Kia C2324: HECU FaultOVERVIEW
What Does The Kia C2324 Code Mean?
The electrical feedback signal does not match the actuation signal for the corresponding valve for more than 30 ms.
Current controlled valves and under voltage conditions: detection time is 80 ms
A Fault is found if UVR is not within 0.1 battery voltage < valve relay voltage < 0.8 battery voltage.
A Fault is found if valve relay voltage ≥ 0.2battery voltage.
After that all valves are switched on sequential, valve relay voltage and valve feedback is measured.
The valve and pump motor test detects electrical actuation malfunction of ABS valves. The test actuates all valves in series (to detect short cuts or shunts between the valve lines). Faults are detected if there is an error during the test.
The drift test is executed only once during an ignition Cycle. If it detects partly shorted valve coils, almost inoperative coils or malfunction of the valve driver, a failure is recognized.
