| DTC Strategy |
|
- Poor connector connection
- Open or short in power supply circuit
- Faulty 12V battery
- Faulty HECU
|
| Enable Condition |
- Normal 12V battery voltage (9 to 16V)
|
| Threshold Value |
Case1 |
- If valve relay voltage does not go up to 80% of supply voltage within 80 ms after valve relay "ON"
- When the voltage difference of drain-source of valve relay FET is more than 1.0 ±0.4V
|
| Case2 |
- If valve relay voltage does not drop to below 80% of supply voltage within 80 ms after valve relay "OFF"
|
