Cruise Control Servo: Testing and Inspection

Cruise Control Actuator Test




1. Disconnect the 4P connector from the cruise control actuator.
2. Remove the actuator cover.
3. Connect battery power to the No.2 terminal of the 4P connector, and connect ground to the No.1 terminal.
4. Check the magnetic clutch for proper engagement. A clicking sound should be heard and the output linkage should be locked.
5. If the output linkage is not locked, replace the cruise control actuator assembly.
6. With power and ground still connected as in step 3, connect battery power to the No.4 terminal and ground to No.3 terminal, and check that the output linkage starts to turn from full closed position and stops at full opened position by the motor in the actuator.




7. Reverse power and ground at connector terminals, No.4 and No.3, and check that the output linkage reverses and stops at the full closed position.
8. If the output linkage moves sluggishly, or the motor does not operate properly, replace the cruise control actuator assembly.
