C1246 — ABS Outlet Valve Coil RR Circuit Failure

System: Chassis  |  Type: Manufacturer-Specific  |  Make: Generic

About C1246

C1246 is a manufacturer-specific chassis diagnostic trouble code. It belongs to the C-prefix family of codes, which covers chassis, braking, steering, suspension, or stability-control faults.

When C1246 is stored, the module has detected an electrical-circuit fault in the wiring, connector, or driver associated with the named component.

Scanning & clearing: Chassis (C) codes are stored in the ABS, traction control, or stability-control modules. An enhanced or OEM-level scan tool is usually required to read and clear them.

C1246 is a manufacturer-specific code. The same code string on a different make may have a different meaning. Always confirm the code's definition against the vehicle's service information for the specific make and model under test.

Code Information

The Anti-lock Brake System (ABS) module controls each wheel circuit's outlet valve by switching the coil through internal high and low side drivers, and continuously monitors the drive line for correct voltage and current behaviour. DTC C1246 is a general circuit failure code, indicating the module has detected the Right Rear (RR) outlet valve coil drive circuit is not behaving as expected. This can be caused by an open winding, a short to ground, a short to battery, an out of range coil resistance, or a fault inside the module driver itself. Because the RR outlet valve coil and its drive wiri...
