C2112 - Valve Relay Error






General Description
The ABS ECU supplies battery power to all solonid valves by way of 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. The monitor function tests the supply voltage of the valves via the Valve feedback lines. If three or more valve response faults occur simultaneously, a fault "supply voltage of valves" is registered.
