What is C0253?

The Diagnostic Trouble Code (DTC) C0253 indicates a fault within the brake control module, specifically regarding the ABS (Anti-lock Brake System) and traction control systems. This code can be triggered by a variety of issues, including electrical faults, sensor malfunctions, or software glitches. When your vehicle's onboard diagnostics detect a problem, it triggers this code, which can lead to warning lights on your dashboard, such as the ABS or traction control light. Notably, this code is commonly found in vehicles such as the 2003-2007 Chevrolet Silverado and 2004-2008 GMC Sierra. If you ignore this code, it could lead to diminished braking performance or even complete failure of the ABS system, which is critical for maintaining control during sudden stops or slippery conditions. Addressing the C0253 code promptly helps ensure that your braking system functions safely and effectively, allowing you to maintain control of your vehicle in adverse conditions. Regular maintenance and prompt diagnostics are key to preventing further complications.

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

Symptoms

Common symptoms when C0253 is present:

  • The ABS warning light illuminates on the dashboard, indicating a potential issue with the braking system.
  • The traction control light may also stay on, reducing traction capabilities during slippery conditions.
  • Drivers may experience a rough or inconsistent brake pedal feel, indicating potential ABS functionality issues.
  • Increased stopping distances may be noticeable, especially in wet or slippery conditions.
  • Intermittent issues with the brake system, such as sudden drops in brake pressure or unusual noises when braking.

Possible Causes

Most common causes of C0253 (ordered by frequency):

  1. Faulty brake control module (60% likelihood) - This is the most common cause of the C0253 code, often resulting from electrical failures or internal component defects within the module.
  2. Wiring issues (20% likelihood) - Damaged or corroded wiring can disrupt the signals to and from the brake control module, leading to this fault code.
  3. Sensor malfunctions (10% likelihood) - A malfunctioning wheel speed sensor can provide incorrect data to the control module, triggering the C0253 code.
  4. Software glitches (5% likelihood) - Occasionally, a software update may be required to reset the control module's functions and clear the fault.
  5. Hydraulic system issues (5% likelihood) - Problems within the hydraulic system can lead to erratic brake performance, which may also trigger this code.
