CRUISE CONTROL SWITCH INSPECTION(1) Remove the air bag module using the following procedure.I07FOO12
07NOOl@ Remove the negative terminal of the battery and wait
for more than 30 seconds.

CautionThe capacitor in the SRS diagnosis unit retains
enough voltage to deploy the air bag for a given
period even after disconnection of the battery. If anoperation is performed during that given period,
unintended deployment of the air bag could result
and cause serious injury.@Remove the air bag module. To remove the clock spring
connector
(squib connector) from the air bag module,
force the lock outward and pry it with a plain screwdriv-
er as shown at left so that no undue force will be
exerted on the connector when it is removed.@ The removed air bag module should be stored in a
clean, dry, flat place with the pad side up.
(2) Disconnect the connector of the control switch and operate
the control switch to measure the resistance between the
individual terminals.
If the readings are as shown below, the control switch may
be considered good.

(I) Disconnect the connector.
(2) Check that there is continuity between the terminals when
the clutch pedal is depressed, and that there is no
continuity when the pedal is released.
INHIBITOR SWITCH (“N” POSITION) INSPECTION
(1) Disconnect the connector.
(2) Check to be sure that there is continuity between connec-
tor terminals
@and @when the shift lever is moved to the
“N” range.
VEHICLES SPEED SENSOR INSPECTION
Use circuit tester to check circuit repeats off/on between
terminals when speedometer shaft turned several times.

(1) Remove the vehicle’s speed sensor and connect as shown
in the illustration, using a 3
- 10 kQ resistance.
(2) Use a voltmeter to check for voltage at terminals @ and @
when the pulse generator shaft is turning. (One revolution
is four pulses.)

Inspection of Solenoid Valves (Control and Relief Valves)(1) Disconnect the connector of the vacuum pump assembly.
(2) Measure the resistance values across terminals @ and @
and across terminals @ and
0.Standard value: 50
- 60 R
(3) Check that when the battery voltage is applied across
terminals @ and @ and across terminals @ and
0, the
operating sounds of the solenoid valves are heard.
(4) If the solenoid valves are defective, replace the vacuum
pump assembly.
Inspection of Motor
(1) Disconnect the connector of the vacuum pump assembly.
(2) Check that when the battery voltage is applied across
terminals @ and
@, the motor operates.
ACTUATOR INSPECTION(1) Remove the actuator.
(2) Using a vacuum pump, apply a negative pressure to the
actuator to check that the holder portion moves more than
35 mm (1.4 in.). Retain the negative pressure in that state to
check that the holder portion does not change its position.
(3) After the actuator has been mounted, check and adjust the
cruise control cable. (Refer to
P.13-178.)

SERVICE ADJUSTMENT PROCEDURES
CLUTCH PEDAL INSPECTION AND ADJUSTMENTMZlFAAP
1.Measure the clutch pedal height (from the face of the pedal
pad to the firewall).
Standard value: 177
- 182 mm (6.97 - 7.17 in.)
If the clutch pedal height is not within the standard value
range, adjust as follows:
For vehicles without auto-cruise control system, turn and
adjust the bolt so that the pedal height is the standard
value, and then secure by tightening the lock nut to the
specified torque.
Vehicles with auto-cruise control system, disconnect the
clutch switch connector and turn the switch for standard
clutch pedal height. Tighten the lock nut to the specified
torque.
Specified torque: 13 Nm (9
ft.lbs.)
NOTEWhen the pedal height is lower than the standard value,
loosen the bolt or clutch switch, and then turn the push rod
to make the adjustment. After making the adjustment,
tighten the bolt or clutch switch to reach the pedal stopper,
and then lock with the lock nut.
2. Measure the clutch pedal stroke.
Standard value: 160 mm (6.29 in.) or more
If the clutch pedal stroke deviates from the standard value,
turn the push rod to adjust the stroke.
3. Return the clutch pedal gradually from its full-stroke
position to measure amount of the return made by the
pedal
u,ntil the interlock switch makes an operating sound.
Standard value: 10
- 15 mm (.394 - .591 in.)
If the amount of pedal return deviates from the standard
value, adjust it by loosening the lock nut and turning the
interlock switch.
