Cruise Control: Service and Repair

COMPONENTS





1. Remove the battery negative terminal.
2. Disconnect the cruise control cable and throttle lever connection while turning throttle lever to the full open position.





3. Disconnect the vacuum pump connector and remove the vacuum pump assembly





4. Remove the actuator bracket and disconnect the vacuum hose.
5. Installation is the reverse order of removal.

CRUISE CONTROL MAIN SWITCH





1. Operate the switch. and check for the continuity between the terminals.
2. If continuity is not as specified, replace the switch.

STOP LAMP SWITCH

Stop Lamp Switch:

After operating the stop lamp switch, check for continuity between the terminals.

PIN POSITION SWITCH
1. Disconnect the connector.





2. Check that there is continuity between connector terminals 10 and 11 when the shift lever is moved to the "N" range.

CRUISE VACUUM PUMP

SOLENOID VALVE (CONTROL VALVE, RELEASE VALVE)





1. Remove the auto-cruise vacuum pump connector.
2. Measure the resistance value between connector terminal 1 and 2, and connector terminals 2 and 4.

Standard value: 50 - 60

3. Check that the solenoid valve makes an operating noise when battery voltage is impressed between terminals 2 and 1 and connector terminals 2 and 4.
4. If there is a malfunction of the solenoid valve. Replace the cruise vacuum pump assembly.

MOTOR
1. Remove the cruise vacuum pump connector.
2. Check that the motor revolves when battery voltage applied between connector terminals 2 and 3.

ACTUATOR

Fig. 10 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 as maintained in then inspect and adjust the cruise control cable.
