What are C-codes?

C-codes cover the chassis systems that keep you safe and in control on the road, anti-lock brakes (ABS), electronic stability control (ESC), traction control, power steering, and brake-related sensors. C0xxx codes are standardised across manufacturers; C1xxx–C3xxx codes are manufacturer-specific.

General context

C-codes relate to systems involved in vehicle control and safety, ABS, stability control, braking, and steering. Faults in these systems can affect a vehicle's behaviour in an emergency. Whether continued driving is safe depends entirely on the specific fault, which only a qualified mechanic can determine in person.

We don't assign per-code severity ratings. Whether a specific fault is urgent depends on the cause on a specific vehicle, which only a qualified mechanic can determine.
