Addresses of the output plugs of the display unit of the on-board monitoring system
The block can be in one of five modes.
Turned off. When the key is not in the switch (lock) ignition, the unit is in the mode «Turned off».
Standby mode. When the key is inserted into the ignition switch, the unit enters standby mode and remains in standby mode when the key in the ignition switch is in the «0» («Turned off»). If the driver's door is opened in this mode, a malfunction occurs «Forgotten key in ignition switch», the buzzer starts beeping intermittently for (8±2) With. The signal should turn off when the door is closed, the key is removed from the ignition switch or turned to another position.
Preliminary control of signaling devices (testing). This mode is activated after turning the key in the ignition switch to the position «I» («Ignition»). At the same time, the sound and all LED signaling devices should turn on for (4±2) to check their correctness. At the same time, faults are monitored by level sensors and their state is stored. Until the end of testing, signaling about the state of the sensors is not carried out.
Preliminary control of sensors (sensor status). After the end of testing, a pause follows and the unit switches to the pre-departure control of parameters. Fault signaling (if they are) carried out according to the following algorithm:
- LED signaling devices of those parameters that have gone beyond the limits begin to flash for (8±2) s, after which they burn constantly until the key is turned in the ignition switch to the position «0» («Turned off»);
- simultaneously and synchronously with the LED signaling devices, the audible signaling device is activated, which is turned off after (8±2) With.
Monitoring parameters during engine operation. The unit switches to this mode after the end of the preliminary control of the sensors. The control of the parameters of the level sensors is terminated. If a malfunction occurs during the movement, the signaling is repeated according to the algorithm given for the mode «Preliminary control of sensors». If, during the sound and LED signaling, the key in the ignition switch is turned to the position «0» («Turned off»), the audible and LED alarms should turn off.
Type faults that have occurred «Brake pad wear» or «Burnt out filaments of lamps» must remain in memory until the end of the trip - until the key is turned to the «0» («Turned off»).
If within (8±2) after the start of the light and sound signaling, one or more signals will appear «Malfunction», then the blinking of the LED 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 car door, the unit must turn on the interior lighting.
