Diagnostic Method
- When the conditions during which the differences of AVCS target timing advance amount and AVCS actual timing advance amount is large continues for certain amount of time.
- When the differences of AVCS target timing advance amount and AVCS actual timing advance amount is calculated for certain amount of time and the difference is larger than the specified value.
- Abnormality Judgment
Judge as NG when the continuous time of completing the malfunction criteria below becomes 20 seconds or more.
