Past Failure Indication Mode

WARNING: This page is about a different car, the 2004 Mazda 6. However, it is still accessible from the selected car via links, so may be relevant.

While in present failure indication mode, press the A/C switch to change to the past failure indication mode. In past failure indication mode, past failures (intermittent problems) in the input sensor circuits (open, short circuits) are stored, and the flashing of the rear defroster indicator light on the climate control unit indicates the DTCs.
- If a diagnostic trouble code is indicated, refer to the following diagnostic trouble code table and inspect the appropriate system. (Disconnections and short circuits are stored in the same system even if either occurs only once.)
- If the A/C switch is pressed again while in past failure indication mode, the on-board diagnostic function will return to present failure indication mode.
