z
Pull the tape measure up to the steering wheel. Position it
through the steering wheel opening.
z Depress the clutch fully and start the vehicle.
z Shift the transmission into reverse gear, then move the shift
lever forward to the position in between reverse gear and
neutral. Slowly release the clutch pedal (if the vehicle creeps
rearward, move the shift lever forward a little more). The
transmission will behave as if in neutral, but the reverse gear
synchronizer will be bypassed.
z With the clutch pedal up, gently pull the shift lever toward the
reverse gear position. Gear clash can now be heard.
z Slowly depress the clutch pedal. Using the steering wheel
inner seam as a reference, note the measurement when the
gear clash stops or the shift lever slides into reverse gear.
Depress the clutch pedal to the downstop. The difference
between the measurement taken when the gear clash Klj . 12 ba

DIAGNOSIS AND TESTING
Speed Control
Refer to Wiring Diagrams Cell
31 , Speed Control for schematic and connector information.
Principles of Operation
The speed control system is designed to maintain vehicle speed above 48 km/h (30 mph). After the
ON switch is depressed, depressing the SET/ACCEL switch will activate the speed control servo. To
increase a set speed, either depress and hold for continuous acceleration, or momentarily tap the
SET/ACCEL switch for 1.6 km/h (1 mph) acceleration increments. To decrease a set speed, depress
and hold the COAST switch until the target speed is reached, or momentarily tap the COAST switch
for 1.6 km/h (1 mph) deceleration increments. When the speed control system has been disabled by
tapping the brake pedal, the RESUME switch can be depressed and the vehicle will return to the
original set speed if the vehicle is traveling over 48 km/h (30 mph) and the OFF switch has not been
depressed.
NOTE: The deactivator switch is provided as an additional safety feature. Normally, when the brake
pedal is depressed, an electrical signal from the brake lamp circuit to the speed control servo will
deactivate the system. Under increased brake pedal effort, the deactivator switch will open and
remove power to the speed control servo, releasing the throttle independent of the speed control
servo.
NOTE: The air bag sliding contract provides the electrical interface between the steering column wiring
and the speed control actuator switches in the steering wheel.
The inputs to the speed control servo are the:
zvehicle speed signal.
