The system cruise control (if it is established) supports constant speed of the car by means of the electronic control unit (computer) established in salon and a drive, located near the accumulator in an impellent compartment. The drive is connected to the connecting mechanism of a butterfly valve by rope or draft means. Besides a drive, the system turns on the switch of brakes, the coupling switch, operating switches, the relay or connecting wires.

For check of some of functions of this system use of the special equipment and carrying out special diagnostic operations which are inaccessible to the simple motorist is necessary.

Below the description of the general operations on system check cruise control which can help with detection of sources of malfunction is given.


1. Check a safety lock (see subsection 12.1).
2. Ask the assistant to press a brake pedal, and check their work and system work. Turning on of the switch of headlights of a stoplight and if it is established, the switch on a coupling pedal, деактивирует system cruise control.
3. If headlights of a stoplight do not light up or will not go out, eliminate malfunction, and again check system cruise control. Check the switch on a coupling pedal (see subsection 8.2.6).
4. Examine a vacuum hose (if it is established), connected to the servo-driver, and also check the connecting mechanism between the system servo-driver cruise of control and a butterfly valve, and replace if it is necessary.
5. Systems cruise control use many various devices for determination of speed of the car. On these models the sensor of speed is located in a transmission. Turn off a bolt and get the sensor (see subsection 7.2.3), scroll its castor and check sensor signals by means of the digital voltmeter at its rotation. If resistance does not change at sensor rotation, it means is faulty.
6. Pass on the car for system check cruise control. If it does not work, address to experts for further diagnostics and repair.
