to combination meter terminal 8
With the ignition switch in the ON or START position, power is supplied
to ignition relay, located in the IPDM E/R, and
through 10A fuse (No. 59, located in the fuse and relay box)
to BCM terminal 38, and
through 10A fuse [No. 14, located in the fuse block (J/B)]
to combination meter terminal 24.
Ground is supplied
to BCM terminal 67 and
to combination meter terminal 17
through grounds M57, M61 and M79, and
to IPDM E/R terminals 38 and 59
through grounds E9, E15 and E24.
ILLUMINATION OPERATION BY LIGHTING SWITCH
With the lighting switch in the 1ST or 2ND position (or if the auto light system is activated), the BCM receives
input signal requesting the illumination lamps to illuminate. This input signal is communicated to the IPDM E/R
across the CAN communication lines. The CPU of the IPDM E/R controls the tail lamp relay coil, which, when
energized, directs power

EXTERIOR LAMP BATTERY SAVER CONTROL
When the combination switch (lighting switch) is in the 1ST or 2ND position (or if auto light system is acti-
vated), and the ignition switch is turned from ON or ACC to OFF, the battery saver control function is activated.
Under this condition, the illumination lamps remain illuminated for 5 minutes, then the illumination lamps are
turned off.
When the lighting switch is turned from OFF to 1ST or 2ND position (or if auto light system is activated) after
illumination lamps are turned off by the battery saver control, the illumination lamps illuminate again.
Exterior lamp battery saver control mode can be changed by the function setting of CONSULT-II.

On-Vehicle Inspection and ServiceEGS000UC
CHECKING CONDITION OF INSTALLATION
Check installation condition of steering gear assembly, front suspension, axle and steering column.
Check if movement exists when steering wheel is moved up and down, to the left and right and to the axial
direction.
Check if the mounting nuts for steering gear assembly are loose.
Refer to PS-15, "
POWER STEERING GEAR AND LINKAGE" .
CHECKING STEERING WHEEL PLAY
1. Turn tires straight ahead, start engine, then turn steering wheel to the left and right lightly, and measure
steering wheel movement on the outer circumference when steering wheel is turned up to the point where
tires start moving.
CHECKING NEUTRAL POSITION ON STEERING WHEEL
Check neutral position on steering wheel after confirming that front wheel alignment is correct. Refer to
FSU-6, "
Front Wheel Alignment" .
1. Turn tires straight ahead, check if steering wheel is in the neutral position.
2. If it is not in the neutral position, remove steering wheel and reinstall it correctly.
3. If the neutral position cannot be attained by repositioning the steering wheel two teeth or less on steering stem, loosen tie-rod lock nuts of steering outer sockets, then adjust tie-rods by the same amount in the
opposite direction.
CHECKING STEERING WHEEL TURNING FORCE
1. Park vehicle on a level, dry surface and set parking brake.
2. Start engine.
3. Bring power steering fluid up to operating temperature of 60 ° – 80° C (140 ° – 176° F).
4. Tires need to be inflated to specified pressure. Refer to WT-38, "
Tire" .
5. Check steering wheel turning force using Tool when steering wheel has been turned 360 ° from the neutral position.
6. If steering wheel turning force is out of specification, inspect the following:
Steering column. Refer to PS-11, "INSPECTION AFTER
REMOVAL" .
Power steering oil pump. Refer to PS-21, "CHECKING
RELIEF OIL PRESSURE" .
7. If steering column and power steering oil pump meet specifications, replace steering gear. Refer to PS-15,
"Removal and Installation" .
