Speedometer Check Data
Drive shaft speed, min⁻¹ | Speedometer readings, km/h |
500 | 31– 35 |
1000 | 62 – 66,5 |
1500 | 93 – 98 |
2000 | 124 – 130 |
2500 | 155 – 161,5 |
Coolant temperature gauge
The device operates together with the TM-106 sensor. With a sensor resistance of 1000–5000 Ohm, the arrow should be at the beginning of the scale; with a resistance of 98–110 Ohm, it should be at the beginning of the red section (at a pointer temperature of 200°C).
Fuel level indicator
The device is used in conjunction with the BM-150 sensor, which is installed in the fuel tank. This sensor also turns on the fuel reserve indicator light if there are 4–6.5 liters of gasoline left in the tank.
If the sensor resistance is 285–335 Ohm, the arrow should be at the beginning of the scale; if the resistance is 100–135 Ohm, it should be in the middle of the scale; and if the sensor resistance is 7–25 Ohm, it should move to the end of the scale (mark "I").

Speedometer
Speedometer type 17.3802 consists of an arrow indicator of the vehicle speed in km/h and a final counter of the distance traveled by the vehicle in km.
Check the speedometer by comparing its readings with the standard ones. The data for checking is given in the table. Data for checking the speedometer.
Voltmeter
The car is equipped with a voltmeter type 12.3812.
Check the voltmeter by comparing its readings with the control device. The error of the voltmeter readings at the 12 and 14 V marks should not exceed +0.7–0.1 V at a temperature of up to 20±5°C. Before checking, the voltmeter must be kept at a voltage of 12 V for 2 minutes.
