Control system of speed (темпостат) – general information, check of serviceability of functioning of components

Components of system of a tempostat


Tempostat allows to support automatically chosen cruiser speed of the movement of the car. The electric servomotor of a control system of speed is located in a motive compartment and is connected by a cable to the lever of the drive of a butterfly valve. The electronic control unit, switches of management of functioning of a tempostat, the sensor switch of stoplights and the sensor of speed of the movement of the car (VSS) are among the main components of system (address an illustration above). Check of separate functions of system demands use of the special diagnostic equipment, and its performance lies outside qualification of the average amateur mechanic. The description of procedures only of the most general checks allowing to establish the reasons of the most typical refusals of a tempostat is given below.

 PERFORMANCE ORDER

1. Find a safety lock of a tempostat and check its state (see the Section Safety locks - the general information).
2. Ask the assistant to squeeze out several times a pedal of a foot brake – operation of the sensor switch of stoplights reacting to squeezing of a pedal has to lead to shutdown of a tempostat.
3. If stoplights do not react to squeezing of a pedal, find out a cause of failure and repeat check.
4. Visually estimate a condition of the driving cable laid from assembly of the servomotor of a tempostat to draft of a butterfly valve. Replace the damaged or worn-out cable.
5. Monitoring of signals of the sensor of speed of the movement of the car is the basis for functioning of a tempostat. VSS is built in transmission, the description of check of serviceability of its functioning is provided in the Head of the Control system of the engine and decrease in toxicity of the fulfilled gases of the present manual. Estimate a condition of contact connections of a combination of devices (see the Section Removal and installation of a combination of devices).
6. Make trial runs of the car. If it was not succeeded to eliminate violation of functioning of a tempostat during the made corrections, drive away the car on car repair shop for more detailed diagnostics of system with use of the special equipment.
