General Information

Component Location





General Description

The ABS ECU 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

The ABS ECU monitors voltage of the solenoid valve relay to check if ABS ECU can perform ABS control normally. The HECU monitors the operation of the valves by checking the drive circuit of the solenoid valves, and then sets this code when the unexpected drive voltage is detected.
