Repair and car operation

Control system of speed (темпостат) - the device and a functioning principle

Models of cars considered in the present Management are equipped by system of additional safety (SRS).

Before to start performance of any works near to the block of a pillow of safety, a steering column or the instrument panel, disconnect SRS in order to avoid reception of traumas at its casual operation (the Section System of additional safety (SRS) - the device and a functioning principle see).

Electroconducting of chain SRS is easy for distinguishing on yellow colour of isolation.

Темпостат allows to support cruiser speed of movement of the car at the level chosen by the driver.

At car movement under a bias or uphill a high-speed mode can change.

The control system темпостата allows to carry out movement in a marching mode (with cruiser speed), to move накатом, to carry out acceleration, to make return to chosen earlier high-speed mode, and also to make step updating of the chosen speed. The vacuum servo-driver (actuation mechanism) of management throttle заслонки is located by position in an impellent compartment of the car. Depression giving on an actuation mechanism is carried out through клапанную assemblage which structure, besides the operating valve, includes also the vacuum pump with приводным the electromotor, and also ventilating and safety valves.

Monitoring of the signals, arriving various information gauges, the relay is put in a functioning basis темпостата and switches which number concern

The gauge-switch of stoplights;
The gauge-switch of disconnection of a chain of a starter (model with РКПП);
The combined switch fixed on a steering wheel темпостата;
The horn relay;
The gauge-switch of the permission of start (model with АТ);
The main switch темпостата on the panel of devices of the car;
The module of management АТ (TCM);
The gauge of speed of car VSS 2.

The self-diagnostics block is included in structure of the module of management темпостата. Reading of codes of the malfunctions brought in memory of the module of self-diagnostics is made by means of the special scanner (24082АА010).

Components of a control system of speed have a following arrangement on the car:

The servo-driver/nasosno-klapannaja assemblage - in an impellent compartment of the car, near to the top support of the right forward rack of a suspension bracket;
The gauge-switch of stoplights - on an arm of a pedal of a foot brake;
The gauge-switch of disconnection of a chain of a starter (model with РКПП) - on an arm of a pedal of coupling;
The management module (ECU) темпостата - under a forward overlay of a threshold of a driver's door;
Diagnostic socket DLC - at the left under the panel of devices;
The gauge-switch of the permission of start (model with АТ) - on a wall картера transmissions;
The gauge of speed (VSS 2) - from above in a back part картера transmissions.
