C2112
ABS / stability-control fault code, listed for 12 vehicle lines from Chrysler, Dodge, Hyundai, Kia. What it means on each one, from published sources, and when the module is the cause.
What C2112 means
Sensor supply 1 voltage circuit high
On: 2005-2020 Chrysler 300 (LX/LD) · 2011-2020 Dodge Durango (WD) · 2008-2020 Dodge Grand Caravan (RT) · 2009-2020 Dodge Journey (JC)
Valve relay error: the solenoid valve relay supply voltage stays out of range after the relay switches on (or does not drop after it switches off)
On: 2011-2015 Hyundai Elantra (MD sedan, JK coupe)
Valve relay error: abnormal voltage in the solenoid-valve relay circuit
On: 2007-2012 Hyundai Santa Fe (CM)
Valve relay error: during its initial check the HECU sees no current on the valve power monitor line (open circuit); causes include wiring or connector, the valve relay, a poor ground or the HECU
On: 2013-2018 Hyundai Santa Fe (DM, 3-row)
Valve relay error: the module monitors the solenoid valve relay voltage and sets this code when the relay supply is not right for normal ABS control
On: 2010-2015 Hyundai Tucson (LM / ix35)
HECU solenoid valve relay voltage fault: open or short in the valve relay supply to the solenoid valves inside the HECU; causes: power supply circuit or HECU
On: 2011-2015 Kia Optima (TF, gasoline) · 2011-2015 Kia Sorento (XM) · 2010-2013 Kia Soul (AM) · 2016-2021 Kia Sportage (QL)
Is it the ABS module?
Check the cheap things first: battery voltage and the main fuses for the ABS pump and module, the ground straps, the module connector (corrosion, a pushed-back pin) and, for wheel-speed codes, the sensor and its wiring at each wheel. If those are good and the code returns as soon as it is cleared — or the scan tool cannot talk to the ABS module at all — the module itself is the likely cause, and that is what we repair.
