engine coolant and lubricant are full. ...
