About C1247

C1247 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 C1247 is stored, the module has detected an open (broken or disconnected) electrical path in the monitored circuit.

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.

C1247 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 commands each wheel circuit's outlet valve open during ABS or stability control events to release brake pressure at that wheel. DTC C1247 is set when the ABS module's internal driver detects an open circuit on the Right Rear (RR) outlet valve coil, meaning no current is flowing when the coil is energised. The fault is typically electrical, with the module unable to sense expected coil resistance through the RR outlet valve solenoid winding inside the Hydraulic Control Unit (HCU). When this code is active, the ABS warning lamp will illuminate and ABS, Tra...
