Tachometer
1. Connect the diagnostic device.
2. Compare the readings of the diagnostic device with the readings of the tachometer.
Fuel flow meter
1. Disconnect the fuel flow sensor connector.
2. Connect a test lamp (3-4 watts 12 V) to contacts 5 and 6, on the connector side.
3. Turn the ignition switch to the "On" position. The lamp should light and the flow meter needle should move.
Fuel level sensor
1. Using a multimeter, measure the resistance at contacts 5 and 6 (A) in each of the extreme positions of the sensor.
2. Check the smoothness of the resistance measurement when moving the float from 0 to "P".
3. If the resistance value is not within the norm, replace the level sensor assembly.
Engine temperature sensor
1. Disconnect the three-pin connector of the temperature sensor in the engine compartment.
2. Turn on the ignition. The temperature indicator should show "Cold". Turn off the ignition.
3. Connect a test lamp (3.4 Watt 12 V) to contact 2 and ground.
4. Turn on the ignition. The indicator light should light and the temperature indicator should show "hot".
5. Check the resistance with an ohmmeter between contacts 2 and ground.
6. Check the sensor resistance according to the table. If the resistance value does not correspond to the norm, replace the sensor.
Oil pressure sensor
1. Check the continuity of the circuit between the sensor contact and the engine housing. The circuit should be closed when the engine is running and open when it is not running.
2. If the conditions are not met, replace the sensor.
Brake fluid level indicator
1. Disconnect the brake fluid level sensor connector.
2. Check the continuity of the circuit between contacts 1 and 2. When pressing the rod, the sensor should close.
Brake fluid level warning light
1. Start the engine.
2. Release the vehicle's parking brake.
3. Disconnect the brake fluid level sensor connector.
4. Connect contacts 1 and 2 of the connector. The warning lamp should light.
Parking brake position switch
The switch is located under the handbrake (A). When you press the switch, its contacts open.
1. Check the continuity of the switch connector circuit. If the parking brake is activated, the circuit is closed; if deactivated, the circuit is open.
