4. AWD FUNCTION
If ªtight-corner brakingº occurs when the steering
wheel is fully turned at low speed:
1) Determine the applicable trouble code and
check the corresponding duty solenoid C (transfer)
for improper operation.
2) If the solenoid is operating properly, check
transfer clutch pressure.
3) If oil pressure is normal but ªtight-corner brak-
ingº occurs:
Check the transfer control valve for sticking, and
the transfer clutch facing for wear. [W20B0].> and
7. Stall Test
A: MEASUREMENT
1. GENERAL INFORMATION
The stall test is of extreme importance in diagnos-
ing the condition of the automatic transmission and
the engine. It should be conducted to measure the
engine stall speeds in R and 2 ranges.
Purposes of the stall test:
1) To check the operation of the automatic trans-
mission clutch.
2) To check the operation of the torque converter
clutch.
3) To check engine performance.
2. TEST METHODS
1) Preparations before test:
(1) Check that throttle valve opens fully.
(2) Check that engine oil level is correct.
(3) Check that coolant level is correct.
(4) Check that ATF level is correct.
(5) Check that differential gear oil level is cor-
rect.
(6) Increase ATF temperature to 50 to 80ÉC
(122 to 176ÉF) by idling the engine for approxi-
mately 30 minutes (with select lever set to ªNº
or ªPº).
2) Install an engine tachometer at a location vis-
ible from the driver's compartment and mark the

B: INSPECTION AND ADJUSTMENT
1. WHEEL ARCH HEIGHT (FRONT AND
REAR)
1) Adjust tire pressure to specifications.
2) Set vehicle under ªcurb weightº conditions.
(Empty luggage compartment, install spare tire,jack, service tools, and top up fuel tank.)
3) Set steering wheel in a wheel-forward position.
4) Suspend thread from wheel arch (point ªAº in
figure below) to determine a point directly above
center of spindle.
5) Measure distance between measuring point
and center of spindle.

IInspection
1) Place front wheel on turning radius gauge.
Make sure ground contacting surfaces of front and
rear wheels are set at the same height.
2) Set ST into the center of the wheel, and then
install the wheel alignment gauge.

NOTE:
Refer to the ªSPECIFICATIONS AND SERVICE
DATAº for the caster value.
4. FRONT WHEEL TOE-IN
IInspection
1) Using a toe gauge, measure front wheel toe-in.
Toe-in:
0
±3mm(±0.12 in)
2) Mark rear sides of left and right tires at height
corresponding to center of spindles and measure
distance ªBº between marks.
3) Move vehicle forward so that marks line up with
front sides at height corresponding to center of
spindles.
4) Measure distance ªAº between left and right
marks. Toe-in can then be obtained by the follow-
ing equation:
B þ A = Toe-in
H4M1279
IAdjustment
1) Loosen the left and right side steering tie-rods
lock nuts.
2) Turn the left and right tie rods equal amounts
until the toe-in is at the specification.
Both the left and right tie-rods are right-hand
threaded. To increase toe-in, turn both tie-rods
clockwise equal amounts (as viewed from the
inside of the vehicle).

NOTE:
Thrust angle refers to a mean value of left and right
rear wheel toe angles in relation to vehicle body
center line. Vehicle is driven straight in the thrust
angle direction while swinging in the oblique direc-
tion depending on the degree of the mean thrust
angle.

Here, use only positive toe-in values from each
wheel to substitute foraandbin the equation.
7. STEERING ANGLE
IInspection
1) Place vehicle on a turning radius gauge.
2) While depressing brake pedal, turn steering
wheel fully to the left and right. With steering wheel
held at each fully turned position, measure both the
inner and outer wheel steering angle.
