A C0267 diagnostic trouble code indicates an open circuit within the pump motor circuit of a vehicle’s anti-lock braking system (ABS). This typically means the electrical connection to the pump motor is disrupted, preventing the ABS from properly controlling brake pressure during emergency stops or traction loss events. An example of this fault would be the ABS system failing to engage during a skid, indicated by the C0267 code appearing on a diagnostic scan tool.
Addressing an open circuit in the ABS pump motor is critical for maintaining vehicle safety. A properly functioning ABS is vital in preventing wheel lock-up, allowing the driver to retain steering control during braking. Historically, ABS systems were a premium safety feature, but now they are standard equipment on most vehicles due to their proven ability to reduce accidents. The benefits of a functional ABS include shorter stopping distances and increased vehicle stability in challenging road conditions.
