Malfunctions and independent diagnostics

The control unit of system of injection of Mono-Motronic can distinguish and write down a part of malfunctions which arise during engine operation in memory. If malfunction did not arise again during the subsequent 10 starts of the engine (sporadic malfunction), it is automatically erased from memory of the control unit. Information on constantly arising failures read out at inspection check in a workshop by means of the special device; in house conditions it is impossible to execute this work. If you suspect malfunction of management of ignition/injection, to decipher indications of the store of malfunctions it is possible only in a workshop. In addition you can use our list of malfunctions in which we gave a large number of possible failures, even such which not to establish own diagnostics. After elimination of malfunctions memory of the store of malfunctions is erased by the reading device.
