Malfunctions and independent diagnostics

The block of management of system of injection Mono-Motronic can distinguish and write down a part of malfunctions which arise during engine operation in memory.

The 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 take advantage of our list of malfunctions in which we have resulted a considerable quantity of possible failures, even such which not to establish own diagnostics.
