Coolant temperature gauge
If the pointer needle is constantly at the beginning of the scale, then with the ignition on, disconnect the wire from the pointer sensor and, through a 20-50 Ohm resistor, connect the wire tip to «weight».
If the arrow deviates, then, therefore, the sensor is faulty, and it must be replaced. If the arrow does not deviate, then remove the combination from the instrument panel, remove the red block and, with the ignition on, connect plug 13 through a 20-50 Ohm resistor (rice. 7-39) white instrument cluster pad with «weight». The deviation of the arrow in this case will indicate the serviceability of the device and the damage to the wire connecting the indicator sensor to the instrument cluster. If the arrow does not deviate, then replace the instrument or the entire instrument cluster.
If the pointer is constantly in the red zone, then with the ignition on, disconnect the wire from the sensor. With a faulty sensor, the arrow should return to the beginning of the scale. If the arrow remains in the red zone, then either the wire has a short circuit with «weight», or the instrument is damaged. The serviceability of the device can be checked by disconnecting the white block from the instrument cluster. With the ignition on, the arrow should be at the beginning of the scale.
Fuel gauge
The verification procedure is similar to that described above.
If the pointer needle is constantly at the beginning of the scale and does not deviate after closing with «weight» tip of the pink wire, the disconnected sender, then you need to check the device. To do this, remove the instrument cluster, disconnect the white block of wires from it and, with the ignition on, through a 20-50 Ohm resistor, connect to «weight» plug 11 of the white connector of the instrument cluster. For a serviceable device, the arrow should deviate.
If the pointer is constantly at the end of the scale, then the device can be checked by disconnecting the white block of wires from the instrument cluster. In this case, for a serviceable device with the ignition on, the arrow should return to the beginning of the scale.
