| DTC Strategy |
Case 1 |
- ECM internal monitoring (knock acquisition check)
|
- Poor connector connection
- Poor power supply
- Faulty ECM
|
| Case 2 |
- ECM internal monitoring (atmospheric pressure sensor-related failure)
|
| Case 3 |
- ECM internal monitoring (internal ATIC communication failure)
|
| Case 4 |
- ECM internal monitoring (EWGA overheating defect)
|
| Enable Condition |
Case 1 |
- Ignition "ON"
- Engine speed more than 32 RPM
|
| Case 2, 3, 4 |
|
| Threshold Value |
Case 1 |
- When abnormality is detected during knock sensor signal suitability judgment (ECU self-diagnosis)
|
| Case 2 |
- When an abnormality is detected during ECU self-diagnosis (hardware circuit, sensor memory check)
|
| Case 3 |
- When ATIC communication error (ECU self-diagnosis) is detected
|
| Case 4 |
- When the temperature of higher than 200°C is measured during diagnosis of ECU power
