6.5. Control lamp of malfunctions (MIL)

The control lamp of MIL lights up in the presence of malfunctions in a control system of the engine. However, the lamp of MIL will not light up after three starts of the engine if the malfunction fixed earlier does not appear any more. After ignition inclusion (before engine start) the control lamp burns constantly that points to normal work of system of diagnostics of malfunctions. The control lamp with OBD-II system lights up at emergence of malfunctions in the following elements of system:

– catalytic converter;
– to fuel system;
– measuring instrument of a consumption of air;
– the sensor of temperature of air arriving in the engine;
– the sensor of temperature of cooling liquid;
– sensor of provision of a butterfly valve;
– oxygen sensor;
– heater of the sensor of oxygen;
– fuel nozzles;
– ignition admissions;
– sensor of an angle of rotation of a cranked shaft;
– sensor of provision of a camshaft;
– to catching system паров fuels;
– sensor of speed of the car;
– valve of adjustment of frequency of rotation of idling;
– electric food;
– ЕСМ;
– violation of functioning of a transmission;
– acceleration sensor;
– inquiry of a signal of MIL.


The control lamp without OBD-II system lights up at emergence of malfunctions in the following elements of system:

- the warmed sensor of oxygen;
- the sensor of absolute pressure in an inlet collector;
- sensor of provision of a butterfly valve;
- the sensor of temperature of cooling liquid;
- modulator of management of frequency of rotation of a cranked shaft of the engine idling;
- fuel nozzles;
- ЕСМ.

Check

PERFORMANCE ORDER
1. After ignition inclusion the control lamp lights up on 5 with then dies away.
2. If the control lamp does not light up, check an electric chain of a lamp, integrity of a safety lock and serviceability of a lamp.

Self-diagnostics

The ESM block constantly supervises entrance and target signals and other signals under certain conditions. At failure detection the ESM block writes down a diagnostic code of malfunction in memory and provides a code exit to the diagnostic socket. It is possible to consider diagnostic codes by means of a control lamp of MIL or the HI-SCAN scanner. Diagnostic codes remain in memory to a detachment of wires from plugs of the storage battery or a socket detachment from the ESM block, and also before their deleting by means of the HI-SCAN scanner.
Prevention

If the socket is disconnected at the included ignition, in memory the code of malfunction of DTC will be written down. In this case disconnect a wire from the negative plug of the storage battery for the period of more than 15 with therefore diagnostic memory will be erased.
