Chassis Codes: Brakes, Suspension and Steering

C codes for the anti-lock braking system (ABS), stability control, wheel speed sensors, electric power steering and electronically controlled suspension.

When the ABS detects a fault it switches off its own function and stability control, although the normal brakes keep working. These codes directly affect safety and should be fixed soon.

Most searched codes in this system

  • Wheel speed sensors with an erratic signal or an open circuit.
  • ABS hydraulic unit pump or valves.
  • Steering angle sensor not calibrated.
  • Brake module supply voltage.

What to check first

  1. Clean the wheel speed sensor and its magnetic or toothed tone ring: dirt and rust are the most common cause.
  2. Inspect the sensor wiring, which works close to the wheel and is easily damaged.
  3. Calibrate the steering angle sensor after a wheel alignment.
  4. Check the brake fluid level.
