Diagnosing of malfunctions
 Functions and check of action (check of executive mechanisms)
The given check is carried out on action, after having chosen all functions of the system of automatic thermal control, similar to the table resulted below. At check of self-diagnosing of a circuit it helps to clear distinctly problem items or to check up what was impossible to check up.
Prior to the beginning of start, after simultaneously having pressed AUTO, MODE S/NV, an automatic temperature regulator also translates the switch of ignition in "ON" or after start, the executive mechanism is established in a mode of check and its visual check is carried out.
Display lamps of work are simultaneously lit up and start to blink with the period of 2 seconds 3 times.
The beginning of check of executive mechanisms opens on the basis of 88 STER and every 5 seconds moves to other position (at this time works a buzzer).
If at any stage to press on S/W the fan it stops in this position. And by each new pressing S/W of the fan moves on 1 STER.
As to the fan which is sucking away apertures, a suction aperture, А/С light LED, corresponding to action of everyone STER.
