16.30. Description and check of work of a control system by speed (темпостата)

The control system of speed (темпостат or cruise control) supports speed of the car by means of the vacuum servomotor located in an impellent compartment which a cable incorporates to draft of the throttle valve. The system consists of the servomotor, the switch of coupling, the switch of a pedal of a brake, control switches, the relay and vacuum hoses.

In connection with complexity of a control system in the speed should provide its repair the dealer office of service. However the house mechanic can make simple checks of conducting and vacuum connections on existence of small damages which can be easily eliminated. Such checks treat:

• Survey of aktivatorny switches of a control system by speed about damage of wires and weakening of contacts.
• Check of safety locks of system
• The control system of speed works at vacuum therefore it is critical, that all vacuum switches, hoses and connections worked reliably. Check hoses in an impellent compartment on weakening of connections, existence of cracks or obvious leakages of vacuum.
