1. If the same malfunction is found and remains during two cycles of driving, automatically lights up a control lamp of malfunction.
2. A control lamp of malfunction dies away, if during 3 cycles of driving of in a row malfunctions it is not found.
3. The diagnostic code of malfunction (DTC) registers in memory of EBU at failure detection after two cycles of driving in a row. a control lamp of malfunction lights up at failure detection in the second cycle of driving.
At detection of the admission of ignition of a mix the code of malfunction and a control lamp of malfunction registers lights up at once after failure detection.
4. The malfunction code automatically is removed from memory of EBU if the same malfunction is not found during 40 cycles of driving.

The cycle of warming up of the engine corresponds to sufficient time of its work during which the temperature of cooling liquid raised not less than on 4,5 °C from the moment of start of the engine and reaches value not below 70 °C.
The cycle of driving includes start of the engine and car movement after the beginning of regulation of structure of a mix on signals of oxygen sensors.
