Fail-Safe Table

NOTE: For identification of each cylinder and bank, refer to PRECAUTION FOR IDENTIFICATION OF CYLINDER AND BANK .

When any of the following DTCs is detected, ECM enters fail-safe mode as long as malfunction continues to exist but that mode is canceled when ECM detects normal condition after that.
