2 drive cycle type

• With the current 323 (BJ) FS engine model, pending codes are deleted when a DTC is stored. With the new Mazda6 (GG, GY), however, even if a DTC is stored, the PCM does not delete the pending code until a normal (malfunction repaired) condition judgement is made.

- The conditions by which the MIL for the second drive cycle type illuminates have been changed as follows.

New Mazda6 (GG, GY)
