ILLUMINATION
System DescriptionINFOID:0000000001328422
Control of illumination lamps operation is dependent upon position of lighting switch (combination switch).
When lighting switch is placed in the 1ST or 2ND positi on (or if auto light system is activated), BCM (body con-
trol module) receives input signal requesting illuminati on lamps to illuminate. This input signal is communi-
cated to IPDM E/R (intelligent power distribution module engine room) through the CAN communication. The
CPU (central processing unit) located in the IPDM E/R co ntrols tail lamp relay coil. This relay, when energized,
directs power to illumination lamps, which then illuminate.
Power is supplied at all times
 through 10A fuse (No. 71, located in IPDM E/R)
 to tail lamp relay, located in IPDM E/R, and
 to CPU located in IPDM E/R.
Power is also supplied at all times
 through 50A fusible link (letter M, located in fuse, fusible link and relay box)
 to BCM terminal 55,
 through 15A fuse [No. 22 located in fuse block (J/B)]
 to BCM terminal 42,
 through 15A fuse (No. 78, located in IPDM E/R)
 to CPU located in IPDM E/R,
 through 10A fuse [No. 19 located in fuse block (J/B)]
 to unified meter and A/C amp. terminal 21 and
 to combination meter terminal 8.
With ignition switch in ON or START position, power is supplied
 to ignition relay, located in IPDM E/R, from battery direct,
 through 15A fuse [No. 1 located in fuse block (J/B)]
 to BCM terminal 38,
 through 10A fuse [No. 12, located in fuse block (J/B)]
 to unified meter and A/C amp. terminal 22 and
 to combination meter terminal 7.
With ignition switch in ACC or ON position, power is supplied
 through 10A fuse [No. 6, located in fuse block (J/B)]
 to combination meter terminal 4 and
 to BCM terminal 11.
Ground is supplied
 to BCM terminals 49 and 52
 to unified meter and A/C amp. terminals 29 and 30, and
 to combination meter terminals 5, 6, and 15
 through grounds M35, M45, and M85,
 to IPDM E/R terminals 38 and 60
 through grounds E21, E50, and E51.
ILLUMINATION OPERATION BY LIGHTING SWITCH
With lighting switch in the 1ST or 2ND position (or if auto light system is activated), BCM receives input signal
requesting illumination lamps to illuminate. This input signal is communicated to IPDM E/R through the CAN
communication. The CPU located in the IPDM E/R controls tail lamp relay coil, which, when energized, directs
power
 through IPDM E/R terminal 22
 to glove box lamp terminal 1
 to A/T device (illumination) terminal 11
 to snow mode switch (illumination) terminal 5
 to VDC off switch (illumination) terminal 3
 to clock (illumination) terminal 3

EXTERIOR LAMP BATTERY SAVER CONTROL
When the lighting switch is in the 1ST or 2ND position (or if auto light system is activated), and ignition switch
is turned from ON or ACC to OFF, batte ry saver control function is activated.
Under this condition, illumination lamps remain illuminated for 5 minutes, then illumination lamps are turned
off.
When the lighting switch is turned from OFF to 1ST or 2 ND position (or if auto light system is activated) after
illumination lamps are turned off by battery save r control, and illumination lamps illuminate again.
Exterior lamp battery saver control mode can be changed by the function setting of CONSULT-III.
CAN Communication System DescriptionINFOID:0000000001328423
CAN (Controller Area Network) is a serial communication line for real time application. It is an on-vehicle mul-
tiplex communication line with high data communication s peed and excellent error detection ability. Many elec-
tronic control units are equipped onto a vehicle, and each control unit shares information and links with other
control units during operation (not independent). In CA N communication, control units are connected with 2
communication lines (CAN H line, CAN L line) allowing a high rate of information transmission with less wiring.
Each control unit transmits/receives data but selectively reads required data only.
CAN Communication UnitINFOID:0000000001328424
Refer to LAN-43, "CAN System Specification Chart".

CHECKING CONDITION OF INSTALLATION
 Check installation condition of steering gear assemb ly, front suspension, axle and steering column.
 Check if movement exists when steering wheel is mo ved up and down, to the left and right and to the axial
direction.
 Check if the mounting bolts for steering gear assembly are loose or not. Refer to PS-17
.
CHECKING STEERING WHEEL PLAY
1. Set tires to the straight ahead, start engine, then turn steering wheel to the left and right lightly, and mea-
sure steering wheel movement on the outer circumfe rence 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-5,
"Wheel Alignment Inspection".
1. Set vehicle to the straight direction, chec k if steering wheel is in the neutral position.
2. If it is not in the neutral position, remo ve steering wheel and reinstall it correctly.
3. If the neutral position cannot adjust in the two teeth of steering gear assembly, loosen outer socket lock
nuts of steering outer sockets, then adjust outer so cket by the same amount in the opposite direction.
CHECKING STEERING WHEEL TURNING FORCE
1. Park vehicle on a level and dry surface, set parking brake.
2. Start engine.
3. Bring power steering fluid up to adequate operating te mperature. [Make sure temperature of fluid is
approximately 50 to 80 °C (122 to 176 °F).]
NOTE:
Tires need to be inflated normal pressure.
4. Check steering wheel turning force when steering wheel has been turned 360 ° from neutral position.
NOTE:
Multiply the distance L from the hook of spring balance to the
center of steering wheel by the measurement value with a spring
balance.
5. If steering wheel turning force is out of the specification, check
rack sliding force and relief hydraulic pressure of oil pump.
Regarding relief hydraulic pressure of oil pump, refer to PS-27, "
On-Vehicle Inspection and Service".

 Check the turning torque of steering column with preload gauge (SST). If it is out of the specified value, repair it or replace with new
one.
INSTALLATION
 Refer to "COMPONENTS" for tightening torque. Install in the reverse order of removal.NOTE:
Refer to component parts location and do not reuse non-reusable parts.
 After removing/installing or replacing steering components, check wheel alignment. Refer to FSU-5, "
Wheel
Alignment Inspection".
 After adjusting wheel alignment, adjust neutral position of steering angle sensor. Refer to BRC-8, "
Adjust-
ment of Steering Angle Sensor Neutral Position".
INSPECTION AFTER INSTALLATION
 Check tilt and telescopic mechanism operating range “L1”, “L2” as
shown in the figure.
 Check if steering wheel operation can turn to the end of the left and right smoothly.

dryer. Assemble it to mounting groove of rack.
3. To fit rack Teflon ring on rack, use rack Teflon ring installation tool (SST) from tooth side. Comp ress rim of ring with the tool.
4. Apply recommended grease to rack oil seal. Insert rack oil seal, then insert rack assembly to gear housing assembly.
CAUTION:
 When inserting rack assembly, do not damage retainersliding part. If it is dama ged, replace gear housing assem-
bly.
 When inserting rack assembly, do not damage cylinder
inner wall. If it is damaged, it may cause oil leaks. Replace
gear housing assembly.
 Attach rack oil seal. Both in ner lip and outer lip should
face each other.
a. To avoid damaging inner rack oil seal, wrap an OHP sheet [approximately. 70 mm (2.76 in) × 100 mm (3.94 in) around rack
tooth. Place oil seal on sheet. Then, pull oil seal along with OHP
sheet until they pass the toothed se ction of rack, then remove it.
b. Insert rack oil seal (inner) to piston (rack Teflon ring) position and push retainer to adjust screw side with fingers lightly, and
