Description of AMK 211501

3.1 Computer Design

A general view of the computer’s front panel is shown in Figure 1.

The computer has a housing, on the front part of which is mounted a panel with a liquid crystal display (hereinafter referred to as the display) and ten keys for controlling the computer. On the rear wall of the housing there is a connector for connecting the vehicle harness. Seven keys are used to select the required function group and to select functions within the group, and are designated as follows:

“T”, “KM/H”, “KM”, “L”, “L/100”, “ECU”, “H”.

The “START” key is intended for marking the beginning of a trip and resetting accumulated parameters, for fixing the parameter value in the correction mode, and for enabling or disabling the parameter control mode.

The “+” and “-” keys are used to increase or decrease the parameter value in the parameter correction mode and to view diagnostic information.

The mode switching diagram is given in Appendix V. When the ignition is off, the display shows the current time, and a previously set alarm will sound at the scheduled time.

To cancel the alarm signal, press the “START” key.

Pressing any key other than “-” and “+” turns on the display backlight. The type and combination of pictograms displayed on the screen, as well as the measurement unit symbols, determine the selected function.

The display of the parameters “Current time of day”, “Trip time excluding stops”, and “Total trip time” is accompanied by a flashing dot.

When the alarm is set, the display of the current time is accompanied by a “bell” symbol.

The computer monitors the following parameters:

• maximum vehicle speed;
• on-board network voltage;
• vehicle range based on the remaining fuel in the tank.

Figure 1

When a monitored parameter exceeds its set limit (maximum speed from 20 to 200 km/h depending on the setting, range on remaining fuel less than 50 km, on-board network voltage lower than 10.8 V or higher than 14.8 V), the “bell” symbol starts flashing and an audible signal is generated: for the first two parameters, a signal duration of 3 seconds followed by a 15-second pause is repeated twice.

When the on-board voltage deviates, the audible signal is generated with a 10-second delay, has a duration of 5 seconds followed by a 5-second pause, and is repeated three times. The sound signal is accompanied by a display of the monitored parameter value. The audible signal is reset by pressing the “START” key. After resetting the sound signal, the display of a parameter that has exceeded the set limit will be accompanied by a flashing “bell” symbol. When the parameter returns to its normal value, the alarm indication stops. To enable or disable parameter control mode, in the indication mode of the monitored parameter press the “START” key to set or clear the “bell” symbol.

For example, to set the overspeed monitoring mode, use the “KM/H” key to enter the “Instantaneous speed” mode and press the “START” key to display the “bell” symbol. Enabling or disabling the key press confirmation sound signal is performed in the indication mode of the parameter “Trip time excluding stops” by pressing the “START” key.

The display of the parameters “Average trip speed”, “Average fuel consumption per trip”, and “Range based on remaining fuel” is possible only when the following conditions are met: the parameter “Trip mileage” is greater than 1 km and the parameter “Trip time excluding stops” is greater than 1 min; before meeting these conditions, the symbols “- - - -” are displayed. To reset all accumulated parameters (“Trip time excluding stops”, “Total trip time”, “Total fuel consumption per trip”, “Trip mileage”), press and hold the “START” key for more than 4 seconds in the indication mode of one of these parameters until a two-tone signal sounds.

After resetting, check the status of the mode indicator (presence or absence of the “bell” symbol) in the mode where the reset was performed, as it may have changed its state. If the ETS is absent or there is a malfunction in its circuit, the “Outside temperature” indication mode displays the “Со” symbols.

3.2 Setting Time Parameters

The parameter correction mode is applied to:

• “Current time of day”,
• “Calendar”,
• “Alarm clock” and is activated or exited by the “START” key.

The adjustable digits of the parameter flash. The “+” or “-” keys are used to set the required value. Holding the “+” or “-” keys for more than 0.5 seconds enables auto-repeat mode. To set the clock by time signal, in the “Current time of day” display mode, press and release the “START” key, and on the sixth time signal press the “H” key, which will reset the minutes and seconds digits. When the “Current time of day” parameter matches the set alarm value, three melodic signals are issued, each lasting 30 seconds, with a 1-minute interval. Alarm cancellation is performed as follows: in the “Alarm clock” display mode press and release the “START” key, then press the “H” key. The digital positions will then display blank symbols, and the “bell” symbol will not appear in the “Current time of day” display mode.

3.3 Clock Rate Adjustment

To reduce clock drift, a correction coefficient can be entered. In the “Current time of day” display mode, press and hold the “START” key for 2 seconds – the “C” symbol and a flashing correction coefficient value will appear on the display. Use the “+” or “-” keys to enter the required coefficient value, and press the “START” key to exit the correction mode. The maximum correction coefficient values are ±31. One unit of the correction coefficient corresponds to a change in clock rate of 0.35 seconds per day for positive values and 0.18 seconds per day for negative values.

3.4 Setting Maximum Speed

Enter the maximum speed setting mode by pressing the “START” key in the “Average trip speed” display mode. The display will show the flashing maximum speed value, exceeding which will trigger a warning sound signal. The maximum speed value is changed using the “+” or “-” keys in 5 km/h increments from 20 to 200 km/h. Exit the setting mode by pressing the “START” key.

3.5 Display Backlight Modes

When the instrument lighting is on, the backlight level is adjusted by the vehicle’s instrument scale illumination control. When the instrument lighting is off and the ignition is on, the backlight level is adjusted as follows: in the “Total trip time” display mode press and release the “START” key. All single segments (pictograms) will be displayed, indicating the backlight adjustment mode, and the digital positions will display a number corresponding to the backlight level as a percentage of the maximum value. Use the “+” or “-” keys to set the desired backlight level. Each key press changes the backlight level by 5%. Holding the keys for more than 0.5 seconds enables auto-repeat mode. The set backlight level is retained until the next adjustment. To exit the adjustment mode, press the “START” key.

3.6 Fuel Level Setting

The computer memory contains fuel level sensor (FLS) tables with a resolution of 3 liters (fuel level values at intermediate points are calculated by interpolation). Depending on the type of vehicle and the type of instrument cluster installed, the appropriate fuel level table stored in the computer’s memory must be selected for correct readings. The vehicle may be equipped with electromechanical instrument clusters, which produce an FLS output signal with a maximum voltage of more than 5 V, or electronic instrument clusters, which produce an FLS output signal with a maximum voltage of up to 5 V (electronic clusters are distinguished by the presence of an LCD odometer). The procedure for setting the instrument cluster type and corresponding fuel level table is as follows:

a) disconnect the “Battery” circuit (remove the negative battery terminal or disconnect the vehicle harness connector from the computer);

b) press one of the following keys to select the instrument cluster type: “L” – electromechanical type instrument cluster; “L/100” – electronic type instrument cluster; “KM” – GAZ-3110 vehicle instrument cluster;

c) while holding the selected key, connect the “Battery” circuit (connect the harness connector to the computer) and after 2 seconds release the key.

3.7 Fuel Level Sensor (FLS) Calibration

Due to the large manufacturing tolerance of the vehicle’s FLS parameters, the computer provides a mode for correcting the FLS reading table (calibration) to increase the accuracy of fuel level readings.

WARNING! BEFORE STARTING CALIBRATION, ENSURE THAT THE FLS SIGNAL IS CORRECTLY CONNECTED TO THE COMPUTER AND THAT THE CORRECT TYPE OF INSTRUMENT CLUSTER IS SELECTED.

The calibration procedure can be performed by the vehicle owner if desired.

1. Drain fuel from the tank, leaving the minimum amount necessary for the fuel pump operation (for VAZ vehicles this is 3 liters) – this volume is taken as the zero level.
2. Enter the “Fuel level in the tank” display mode, press and hold the “START” key for 2 seconds; the display will show a flashing digit “0”.
3. Press and hold the “L” key for 1 second until the confirmation sound signal is heard. The display will then show a flashing digit “3”.
4. Add 3 liters of fuel to the tank using a measuring container, wait for the fuel level to stabilize, press and hold the “L” key for 1 second until the confirmation signal sounds. The display will then show a flashing digit “6”.
5. To continue calibration, repeat the above procedure each time adding 3 liters and pressing the “L” key afterwards. Ensure that the total amount of fuel in the tank corresponds to the value displayed for each calibration stage.
6. To complete the calibration mode after recording the last fuel level value, press the “START” key, turn the ignition off and then on again.

Note – The maximum possible fuel level value during calibration is 72 liters.

After engaging reverse gear and turning on the ignition, the display shows “rdy” (short for “ready”) for 1 second, and three short sound signals are emitted. This indicates that the parking device is functioning properly and is ready for operation. If no obstacle is detected, the display shows “--” in the numeric fields. If an obstacle is detected within 40 to 170 cm, the distance is displayed in centimeters. The direction of the obstacle is indicated by symbols located below the numeric fields: “<” – obstacle on the left side of the vehicle; “>” – obstacle on the right side; both symbols indicate an obstacle in the center.

3.9.2 Obstacle Distance Indication is accompanied by audible signals (when the “bell” symbol is set on the display), which increase in frequency as the vehicle approaches the obstacle. For distances from 170 to 90 cm, the frequency is 3 signals/sec; from 90 to 60 cm – 5 signals/sec; from 60 to 40 cm – 8 signals/sec. At distances less than 40 cm, the sound becomes continuous and “StOP” appears on the display. Audible signaling can be enabled (bell symbol flashing at 1 Hz) or disabled (no bell symbol). The bell symbol is set or cleared by pressing and holding the “START” key for more than 2 seconds. When the bell symbol is set, the sound can be temporarily disabled until the end of reverse gear mode by a short press (0.3–1 s) of the “START” key – the bell symbol stops flashing.

3.10 Auxiliary Computer Modes
