Detection Condition
WARNING: This page is about a different car, the 2003 Mazda 6. However, it is still accessible from the selected car via links, so may be relevant.
PCM monitors right OCV voltage. If PCM detects right OCV control voltage (calculated from OCV) is less than threshold voltage (calculated from positive battery voltage), PCM determines that right OCV circuit has a malfunction. This is a Continuous Monitor (CM). MIL illuminates if PCM detects malfunction condition during first drive cycle. PENDING CODE is available if PCM detects malfunction condition. FREEZE FRAME DATA is available. DTC is stored in PCM memory.
