1. Remove the power transistor connector (I-47)
from the evaporator assembly.
2. Check the conduction between the power
transistor side terminals.
MAX HI Relay
1. Remove the MAX HI relay connector (B-64) from
the blower assembly.
2. Check the conduction between the MAX HI relay
side terminals.In Car Sensor
1. Turn on the ignition switch (the engine is
started). Start the air conditioner in "Full Auto".
2. Make sure that the in car sensor suctions
cigarette smokes and such.
3. Dismount the in car sensor from the automatic
heater/air conditioner control unit. Connect (+)
end and (-) end of the battery to the aspirator
motor side terminals No.1 and No.2
, respectively, then
check if the motor runs normally.I-34

INSPECTION
Before making any adjustments affecting caster, camber
or toe-in, the following front end inspection should be
made.
INSPECT
1. Tires for proper inflation pressure. Refer to “Wheels
and Tires” in section 3E.
2. Front wheel bearings for proper adjustment. Refer to
“Front Wheel Drive” in section 4C.
3. Ball joints, tie rod ends and relay rods. If excessive
looseness is noted, correct before adjusting. Refer to
“Steering Linkage” in section 2A.
4. Wheel and tires for run-out. Refer to “Wheels and
Tires”in section 3E.
5. Trim height. If not within specifications, the
correction must be made before adjusting caster.
6. Steering gear for looseness at the frame.
7. Shock absorbers for leaks or any noticeable noise.
Refer to “Front Suspension” in section 3C.
8. Control arms or stabilizer bar attachment for
looseness. Refer to “Front Suspension“ in section 3C.
9. Alignment equipment. Follow the manufacturer’s
instructions.
10. Level of the vehicle. The vehicle must be on a level
surface.
TRIM HEIGHT ADJUSTMENT
Adjust the trim height by means of the adjusting bolt on
the height control arms.
CAUTION:
When adjusting front end alignment, be sure to begin
with trim height as trim height adjustment may change
other adjusted alignments.
1. Check and adjust the tire inflation pressures.
2. Park the vehicle on a level ground and move the front
of the vehicle up and down several times to settle the
suspension.
3. Make necessary adjustment with the adjusting bolt
on the height control arms.

6. Tighten the lock nut to the specified torque.

4. Similarly adjust the inside wheel angle of the other
side with stopper bolt.

-2°
Outside wheel 32°
NOTE:
Maximum steering angles should be set after adjusting
front wheel alignment.
5. If the stop between the lower link end and the knuckle
comes ahead of the stopper bolt, adjust the stopper
bolt so that inner stopper bolt touches the drop arm
(relay lever).

GENERAL DESCRIPTION
Center track rod assembly
Rod end, outerTrack rodRod end, inner
Relay lever These steps are based on the LHD model.
Outer track rod assembly
Pitman arm
The steering linkage consists of a pitman arm,
relay lever, center track rod and two adjustable
outer track rods.
When the steering wheel is turned, the gear rotates
the pitman arm which forces the center track rod to
one side. The outer track rods, connected to the
center track rod by ball studs, transfer the steering
force to the wheels. The outer track rods are
adjustable and are used for toe-in adjustments.
The center track rod is supported by the pitman
arm and relay lever. The relaylever pivots on a
support attached to the frame.The overall condition of the steering linkage affects
steering performance. If parts are bent, damaged,
worn or poorly lubricated, improper and possibly
dangerous steering action will result.
Whenever any steering linkage components are
repaired or replaced, check the steering geometry
and front end alignment. Refer to Front End
Alignment (Sec. 3A).
