If open or short in solenoid value is detected, HECU sets DTC C2380.
Item | Detecting Condition | Possible cause | |
DTC Strategy |
•
Voltage and Current Monitoring | 1. Defected 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 : 1) In case of BLS ON : Detects 1 time after Ignition "ON" and vehicle speed of 15 km/h(Approx. 9.3 mph) 2) In case of BLS OFF : Detects 1 time after Ignition "ON" and vehicle speed of 6 km/h(Approx. 3.7 mph) | ||
Warning Indicator Lamp Status |
•
EBD/ABS/ESC(ESP) Warning Indicator Lamp "ON" | ||
Clear Condition |
•
In case of 1 and 3 - Ignition "OFF" and then "ON"
•
In case of 2 - Ignition "OFF" and then "ON" and Vehicle reference speed over 30 km/h (Approx. 19 mph) | ||
