Diagnostic Method 2
WARNING: This page is about a different car, the 2013 Subaru Forester. However, it is still accessible from the selected car via links, so may be relevant.
Detect the malfunction by the cumulative value obtained from the amount of variation in λ change.
- Abnormality Judgment
Judge as NG when the following conditions are established.
JUDGMENT VALUE
| Malfunction Criteria | Threshold Value | DTC |
|---|---|---|
| Cumulative value obtained from the amount of variation in λ change Σ |(lambda(n) - lambda(n-1)) - (lambda(n-1) - lambda(n-2))| | < Value from Map | P014C and P014D |
MAP (EXCEPT FOR PZEV MODEL)
| Cumulative value obtained from the amount of variation in λ Σ |lambda(n) - lambda(n-1)| | 0.00 | 4.00 |
| Cumulative value obtained from the amount of variation in λ change | 0.00 | 3.00 |
MAP (PZEV MODEL)
| Cumulative value obtained from the amount of variation in λ Σ |lambda(n) - lambda(n-1)| | 0.00 | 4.50 |
| Cumulative value obtained from the amount of variation in λ change | 0.50 | 2.00 |
Time Needed for Diagnosis: 90 seconds
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.
JUDGMENT VALUE
| Malfunction Criteria | Threshold Value | DTC |
|---|---|---|
| Cumulative value obtained from the amount of variation in λ change Σ |(lambda(n) - lambda(n-1)) - (lambda(n-1) - lambda(n-2))| | ≤ Value from Map | P014C and P014D |
Time Needed for Diagnosis: 90 seconds
