Operational CheckEJS001FE
The purpose of the operational check is to confirm that the system operates properly.
CHECKING BLOWER
1. Turn fan switch to 1-speed. Blower should operate on low
speed.
2. Then turn fan switch to 2-speed, and continue checking blower
speed until all speeds are checked.
3. Leave blower on 4-speed.
If NG, go to trouble diagnosis procedure for blower motorMTC-13
.
If OK, continue with next check.
CHECKING DISCHARGE AIR
1. Set the mode control dial to each position.
2. Confirm that discharge air comes out according to the air distri-
bution table.Refer to Discharge Air FlowMTC-5
.
Intake door position is checked in the next step.
If NG, go to trouble diagnosis procedure for mode door motor.
If OK, continue with next check.
CHECKING RECIRCULATION
1. Press REC switch one time. Recirculation indicator should illu-
minate.
2. Listen for intake door position change (you should hear blower
sound change slightly).
If NG, go to trouble diagnosis procedure for intake doorMTC-10
.
If OK, continue with next check.Conditions :Engine running and at
normal operating temper-

On-Vehicle Inspection and ServiceEGS0004E
PLAY INSPECTION
1. Turn steering wheel to straight-ahead position. Start engine and lightly turn steering wheel clockwise and
counter clockwise until front wheels start moving. Measure travel to starting point on circumference of
steering wheel.
2. If play is outside specifications, check following parts for proper installation: steering gear assembly, front
suspension, axles, and steering column
lCheck steering wheel for vertical, horizontal, or axial play.
lLift vehicle and check steering gear mounting bolts and nuts for looseness.
NEUTRAL POSITION INSPECTION
lAfter the wheel alignment inspection, carry out the neutral position inspection. Refer toWT-4.
lBefore removing steering wheel, check steering gear neutral position.
1. Set vehicle to straight-ahead position, and check that steering wheel is in neutral position.
2. If it is not in neutral position, remove steering wheel, and install again in properly.
3. If it is not adjusted within two teeth from center of gear, loosen tie rod lock nut. Then turn it to opposite
direction to adjust until amount of left and right becomes equal.
STEERING TORQUE CHECK
1. Stop vehicle on a dry flat paved road and apply parking brake.
2. Start engine and wait until power steering fluid warms up. Using
a preload gauge, check rotational torque of steering wheel.
3. If torque is outside specifications, check rack sliding torque and
oil pump relief pressure.
STEERING ANGLE INSPECTION
lAfter toe-in inspection, check steering angle. Place front wheels
on turning radius gauges and rear wheels on stands. Level the
vehicle. Check maximum inner and outer wheel steering angles
for LH and RH road wheels.Steering wheel play inspection standard : 0 - 35 mm (0 - 1.38 in)
Steering wheel axial endplay: : 0 mm (0 in)
Tightening torque : 140 - 160 N·m (14.2 - 16.4 kg·m,103-118 ft·lb)
Steering torque : 706 N·cm (72 kg·cm) or less
Rack sliding torque : 153 - 240N (15.5 - 24.5 kg,
34.3-54.2 lb)
Oil pump relief hydraulic
pressure: 8.3 + 0.4 - 0.2 MPa

TROUBLE DIAGNOSIS
NOTE:
1. Light tight-corner braking symptom may occur depending on driving conditions in AUTO mode. This is not
malfunction.
2. Heavy tight-corner braking symptom occurs when vehicle is driven in the following conditions: LOCK
mode, steering wheel is turned fully to either sides, and accelerator pedal was depressed.
3. When the difference of revolution speed between the front and the rear wheels is large, the 4WD mode
does not change to other mode.this is not a malfunction.

4WD solenoid valve
Under the vehicle stopped with engine ON, touch UP, DOWN on
screen. Adjust 4WD solenoid command current.
Check the monitor current at that time. If monitor current is within
approx.±10%, light switch is normal.
CAUTION:
Do not continuously energize solenoid for long period of time.
ECU PART NUMBER
Ignore the ECU part number displayed in the ECU PART NUMBER MODE.
Refer to parts catalog to order the ECU.

3.INSPECTION USING 4WD MODE CHANGE-OVER SWITCH
lOn data monitor screen of the CONSULT-II, check 4WD mode switch.
lCheck if the display changes from ## to 2WD mode when the 2WD switch is pressed.
lCheck if the display changes from ## to AUTO mode when the AUTO switch is pressed.
lCheck if the display changes from ## to LOCK mode when the LOCK switch is pressed.
OK or NG
OK >> No malfunction detected.
NG >>
lNot in AUTO mode. (in 2WD or LOCK mode)
Countermeasure: Slightly depress the accelerator pedal and check that the operation mode
changes to LOCK mode.
lCheck circuit between 4WD mode switch harness connector M39 terminal No.1 (BR) and
4WD control unit harness connector E122 terminal No. 27 (BR).
(AUTO mode is not available because a malfunction is present in the 2WD mode harness.)
NOTICE:
Mechanism of 4WD mode change-over
l2WD mode: Operation changes to 2WD mode when 4WD control unit harness connector E122
terminal No. 27 (BR) is shorted to ground.
lAUTO mode: Operation changes to AUTO mode when 4WD control unit harness connector
E122 terminals No. 27 (BR) and No. 26 (L) is shorted to ground.
lLOCK mode: Operation changes to LOCK mode when 4WD control unit harness connector
E122 terminal No. 26 (L) is shorted to ground.
4WD MODES CANNOT BE SWITCHED AFTER ENGINE IS STARTED
1.INSPECTION USING 4WD MODE CHANGE-OVER SWITCH
lDrive modes cannot be switched after the engine is started.
lOn data monitor screen of the CONSULT-II, check 4WD mode switch.
lCheck if the display changes from ## to 2WD mode when the 2WD switch is pressed.
lCheck if the display changes from ## to AUTO mode when the AUTO switch is pressed.
lCheck if the display changes from ## to LOCK mode when the LOCK switch is pressed.
OK or NG
OK >> No malfunction detected.
NG >>
lCONSULT-II display does not change from ## when the 2WD switch is pressed. Check harness
of the 2WD switch.
lCONSULT-II display does not change from ## when the AUTO switch is pressed. Check har-
ness of the 2WD switch and LOCK switch.
lCONSULT-II display does not change from ## when the LOCK switch is pressed. Check har-
ness of the LOCK switch.
lPerform 4WD mode change-over switch inspection.
WHILE DRIVING, 4WD WARNING LAMP FLASHES RAPIDLY. (WHEN IT FLASHERS FOR
APPROX. ONE MINUTE, THEN DOES NOT ILLUMINATE.)
lWhile driving, 4WD warning lamp flashes rapidly. (when it flashes for approx. one minute, then does not
illuminate.)
Rapid flashing: 2 times/second
This phenomenon protects drivetrain parts when a heavy load is applied to the electronically controlled
coupling and multiple disc clutch temperature increases. It is not a malfunction.
When the difference of diameters by or with the front and rear wheel with AUTO mode the shift switch
occasionally changes to LOCK mode automatically. This is not a malfunction.
When the difference of revolution speed between the front and rear wheel with AUTO mode, the shift
switch occasionally changes to LOCK mode automatically. This is not a malfunction.
