CNSPECTION AN&I ”ADJUSTMENT
For models equipped with the auto-cruise control systemreferto
P.14-136.(1) Turn air conditioner and lights OFF.
Inspect and adjust at no load.
2) Warm engine until stabilized at idle.
3) Confirm idle speed is at prescribed rpm.
4) Stop engine (ignition switch OFF).
5) Confirm there are no sharp bends in accelerator cable.
6) Check inner cable for correct slack.
7) If there is too much slack or no slack, adjust play by the
following procedures.
@ On models with an SOHC engine, turn the ignition
switch to the ON position (without starting the engine)
and leave in that condition for approximately 15
seconds.@
Loosen the adjusting bolts on the air intake plenum, andthen secure the outer cable so that the free play of the
inner cable will be the standard value.
Standard value:
jlr
l-2 mm (.04-.08 in.) \. *
3-5 mm (.12-.20 in.)
NOTEIf there is excessive play of the accelerator cable, the
vehicle speed drop (“undershoot”) when climbing a slope
will be large.
If there is no play (excessive tension) of the accelerator
cable, the idling speed will increase.
(8) After adjusting, confirm that throttle valve fully opens and
closes by operating pedal.
(9) Adjust accelerator cable play and confirm throttle lever
stopper touches the idle switch.
ACCELERATOR SWITCH INSPECTION AND
ADJUSTMENT
NlWlEB(1) After warming up the engine, check to be sure that the
accelerator switch is ON when the accelerator pedal’ is in
the free condition. If there is a malfunction, adjust by using
the adjusting bolt.
(2) Press the accelerator pedal by hand until the accelerator
switch switches from ON to OFF and confirm that the
amount of pedal movement (A in the figure) is within the
standard value range.
Standard value:
Accelerator switch switching point
2-6 mm
(.08-.24 ‘in.)
(3) If the distance (A in the figure) is not within the standard
value, adjust it by using the adjusting bolt.

i-._AUTO-CRUISE CONTROL SYSTEM
- Troubltyshootf$6. CHECKING THE STOP LIGHT SWITCH CIRCUIT
Sub fusible link @
vacuum
w-vStop light
Auto-cruisecontrol unit13A0366Description of operation
When the brake pedal is depressed during constant-speedtravel, the stop light switch’s (NC) contacts for the cruise-control system open, with the result that the current to the
auto-cruise vacuum pump is interrupted, thus canceling the
constant-speed travel.
At the same time, moreover, the closing of the (NO) contacts
for the stop light results in the sending of the cancel signal to
the control unit, so that the auto-cruise vacuum pump current is
discontinued within the control unit, thereby canceling the
constant-speed travel.
The flow of current is from the sub fusible link

’ Measure ball joint starting torque.
Standard value:
0.5-2.5 Nm (4-22 in.lbs.1
3.When starting torque exceeds the standard value, replace tie
rod end.
4.When the starting torque is under the standard value, checkfor play or ratcheting in ball joint. If none of these, it is still
serviceable.
STEERING WHEEL CENTERINGNlSFNAC
SIMPLIFIED STEERING WHEEL CENTERING
Determining Steering Wheel’s Off Center1. For the road test, take along chalk or tape and a ruler.
2. Drive straight ahead on an uncambered level surface.
3.When the vehicle’s wheels are pointing straight ahead, markthe steering wheel hub and column cover with a chalk or
tape line.4. Stop the vehicle and line up the marks on the hub and
column cover.5. Place a tape strip or mark on the steering wheel rim.
6.Hold a ruler next to the rim as shown in the illustration, and
then steer the steering wheel until it is in the desired centered
position.
7.Record the distance the strip or mark on the rim has moved.This is how far the steering wheel is off center. If it is more
than 16 mm
(518 in.) off center, it can be centered by
indexing it ten degrees towards the center.
,Indexing Steering Wheel to Center
ltThe steering wheel shaft has 36 splines, allowing the steering
wheel to be indexed in tendegree increments.
1. Remove the steering wheel.
2. Without disturbing the position of the steering wheel shaft,
re-install the wheel as near on-center as possible.

SERVICE ADJUSTMENT PROCEDURES

STEERING WHEEL FREE PLAY CHECKNlSFABH
1. With engine running (hydraulic operation), set front wheels
straight ahead.2. Measure the play on steering wheel circumference before
wheels start to move when slightly moving steering wheel
in both directions.
Limit: 30 mm (1.2
in.13. When the play exceeds the limit, check for play on steering
shaft connection and steering linkage. Correct or replace.
4.If the free play still exceeds the limit value set steering wheel
straight ahead with engine stopped. Load 5
N (1 lb.1 towardssteering wheel circumference and check play.
Standard value (steering wheel play with engine
stopped): 11 mm
I.43 in.)
If the play exceeds the standard value, remove steering gearbox and check total pinion torque.
STEERING ANGLE CHECKN19FDBJ1. Set front wheels on turning radius gauge and measure
steering angle.Standard values:

2. When not within the standard value, it is probably a toe
problem. Adjust toe (refer to GROUP 2-Service Adjustment
Procedures) and recheck.TIE ROD END BALL JOINT VARIATION CHECK
(SHAFT DIRECTION)N19FVA8The inspection procedure for the tie rod end ball joint variation
is the same as for the manual steering system. (Refer to
P. 19-7.)
TIE ROD END BALL JOINT STARTING TORQUE

STEERING WHEEL CENTERINGNlSFIYAFCenter the steering wheel in the same way as the manual
steering. (Refer to P.19-8.1
STATIONARY STEERING EFFORT CHECKNlSFFAI
1. With the vehicle stopped on a flat, paved surface, turn the
steering wheel to the straight ahead position.
2. Start the engine and set it to 1,000 + 100 rpm.
Caution
After checking the engine rpm., there must be a return to
the standard idling rpm.3. Attach a spring balance to the outer circumference of the
steering wheel and measure the steering force required to
turn the steering wheel from the straight ahead position to
the left and right (within a range of 1.5 turns).
Also check to be sure that there is no significant fluctuationof the required steering force.
Standard value:
Steering effort37
N (8 lbs.) or less
Fluctuation allowance6 N (1.3 Iljs.)‘or less:...
STEERING WHEEL RETURN TO CENTER CHE$$$aETo make this test, conduct a road test and check as follows.
1.Make both gradual and sudden turns and check the steering
“feeling” to be sure that there is no difference in the steeringforce required and the wheel return between left and right
turns.2. At a speed of 35 km/h
(22 mph), turn the steering wheel
90°, and release the steering wheel after 1 or 2 seconds.
If the steering wheel then returns
70” or more, the return
can be judged to the satisfactory.
NOTE
There will be a momentary feeling of “heaviness” when thewheel is turned quickly, but this is not abnormal. (This is
because the oil pump discharge amount is especially apt to
be insufficient during idling.
