2.15.12. Diagnostics of malfunctions of the lubrication system
REASON
|
ELIMINATION METHOD
|
The control lamp does not blink after switching off of ignition
| |
The sensor of pressure of weight of 0,3 bars (brown isolation) is faulty | To include ignition, to disconnect an electrical wiring from the oil pressure sensor and to put to weight. If the control lamp blinks, to replace the sensor |
There is no giving of current to the sensor | To check an electrical wiring and connections |
The control bulb is faulty | To replace control a lamp |
The monitor is faulty | To replace the monitor. The monitor are behind the dashboard |
The control lamp does not die away after start of the engine
| |
Oil is very hotter | If the control lamp dies away after gas supply, all are normal, repair is not required |
The control lamp does not die away after supply of gas or burns during the movement
| |
Too low pressure of oil | To check oil level, if necessary to add; to check oil pressure according to the instruction |
0,3 bars closed an oil pressure sensor electrical wiring on weight | To disconnect a wire from the sensor, to isolate and put aside (not to put to weight), to include ignition. If the control lamp lights up, to check conducting |
The sensor of pressure of oil of 0,3 bars is faulty | To replace the sensor |
The control lamp blinks during the movement, the sound signal is distributed
| |
The sensor of pressure of oil of 1,8 bars (the petrol engine) or 0,9 bars (the diesel engine) is faulty | To check oil pressure, to check the oil pressure sensor. If oil pressure as it should be, and a sound signal is distributed, it is possible to disconnect for a while for continuation of the movement an electrical wiring and to put to weight. If the buzzer continues to work, take out the relay of management from a frame. Without postponing for a long time, to check the sensor of pressure of oil and the control unit, if necessary to replace |
Too low pressure of oil on all turns
| |
It is not enough oil in the engine | To add engine oil |
The reception grid of the pump is polluted | To remove the oil pallet, to clean a reception grid |
The oil pump is worn-out | To remove the oil pump and to check, if necessary to replace |
Radical bearings failed | To remove the engine, to make repair |
Too low pressure of oil on the lowered turns
| |
Gets jammed in open situation the valve of adjustment of pressure as a result of pollution | To remove and check the valve |
Too high pressure of oil at turns is higher than 2000 rpm
| |
The valve of adjustment does not open as a result of pollution | To remove and check the valve |
