| DTC Strategy |
- Voltage and Current Monitoring
|
- Defective HECU
|
| Threshold Value |
Case1 (Solenoid Valve Open/Short to GND) |
- Valve Feedback Monitoring
- Monitoring Operation Signal and Feedback signal of Solenoid Valve
- Operation signal and feedback signal of solenoid valve does not match
|
| Case 2 (Solenoid Valve Short to Battery) |
- Monitoring solenoid valve electrical fault, pump motor relay and pump motor
- Short is each solenoid valve line by operating each solenoid valve and pump motor one by one
- Monitoring Period: Detects 1 time after Ignition "ON" and vehicle speed of 30 km/h (Approx. 18.6 mph)
|
| Case3 (Solenoid Valve Actuating Monitoring) |
- Short is each solenoid valve line by operating each solenoid valve and pump motor one by one
- Monitoring Period:
- In case of BLS ON: Detects 1 time after Ignition "ON" and vehicle speed of 15 km/h (Approx. 9.3 mph)
- In case of BLS OFF: Detects 1 time after Ignition "ON" and vehicle speed of 6 km/h (Approx. 3.7 mph)
