OBD-II DTC C1246 – ABS Outlet Valve Coil RR Circuit Failure

DTC C1246 meaning

DTC C1246 refers to a fault in the ABS (Anti-lock Braking System) related to the outlet valve coil for the right rear wheel. This code indicates that the ABS control module has detected a malfunction in the electrical circuit that controls the outlet valve coil, which is responsible for regulating brake fluid pressure during ABS operation. A failure in this circuit can lead to improper functioning of the ABS system, affecting vehicle safety and braking performance.

DTC C1246 symptoms

Common symptoms associated with DTC C1246 may include:

  • Illumination of the ABS warning light on the dashboard
  • Inconsistent or unresponsive ABS operation during braking
  • Increased stopping distances, especially on slippery surfaces
  • Potential activation of the brake warning light
