General Information

Component Location





General Description

The HECU supplies battery power to all solenoid valves with a valve relay which is controlled by the Electronic Control UNIT (ECU).
The valve relay and all solenoid valves are installed inside the HECU (Hydraulic and Electronic Control Unit).

DTC Description

ABS ECU monitors voltage of the valve relay to check if ABS ECU can perform ABS control normally.
When the valve relay is switched to ON, the HECU will set this code if the solenoid drive voltage is below permissible voltage ranges for a period of time.
When the valve relay is switched to OFF, the HECU sets this code if the solenoid drive voltage is over the permissible voltage range for a period of time.
