ILLUMINATION CONTROL SYSTEM
System DiagramINFOID:0000000005358668
System DescriptionINFOID:0000000005358669
The illumination lamps operation is dependent upon the posit ion of the combination switch (lighting and turn
signal switch). When the combination switch (lighting and turn signal switch) is placed in the 1ST or 2ND posi-
tion (or if the auto light system is activated) the BCM (body control modul e) receives input requesting the park-
ing 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 s witch) is in the 1ST or 2ND 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 30 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 1ST or 2ND position (or if auto light system is activated) after illumination
lamps have been turned off by the battery saver c ontrol, the illumination lamps illuminate again.

Service NoticeINFOID:0000000005147346
• When removing or installing various parts, place a cloth or padding on the vehicle body to prevent scratches.
• Handle trim, molding, instruments, grille, etc. carefully during removing or installing. Be careful not to soil or
damage them.
• Apply sealing compound where necessary when installing parts.
• When applying sealing compound, be careful that the sealing compound does not protrude from parts.
• When replacing any metal parts (for example body outer panel, members, etc.), be sure to take rust preven-
tion measures.

Precaution for Liquid GasketINFOID:0000000005149020
REMOVAL OF LIQUID GASKET SEALING
• After removing the bolts and nuts, separate the mating surface and
remove the old liquid gasket sealing using Tool.
CAUTION:
Do not damage the mating surfaces.
• Tap the seal cutter to insert it (1).
• In areas where the Tool is difficult to use, lightly tap to slide it (2).
LIQUID GASKET APPLICATION PROCEDURE
1. Remove the old liquid gasket adhering to the gasket application surface and the mating surface using suitable tool.
• Remove the liquid gasket completely from the groove of the
liquid gasket application surface, bolts, and bolt holes.
2. Thoroughly clean the mating surfaces and remove adhering moisture, grease and foreign material.
3. Attach the liquid gasket tube to the Tool. Use Genuine RTV Silicone Sealant or equivalent. Refer to
GI-15, "
Recommended Chemical Products and Sealants".
4. Apply the liquid gasket without breaks to the specified location.
• If there is a groove for the liquid gasket application, apply theliquid gasket to the groove.
• As for the bolt holes, normally apply the liquid gasket inside
the holes. If specified in the procedure, it should also be
applied outside the holes.
• Within five minutes of liquid gasket application, install the mat-
ing component.
• If the liquid gasket protrudes, wipe it off immediately.
• Do not retighten after the installation.
• Wait 30 minutes or more after installation before refilling the engine with engine oil and engine coolant.
CAUTION:
If there are specific instructions in this manual, observe them.
