INPUT/OUTPUT CHECK MODE

A6E811855430T03

•

The microcomputer built into instrument cluster detects the quality of input signal or individual part.

•

Input/output check mode has both input circuit check and individual part check functions.

•

The operating order of the input/output check mode is the same as that of the current MPV (LW) model.

•

A comparison of available DTCs for the Mazda6 and the current MPV (LW) model is shown below.
