2. Checking the automatic transmission control relay.
a) Remove the relay.
b) Connect the voltmeter and power source as shown in the figure.
c) When connecting and disconnecting the power source wire, check the conductivity between terminals "1" and "4" of the connector.
| Power supply | Conductivity |
| Connected | Eat |
| Disconnected | No |
d) Replace the relay if necessary.
3. Checking the electromagnetic valves.
a) Disconnect the solenoid valve block connector.
b) Bring the working fluid temperature to 20°C and measure the resistance at the terminals of the electromagnetic valve block connector (see the table "Checking electromagnetic valves").
c) If the obtained values do not correspond to the technical data, check the power supply and ground circuit and eliminate possible faults.
d) If the above steps do not resolve the problem, check each solenoid valve.
- Remove the solenoid valve block cover.
Block of electromagnetic valves. 1 - electromagnetic valve for controlling the upshift clutch, 2 - electromagnetic valve for controlling the downshift clutch, 3 - electromagnetic valve for controlling the first gear brake and reverse gear, 4 - electromagnetic valve for controlling the second gear brake.
- Measure the resistance at the terminals of the connectors of each solenoid valve.
Nominal resistance (at 20°C) — 2.7 - 3.4 Ohm
- If the measured resistance does not correspond to the nominal value, check the wiring and valve sealing rings, and then repeat the test.
Location of automatic transmission control system components. A - Double switch for refrigerant pressure; B - crankshaft position sensor; C - throttle position sensor with built-in sensor-switch for fully closed throttle position, D - automatic transmission output shaft speed sensor (pulse generator "B"); E - automatic transmission control relay; F - automatic transmission input shaft speed sensor (pulse generator "A"); G - start inhibit switch; H - automatic transmission fluid temperature sensor and automatic transmission control solenoid valves; I - electronic control unit for engine and automatic transmission, J - diagnostic connector.
Table. Checking electromagnetic valves.
| Pin numbers | Valve name | Nominal resistance |
| 6-10 | Solenoid valve for controlling the brake of the first gear and reverse gear | 2.7-3.4 Ohm |
| 4-9 | Second gear brake solenoid valve | 2.7-3.4 Ohm |
| 3-9 | Solenoid valve for controlling the downshift clutch | 27-3.4 Ohm |
| 5-9 | Overdrive clutch control solenoid valve | 2.7 - 3.4 Ohm |
- If the measured resistance still does not match the nominal value, replace the faulty solenoid valve.
Note: Replace the solenoid valve block assembly if necessary.
4. Checking the automatic transmission fluid temperature sensor.
a) Remove the sensor.
b) Using an ohmmeter, measure the resistance between terminals "1" and "2" of the sensor connector at different temperatures of the working fluid.
Table. Nominal values.
| Temperature | Resistance |
| 0°C | 16.70 - 20.50 kOhm |
| 20°C | 7.30 - 8.90 kOhm |
| 40°C | 3.40 - 4.20 kOhm |
| 60°C | 1.90-2.20 kOhm |
| 80°C | 1.00- 1.20 kOhm |
| 100°C | 0.57 - 0.69 kOhm |
Note: When the working fluid heats up to 125°C, the "N" range indicator will start flashing, but when the temperature drops to 115°C, the flashing will stop.
c) If a malfunction of the working fluid temperature sensor is detected, replace the sensor.
Adjusting the automatic transmission control cable and the start inhibit switch
1. Checking the condition of the circuit at the terminals of the engine start prohibition switch connector.
a) Disconnect the engine start inhibit switch connector.
b) Check the condition of the circuit between the connector terminals at different switch positions according to the table provided.
Table. Checking the switch.
2. Check the correspondence of the gears to be engaged for each position of the automatic transmission selector and the correct operation of the gearbox in each range. Adjust if necessary.
3. Set the selector to the "N" position (neutral position).
4. Loosen the adjusting nut securing the automatic transmission control cable to the manual control lever to relieve the tension of the cable.
5. Set the manual control lever to neutral position "N".
6. Loosen the start inhibit switch mounting bolts and turn the switch housing so that the hole in the housing flange aligns with the hole on the manual control lever (section A-A in the figure).
Adjusting the automatic transmission control cable and the start inhibit switch. 1 - bolts, 2 - start inhibit switch lever, 3 - start inhibit switch.
7. Tighten the start inhibit switch mounting bolts.
Note: Do not change the position of the start inhibit switch.

Checking the operation of the automatic transmission selector
1. Raise the parking brake lever.
2. Move the CVT selector from position to each position and check that the selector shifts smoothly and clearly.
3. Check that the engine starts when the selector is in the "P" or "N" position, and that the engine cannot be started when the selector is in other positions.
4. Start the engine, release the parking brake lever and check the operation of the gearbox control mechanism.
When moving the selector from position "N" to "D", "3", "2" or "L" the vehicle should move forward, and when moving the selector to position "R" the vehicle should move in reverse).
5. Turn off the engine.
6. Turn the ignition key to the "ON" position, move the automatic transmission selector from the "P" position to the "R" position and make sure that when the automatic transmission selector is in the "R" position, the reversing lights are on and the buzzer sounds. Note: the ignition switch and selector lock systems do not allow the CVT to be switched to unacceptable operating modes if switching can lead to a breakdown, therefore, to move the selector from the "P" position to other positions, you need to press the brake pedal and turn the key in the ignition switch to any position except "LOCK".
