AUTO-CRUISE CONTROL SYSTEM INSPECTION
AUTO-CRUISE CONTROL SWITCH CHECK(1) Turn the ignition key to ON.
(2) Check to be sure that the indicator light within the switch
illuminates when the cruise control switch is switched ON.
(Turn the cruise control switch to the “CRUISE” position.)
AUTO-CRUISE CONTROL SETTING CHECK(1) Switch ON the cruise control switch.
(2) Drive at the desired speed within the range of approxi-
mately 40-145 km/h (25-90 mph).
(3) Press the SET button.
(4) Check to be sure that the speed is the desired constant
speed when the switch is released, and also check to be
sure that the auto cruise indicator light (tithin the combina-tion meter) illuminates.
NOTE1(
If the vehicle speed decreases to approximately 15 km/h
(9 mph) below the set speed, because of climbing a hill for
example, the auto-cruise control will be
cancelled.
SPEED-INCREASE SETTING CHECK
(‘1) Set to the desird speed.
(2) Turn the control switch to RESUME position.
(3) Check to be sure that acceleration continues while the
switch is hold, and that when it is released the constant
speed at the time when it was released becomes the
driving speed.
NOTEEven if, during acceleration, the vehicle speed reaches or
exceeds the high limit [approximately 145 km/h (90
mph)], acceleration will continue, however, when the
switch is released, the set speed (“memorized speed”) will
become the high limit of the vehicle speed.
’ ” ,
SPEED REDUCTION SETTING CHECK(1) Set to the desired speed.
(2) Press the SET button.
(3) Check to be sure that deceleration continues while the
switch is pressed, and that when it is released the
constant speed at the time when it was released becomes
the driving speed.
NOTEIWhen the vehicle speed reaches the low limit [approxi-
mately 40 km/h (25 mph)] during deceleration, the auto-
matic speed control will be
cancelled.

INSPECTION(1) Disconnect the connector.
(2) Check to be sure that there is continuity between
Aconnector terminals 8 and 9 when the shift lever is moved
to the “N” or “P” range.
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
0-0and between
0-0.
Standard value: 50-6OQ
(3) Check that the solenoid valve makes an operating noise
when battery 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 @-@I.
