About C0245

C0245 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 C0245 is stored, the module has detected a plausibility fault — the measured value is in the electrical range but is not consistent with expected operating behaviour; and 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 C0245 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) monitors all wheel speed sensor signals and compares them against each other and against calculated vehicle speed to ensure they are within expected operating ranges. DTC C0245 is set when one or more wheel speed signals are detected as implausible, erratic, or outside the allowable range for a calibrated period, despite no hard circuit fault being present. The wheel speed sensors read a toothed tone ring or reluctor on each hub and feed the EBCM a frequency signal proportional to wheel speed. When this code is set, the ABS, traction control, and elec...
