DAYTIME LIGHT OPERATION
With the engine running, the lighting switch in the OFF or AUTO position (headlamp is not illuminate) and
parking brake released, the IPDM E/R receives input request signal from BCM to turn on daytime light. This
input is communicated across the CAN communication lines. The CPU of the IPDM E/R controls the daytime
light relay coil. When energized, this relay directs power
through daytime light relay terminals 5 and 3
through front combination lamp RH terminal 2
through front combination lamp RH terminal 6
through IPDM E/R terminal 27
through 10A fuse (No. 72, located in IPDM E/R)
through 10A fuse (No. 74, located in IPDM E/R)
through IPDM E/R terminal 28
to front combination lamp LH terminal 6.
Ground is supplied
to combination lamp LH terminal 2
through grounds E22 and E43.
With power and grounds supplied, the daytime lights illuminate. The high beam headlamps are now wired in
series and illuminate at a reduced intensity.
COMBINATION SWITCH READING FUNCTION
Refer to BCS-3, "COMBINATION SWITCH READING FUNCTION" .
AUTO LIGHT OPERATION
For auto light operation, refer to LT- 11 5 , "System Description" .
CAN Communication System DescriptionNKS004HQ
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 speed 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 CAN 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 UnitNKS004HR
Refer to LAN-50, "CAN System Specification Chart" .

STEERING WHEELPFP:48430
On-Vehicle Inspection and ServiceNGS000D8
CHECKING CONDITION OF INSTALLATION
Check installation conditions of steering gear assembly, front suspension assembly, axle and steering col-
umn assembly.
Check if movement exists when steering wheel is moved up and down, to the left and right and to the axial
direction.
Check steering gear assembly mounting bolts and nut for looseness. Refer to PS-19, "COMPONENTS" .
CHECKING STEERING WHEEL PLAY
Turn steering wheel so that front wheels come to the straight-ahead position. Start engine and lightly turn
steering wheel to the left and right until front wheels start to move. Measure steering wheel movement on
the outer circumference.
When the measurement value is outside the standard value, check backlash for each joint of steering col-
umn assembly and installation condition of steering gear assembly.
CHECKING NEUTRAL POSITION STEERING WHEEL
Make sure that steering gear assembly, steering column assembly and steering wheel are installed in the
correct position.
Perform neutral position inspection after wheel alignment. Refer to FSU-6, "Wheel Alignment Inspection"
(2WD), FSU-24, "Wheel Alignment Inspection" (AWD).
Set vehicle to the straight-ahead position and confirm steering wheel is in the neutral position.
Loosen outer socket lock nut and turn inner socket to left and right equally to make fine adjustments if
steering wheel is not in the neutral position.
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 temperature. [Make sure temperature of fluid is
approximately 50 to 80°C (122 to 176°F).]
4. Check steering wheel turning force when steering wheel has
been turned 540° 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-30,
"CHECKING RELIEF OIL PRESSURE" .
a. Disconnect lower joint and steering knuckle from steering gear assembly. Refer to PS-13, "
COMPO-
NENTS" , FAX-5, "COMPONENT" .
b. Start and run engine at idle to make sure steering fluid has reached normal operating temperature.Steering wheel axial end play : 0 mm (0 in)
Steering wheel play : 0 – 35 mm (0 – 1.38 in)
Steering wheel turning force
: 7.45 N·m (0.76 kg-m, 66 in-lb)

WHEEL HUB
Revision: 2007 April2007 M35/M45
5. Separate the wheel hub and bearing assembly from drive shaft
by lightly tapping the end with a hammer (suitable tool) and
wood block, and then remove hub lock nut.
CAUTION:
Do not place drive shaft joint at an extreme angle. Also be
careful not to overextend slide joint.
Do not allow drive shaft to hang down without support for
housing (or joint sub-assembly), shaft and other parts.
NOTE:
Use a puller (suitable tool), if the wheel hub and bearing assem-
bly and drive shaft cannot be separated even after performing
the above procedure.
6. Remove the wheel hub and bearing assembly mounting bolts.
7. Remove the wheel hub and bearing assembly.
Axle Housing
1. Refer to the procedure from 1 to 5 in “Wheel Hub and Bearing Assembly”. RAX-5, "REMOVAL" .
2. Remove parking brake shoe and parking brake cable from back plate. Refer to PB-6, "
PARKING BRAKE
SHOE" , Refer to PB-4, "PARKING BRAKE CONTROL" .
3. Remove coil spring. Refer to RSU-16, "
REAR LOWER LINK & COIL SPRING" .
4. Remove mounting bolt and nut in axle side of shock absorber with a power tool.
5. Remove axle side nuts and bolts on radius rod and front lower link with a power tool. Refer to RSU-14,
"RADIUS ROD" , RSU-15, "FRONT LOWER LINK" .
6. Remove cotter pin, then loosen suspension arm mounting nut of axle housing.
7. Remove suspension arm from axle housing so as not to damage ball joint boot using ball joint remover
(suitable tool), and then remove axle housing from the vehicle.
CAUTION:
Temporarily tighten nuts to prevent damage to threads and to prevent ball joint remover (suit-
able tool) from coming off.
Do not place drive shaft joint at an extreme angle. Also be careful not to overextend slide joint.
Do not allow drive shaft to hang down without support for counterpart such as joint sub-assem-
bly, and other parts.
8. Remove the wheel hub and bearing assembly from axle housing.
9. Remove anchor block mounting nuts, and then remove anchor block and back plate from axle housing.
INSPECTION AFTER REMOVAL
Wheel Hub and Bearing Assembly
Check the wheel hub and bearing assembly for wear, cracks, and damage. Replace if there are.
Axle Housing
Check axle housing for wear, cracks, and damage. Replace if there are.
Ball Joint Inspection
Check for boot breakage, axial looseness, and torque of suspension arm ball joint. Refer to RSU-12, "SUS-
PENSION ARM" .
INSTALLATION
Wheel Hub and Bearing Assembly
Installation is the reverse order of removal. For tightening torque refer to RAX-5, "COMPONENT" .
CAUTION:
Do not reuse non-reusable parts.
