The system consists of a control unit, a brake light switch, switches and a speed sensor. The maintenance of this system is carried out in a car service, however, the general nature of the malfunction can be determined independently.
Examination
1. Check fuse.
2. Check the operation of the brake light switch (voltage from the switch deactivates the cruise control system).
3. If the brake lights do not come on or turn off, correct the cause and recheck the cruise control system.
4. Check the freedom of movement of the cruise control cable, replace if necessary.
5. The cruise control speed sensor is mounted in the speedometer. Check the condition of the connectors on the instrument panel.
6. Check the operation of the system on a test drive. In case of abnormal operation of the system, contact a car service.
