Removal and installation
1. Disconnect a wire from the negative plug of the storage battery.
2. Turn out the screw and remove a frame of a combination of devices.
5. Installation is carried out in the reverse order of removal.
Checking the speedometer
1. Adjust tire pressure.
2. Place the vehicle on a speedometer test stand and chock the rear wheels.
3. Check if the speedometer reading is within the tolerance given in the technical data.
Attention! When checking the speedometer, do not suddenly press the clutch pedal and do not suddenly increase / decrease speed.
Note. Tire wear and inadequate tire pressure lead to increased speed measurement errors.
Tachometer
1. Connect the device «Scan» to the diagnostic socket.
2. Start the engine. Compare the vehicle's speedometer to the test tachometer. If the difference in readings exceeds the allowable values, replace the tachometer.
Warning!
- 1. Reversing the polarity of the tachometer will damage the semiconductors inside the tachometer.
- 2. When removing and installing the tachometer, be careful not to drop or hit it.
Fuel gauge
1. Disconnect the connector from the fuel level sensor.
2. Connect a lamp with a power of 3.4 W and an operating voltage of 12 V to terminals 2 and 3 of the wired part of the connector.
3. Turn on the ignition and make sure that the control lamp burns at full heat and the pointer indicates a full tank.
Resistance test
1. Connect a variable resistance to terminals 2 and 3. Check that the gauge shows the fuel level in accordance with the change in resistance. Otherwise, replace the fuel gauge.
Resistance, Ohm | Level |
110 | E (Empty) |
32,5 | 1/2 |
4,0 | F (Full) |
2. Also make sure that when moving the float out of position «E» into position «F» resistance changes smoothly.
Temperature gauge
1. In the engine compartment, disconnect the connector from the coolant temperature sensor.
2. Turn on the ignition and make sure that the pointer is in the position «cold». Switch off the ignition.
3. Connect a lamp with a power of 3.4 W and an operating voltage of 12 V to the sensor connector terminal and «mass».
4. Turn on the ignition.
5. The control lamp should be on, and the pointer should be in the position «hot».
Temperature sensor
1. Using an ohmmeter, measure the resistance between pins 2 and «weight».
2. If the resistances do not match those given in the table, replace the temperature gauge.
Temperature,°С | 60 | 85 | 110 | 125 |
Resistance, Ohm | 118 | 49 | 25 | 14,6 |
Oil pressure sensor
1. Make sure there is continuity between the sensor contact and the «weight».
2. Make sure that with the engine running there is no continuity between the sensor contact and «weight».
3. Otherwise, replace the oil pressure sensor.
