System of onboard diagnostics

The construction and operation of on-board diagnostics essentially borrowed from the modern model MPV (LW) with the engine GY / FS, except under the conditions described below.

Diagnostic codes, controlled parameters and simulation parameters changed in accordance with the rules.

Introduced the function of self-control KOEO / KOER. Therefore, there is a problem or a successful repair immediately confirmed.

The process of storage pending code is changed as follows.

1 type of driving cycle

The modern model MPV (LW) with the engine GY / FS unfinished codes available. In the model, the Mazda 3 (GG), however, the incomplete code is stored in the PCM during the driving cycle.

Type 2 driving cycle

The modern model MPV (LW) with the engine GY / FS unfinished codes are erased when the recording of diagnostic codes. In the model, the Mazda 3 (GG), even if the diagnosis code is stored, the PCM does not erase incomplete code before the normal state (fault is eliminated).

Mode of operation of a control lamp MIL driving cycle type 2 is amended as follows:

The Mazda 3 (GG)

The PCM determines that the first test cycle there is a fault is detected a diagnostic code, which was recorded in the PCM during the previous driving cycles.

Modern MPV (LW) with the engine GY / FS

The PCM determines that there is a fault in the second test cycle.
