| DTC Strategy |
- Monitor voltage, current, temperature
|
- Faulty auxiliary battery
- Fuse open and faulty wire harness
- Faulty IEBU
|
| Enable Condition |
- Normal battery voltage (8 to 16.5V)
- Ignition "ON"
|
| Threshold Value |
Case 1 |
- If valve power is less than (2.0±0.2)V for 60ms when valve relay is on and valve is off
- If any of the following conditions are satisfied for 60ms when valve relay is on and valve power is on
- Valve current is greater than (8.5±2.5)A
- Temperature of the valve driver is greater than 195±20°C (383±68°F)
- If over than 3mA of leakage current of valve circuit is detected for 60ms
|
| Case 2 |
- If valve voltage is less than 76% of Valve Relay Voltage for 60ms when valve is OFF
- If valve voltage is bigger than 30% of Valve Relay Voltage for 60ms when valve power is ON
- If valve control output and valve feedback status is not matched for 60ms
|
| Case 2 |
|
| Warning Lamp |
|
| Disable Condition |
- If valve and valve relay initial active test are normal after ignition off/on
