Diagnostic Method
- When the status where there is a large difference between the target exhaust AVCS advance angle amount and the actual exhaust AVCS advance angle amount continues for a constant period of time.
- When the total value of every predetermined time is great after calculating the difference values between the target and actual advanced angle amount during the exhaust AVCS control.
- Abnormality Judgment
Judge as NG when the following conditions are established within the predetermined time.
JUDGMENT VALUE CHART
| Malfunction Criteria | Threshold Value |
|---|---|
| Σ(Target position - Actual position) | > 8000 °CA (bank 1) > 8000 °CA (bank 2) |
| or | |
| Σ(Target position - Actual position) | < -4800 °CA (bank 1) < -4800 °CA (bank 2) |
Time Needed for Diagnosis:
60000 ms
Malfunction Indicator Light Illumination: Illuminates when malfunction occurs in 2 continuous driving cycles.
- Normality Judgment
Judge as OK and clear the NG if the following conditions are established within the predetermined time.
JUDGMENT VALUE CHART
| Malfunction Criteria | Threshold Value |
|---|---|
| Σ(Target position - Actual position) | ≤ 8000 °CA (bank 1) ≤ 8000 °CA (bank 2) and ≥ -4800 °CA (bank 1) ≥ -4800 °CA (bank 2) |
Time Needed for Diagnosis: 60000 ms
