1. The electric circuit of indication of pressure of motive oil in 4-cylinder engines is presented on an illustration. |
2. Check serviceability of a condition of a combination of devices for what turn a key in the ignition lock in the situation ON (the engine is switched off) and check serviceability of operation of all other control lamps. If control lamps work regularly, pass to the following paragraph, otherwise make necessary recovery repair, or replace a combination of devices.
3. Check the electrical wiring plait socket between a combination of devices and the sensor switch of pressure of oil. For this purpose:
· Turn the ignition key in the situation OFF and disconnect contact from the sensor switch of pressure of motive oil;
· Turn the ignition key in the situation ON and measure tension in a plait between the socket of a combination of devices and "mass" of the chassis (the plug No. 1 of the E11 socket).
If the result of measurement makes more than 10 V, replace the sensor switch of pressure of motive oil, otherwise pass to the following paragraph.
4. Turn a key in the ignition lock in the situation OFF, remove a combination of devices and measure resistance between C14 and C3 plugs. If the result of measurement makes less than 10 Ohms, replace the electrical wiring socket between a combination of devices and the sensor switch of pressure of motive oil. Otherwise repair or replace a combination of devices and a control lamp of pressure of oil.
