Addresses of the output plugs of the on-board control system indicator unit
The block can be in one of five modes.
Off. When the key is not inserted into the ignition switch (lock), the unit is in the "Off" mode.
Standby mode. When the key is inserted into the ignition switch, the unit goes into standby mode and remains in it when the key in the ignition switch is in the "0" ("Off") position. If the driver's door is opened in this mode, the "Forgotten key in the ignition switch" malfunction occurs, the sound signaling device starts to emit an intermittent sound signal for (8±2) s. The signal should turn off when the door is closed, the key is removed from the ignition switch or turned to another position.
Preliminary check of alarms (testing). This mode is activated after turning the key in the ignition switch to the "I" position ("Ignition"). In this case, the sound and all LED alarms should turn on for (4±2) s to check their serviceability. At the same time, faults are monitored by the level sensors and their status is remembered. Until the end of testing, no signaling about the sensor status is performed.

Preliminary control of sensors (sensor status). After testing is completed, there is a pause and the unit switches to the pre-departure parameter control mode (if they exist) is carried out according to the following algorithm:
- lED indicators of those parameters that have gone beyond the norms begin to flash for (8±2) s, after which they remain lit continuously until the key in the ignition switch is turned to position "0" ("Off");
- simultaneously and synchronously with the LED alarms, the sound alarm is switched on, which switches off after (8±2) s.
Monitoring parameters during engine operation. The unit switches to this mode after the preliminary sensor check mode is over. Monitoring of the level sensor parameters is stopped. If a malfunction occurs during movement, the alarm is repeated according to the algorithm given for the "Preliminary sensor check" mode. If during the sound and LED alarm the key in the ignition switch is turned to the "0" position ("Off"), the sound and LED alarm should turn off.
Malfunctions such as "Worn out brake pads" or "Burned out bulb filaments" should remain in memory until the end of the trip - until the key is turned to position "0" ("Off").
If within (8±2) s after the start of the light and sound signaling, one or more more "Malfunction" signals appear, the LED flashing should change to a steady light, and the light indication of newly received signals should turn on according to the described algorithm.
When opening any door of the car, the unit should turn on the interior lighting.
