What vehicles are most commonly affected by C024B?

C024B is often reported in vehicles like the 2015-2018 Chevrolet Silverado and other GM models from that era. Keep an eye on recalls or technical service bulletins related to the braking system.

How can I prevent C024B from happening again?

Regular maintenance, including inspection of wiring and connections, can help prevent C024B. Additionally, keeping the brake system clean and free from corrosion will extend its lifespan.

What is C024B?

The diagnostic trouble code (DTC) C024B indicates an issue with the brake control module's communication with the vehicle's onboard computer system. This code is commonly found in vehicles like the 2015-2018 Chevrolet Silverado. When this code triggers, it typically signifies that the brake control module has detected a fault or malfunction in its operation or communication. This could lead to problems with the vehicle's braking performance, including the anti-lock braking system (ABS) and traction control systems. If left unaddressed, it may lead to compromised vehicle safety, increasing the risk of accidents. Drivers may notice symptoms such as a warning light on the dashboard, changes in braking performance, or the ABS activating unexpectedly. It is important to diagnose this code promptly to avoid potential hazards and ensure the vehicle operates safely. Ignoring the C024B code may lead to more significant issues and costly repairs down the line.

System: C - Chassis (ABS, Steering, Suspension)

Symptoms

Common symptoms when C024B is present:

  • The ABS warning light remains illuminated, indicating a malfunction in the braking system.
  • Drivers may experience unusual brake pedal feel, such as pulsation or firmness that differs from normal operation.
  • There may be a noticeable decrease in fuel efficiency, with reports of up to a 15% drop in some cases.
  • The traction control light may intermittently activate, suggesting issues with the vehicle's stability.
  • In some instances, the driver may notice grinding or unusual noises coming from the brakes during operation.

Possible Causes

Most common causes of C024B (ordered by frequency):

  1. A faulty brake control module is the most common cause, accounting for about 60% of cases. This may result from electrical issues or wear and tear over time.
  2. Wiring issues, such as frayed or damaged connectors, contribute to approximately 25% of failures, leading to poor communication between the brake system and the vehicle's computer.
  3. Corrosion on electrical connections can lead to intermittent faults, representing around 10% of cases. Regular inspections can help prevent this.
  4. Less common causes include software issues within the vehicle's control module, which may require a firmware update to resolve.
  5. Rarely, issues with the hydraulic brake system, such as leaks or component failures, can indirectly trigger the C024B code.
