Diagnostic Method
- Judge NG when the difference of the amount of AVCS target timing advance and the amount of AVCS actual timing advance becomes large.
- Judge NG when the most retarded learning value is outside of the normal range.
- Abnormality Judgment 1 (P0011, P0021)
Judge as NG when the continuous time of meeting the malfunction criteria below becomes 30 seconds or more.
