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. @ The shift lever is moved to the “N” range.
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.

Caution

@ 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.

AUTO-CRUISE CONTROL VACUUM PUMP INSPECTION

Inspection of solenoid valves (control valve, release valve)
(1) Remove the auto-cruise control vacuum pump connector.
(2) Measure the resistance value between terminals
0-0
and between 0-0.
Standard value: 50-60 Q
(3) Check that the solenoid valve makes an operating noise
when batten/ voltage is impressed between terminals
0-0 and between 0-0.
(4) If there is a malfunction of the solenoid valve, replace the
auto-cruise control vacuum pump assembly.
Motor inspection
(1) Remove the auto-cruise control vacuum pump connector.
(2) Check that the motor revolves when battery voltage is impressed between terminals
@-0.
TSB Revision ACTUATOR INSPECTION

(1) Remove the actuator.
(2) Apply negative pressure to the actuator with the vacuum pump and check that the holder moves more than 35 mm
(1.38 in.). In addition, check that there is no change in the
position of the holder when negative pressure is main-
tained in that condition.
(3) First install the actuator and then inspect and adjust the cruise control cable (Refer to
P.13-394.)
VEHICLE-SPEED SENSOR INSPECTION
