DTC Strategy |
•
Voltage and Current Monitoring | 1. Defected HECU | |
Threshold Value | Case1 (Solenoid Valve Open/Short to GND) |
•
If the valve relay "ON" and corresponding solenoid driver is "OFF" and below condition lasts for 56 msec. - ABS Valve : Solenoid Valve voltage is less than 2V - ESC(ESP) Valve : Solenoid valve voltage is less than battery voltage * 0.33V(ex. Approx. 4.2V when Battery voltage is 12.6V)
•
If valve relay "ON" and corresponding solenoid driver is "ON" and below condition lasts for 56 msec. - ESC(ESP) Valve(Current Regulated Channel) : Solenoid valve current is less than target current * 90% - ESC(ESP) Valve(Current Non-Regulated Channel) : Solenoid current is less than 300 mA | |
Case 2 (Solenoid Valve Short to Battery ) |
•
If valve relay "ON" and corresponding solenoid driver is "ON" and below condition lasts for 56 msec. - ABS Valve : Solenoid valve is higher than 6A - ESC(ESP) Valve(Current Regulated Channel) : Solenoid Valve current is higher than 2.5A- ESC(ESP) Valve(Current Non-Regulated Channel) : Solenoid Valve current is higher than 5A | ||
