2. Press the "AUTO" switch and, without releasing it, press the "OFF" switch on the air conditioning and heating control panel.
3. Determine the malfunction by turning on the temperature indicator sectors.
Note:
- If there are no faults, the temperature indicator will not turn on.
- In case of malfunctions, all sectors of the temperature indicator and sectors indicating malfunctions will light up alternately (at intervals of 1 second).
- The simultaneous presence of faults "A", "C", "E", "G", "I", "L" may indicate a break in the common ground circuit of the sensors (see the table "Faults in the air conditioning system").
4. To complete the test, turn off the ignition.
5. After repairing or replacing faulty components, repeat the test.
