AUTO-CRUISE CONTROL CANCELLATION CHECK
(1) Set the auto-cruise control.
(2) Check to be sure that there is a return to ordinary driving,
and that the illumination of the auto-cruise indicator stops,
when either of the operations below is performed. @ The brake pedal is depressed.
@ The clutch pedal is depressed.
@ TJhEzift lever is moved to the “N” or “P” range.
@I The auto-cruise control main switch is switched OFF.
@ The ignition switch is turned to OFF.
CHECK OF RETURN TO THE SET SPEED BEFORE
CANCELLATION (1) Set the auto-cruise control.
(2) Check to be sure that the auto-cruise control is
cancelled
when either of the operations below is performed.
@ The brake pedal is depressed.
@ The clutch pedal is depressed.
CAST>
(3) Turn the control switch to RESUME position and release
(RESUME switch
ON*OFF) while driving at a vehicle
speed of approximately 40 km/h (25 mph) or higher.
(4) After switching RESUME switch to OFF, check to be sure that there is a return to the auto-cruise control speed before
it will be
cancelled and the vehicle will travel at the constant
speed.
ACCELERATOR CABLES INSPECTION AND
ADJUSTMENT
(I) Turn air conditioning 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 cables.
(6) Check inner cables for correct slack.
(7) If there is too much slack or no slack, adjust play by the following procedures.
0 Remove the actuator’s protector.
0 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.

@ Adjust accelerator cable B (throttle valve side); after
loosening the adjustment bolts at the intake manifold
plenum side and freeing the inner cable, use the adjust-
ment bolts to secure the plate so that the free play of
the inner cable becomes the standard value.
Standard value:
l-2 mm (.04-.08 in.)
NOTE
If 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.
@Confirm that the throttle lever touches the closed throt-
tle position switch.
@ Adjust accelerator cable A (accelerator pedal side) by loosening the lock nut.

@ After making the adjustment of the cable as described above, check to be sure that the throttle lever at the
engine side is caused to move the distance shown in
the illustration when the actuator link is turned.
@ Install the protector to the actuator.
(8) After adjusting, confirm that throttle valve fully opens and closes by operating pedal.

OPERATION l When the engine coolant temperature reaches approximately
85°C (185°F) in the ignition switch
“ON” position, the
therm0 sensor is turned on
to flow electricity through the radiator fan motor relay (coil) and the
therm0 sensor to the ground.
The radiator fan motor relay contact will be
closed.
l Then, electricity will flow through the radiator fan motor and the radiator fan motor relay
(contact) to the ground to rotate the radiator fan
motor.
NOTE
For models equipped with the air conditioning,
refer to GROUP
55-Troubleshooting for in-
formation concerning the operation of the con-
denser fan.

COOLING -Service Adjustment Procedures T210863
SERVICE ADJUSTMENT PROCEDUl$t&
ENGINE COOLANT LEAK CHECK
1. Loosen radiator cap.
2. Confirm that the engine coolant level is up to the filler
neck.
3. Install a radiator cap tester to the radiator filler neck and
apply 160
kPa (23 psi) pressure. Hold pressure for. two
minutes, while checking for leakage from the radiator, hose or connections.
Caution
Be sure to completely clean away any moisture from
the places checked. When the tester is removed, be careful not to spill anyengine coolant from it.
Be careful, when installing and removing the tester
and when testing, not to deform the filler neck of the
radiator.
4.If there is leakage, repair or replace the appropriate part.
RADIATOR CAP PRESSURE TEST
MlOFBAA
1.Use a special tool to attach the cap to the tester.
2.Increase the pressure until the indicator of the gage stops
moving.
Limit: 65
kPa (9.2 psi)
Standard value:
75- 105 kPa (1 1 - 15 psi)
3.Replace the radiator cap if the reading does not remain at
or above the limit.
NOTE
Be sure that the cap is clean before testing, since rust or
other foreign material on the cap seal will cause an im-
proper indication.
