ABS valve circuit malfunction
Where to start
The ABS valve circuit. As with C0110, power, earth and the unit's connector come first; talk of replacing the hydraulic unit comes after. ⚠️ It is worth knowing that ordinary braking still works with this code: only ABS switches off and the pedal feels as it did. The danger is elsewhere — on a slippery road the car stops saving you from locked wheels, while the ABS lamp stays lit and people stop noticing it. A common cause is not the valve itself but the hydraulic unit's connector: it sits low and collects salt and moisture. Before replacing the unit, unplug the connector, dry it and look for green corrosion.

How the app helps
CarScan reads this code from your car through an OBD-II adapter, shows whether it is active now or only stored, names the module that reported it, and puts it into a plain-text report for your mechanic.
