The control panel climate control system


Arrangement of a diagnostic socket of system of the climate control

The automatic system of the climate control provides with regulation of temperature set by the driver irrespective of external temperature of air. The block of management of system receives the information from several gauges to maintain temperature in car salon at demanded level. The gauge of temperature of a cooling liquid is located in a heater casing. The gauge of temperature of arriving air is located outside of the evaporator. The solar gauge is located on the panel of devices from outside the driver. The gauge of temperature of air is located behind a forward lattice, and the management block is located in the panel of devices (fig. the Arrangement of components of system of the climate control see).

The climate control system is equipped by system of self-diagnostics which collects the information on malfunctions and will transform them to codes which register in memory of the computer.

For check of codes of self-diagnostics include ignition, without starting the engine and connect an additional wire separate contact to the designated groove on a diagnostic socket of a central air (fig. the Arrangement of a diagnostic socket of system of the climate control see).

There are 4 categories of self-diagnostics. For a choice of a category of diagnostics use buttons of increase or reduction of the set temperature of system of the climate control.

Category 1. All light-emitting diodes and display segments light up.

Category 2. The malfunction code is highlighted.

Category 3. Check of executive mechanisms is made.

Category 4. Calibration of the gauge of temperature is made.
