About C0277

C0277 is a generic (obd-ii standard) chassis diagnostic trouble code recorded for Holden vehicles. It belongs to the C-prefix family of codes, which covers chassis, braking, steering, suspension, or stability-control faults.

When C0277 is stored, the module has detected a sensor-related fault — the reported value from the named sensor is out of spec.

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.

Because C0277 is a generic OBD-II code, its base definition is shared across manufacturers. The specific diagnostic steps, reference values, and repair procedures can vary by vehicle, and the TaT Diagnostic Assistant includes verified procedures submitted by working technicians.

Code Information

The Electronic Brake Control Module (EBCM) and Powertrain Control Module monitor the brake pedal position sensor signal to determine brake pedal application and travel for brake, stability control, and cruise functions. DTC C0277 is set when an implausible brake pedal position signal, loss of signal, or a circuit fault such as an open circuit, short to ground, or short to battery is detected for a calibrated period. The sensor reports pedal travel as a varying voltage or signal that the modules cross check against the stop lamp switch and other inputs. When this code is set, stability control,...
