ABS/ESC
C2316 Front-RH Valve error (Inlet Valve) - General Information

Component Location





General Description

The HECU is composed of a ECU (Electronic Control Unit ) and an HCU(Hydraulic Control Unit), so the HECU hardware includes all solenoid valves inside the unit as well as the ECU.
Solenoid valves are switched to ON, OFF by HECU when the ABS is activated. Solenoid valves function is to increase, decrease or maintain the hydralic pressure supplied to a wheel cylinder.

DTC Description

The HECU monitors the operation of the valves by checking the drive circuit of the solenid valves, and then sets this code when the unexpcted drive voltage is detected.
For example, the HECU sets the DTC if the electrical feedback signal does not match the actuation signal for the corresconding valve.
