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 target timing advance amount and actual timing advance amount is calculated during AVCS control, and the difference per predetermined time is the specified value or larger.
- Abnormality Judgement
Judge as NG when the following conditions are established within the predetermined time.
Judgement Value
JUDGEMENT VALUE REFERENCE
| Malfunction Criteria | Threshold Value |
|---|---|
| Σ(Target position - Actual position) | > 7000 °CA (Bank 1) > 7000 °CA (Bank 2) |
