What vehicles are most commonly affected by C0250?

The C0250 code is frequently seen in 2010-2015 Chevrolet Silverado and GMC Sierra models. Other vehicles from GM during this period may also be affected, so it's essential to stay vigilant for signs of ABS issues.

How can I prevent C0250 from happening again?

Regular maintenance is key to preventing C0250. Ensure that your vehicle's wiring and connectors are in good condition, and perform routine checks on the ABS system as part of your vehicle's maintenance schedule. Additionally, using quality components during repairs can help mitigate future issues.

What is C0250?

The diagnostic trouble code (DTC) C0250 indicates a malfunction within the Anti-lock Braking System (ABS) module. This code is particularly prevalent in vehicles like the 2010-2015 Chevrolet Silverado and GMC Sierra. When the ABS module detects a fault, it triggers the C0250 code, which can lead to a malfunctioning ABS, compromising the vehicle's braking performance. The ABS module is crucial for preventing wheel lock-up during sudden braking situations, allowing the driver to maintain steering control. If left unaddressed, this issue can lead to diminished braking effectiveness and increased wear on brake components. Drivers may notice the ABS warning light illuminated on the dashboard, indicating that the system is not functioning correctly. In severe cases, the vehicle may experience longer stopping distances or unresponsive brakes. Understanding this code is vital for vehicle safety, as ignoring it can lead to hazardous driving conditions. Regular diagnostics and maintenance can mitigate these risks, ensuring that the ABS system operates optimally and providing peace of mind for drivers. If you encounter this code, it’s crucial to address it promptly to maintain your vehicle's safety and performance.

Symptoms

Common symptoms when C0250 is present:

  • The ABS warning light remains illuminated on the dashboard, indicating a fault within the ABS system.
  • Drivers may experience a harsh braking response, where the brakes feel unresponsive or engage erratically during braking.
  • There may be a noticeable decrease in braking efficiency, with longer stopping distances observed when applying the brakes.
  • In some cases, a grinding noise may occur when the brakes are applied, indicating potential internal issues with the ABS module.
  • The vehicle may also exhibit traction control issues, leading to unsafe driving conditions, especially in wet or slippery conditions.

Possible Causes

Most common causes of C0250 (ordered by frequency):

  1. The most common cause of C0250 is a faulty ABS module, with an estimated likelihood of 60%. Often, this may be due to electrical failures or internal component degradation.
  2. A second possible cause is damaged wiring or connectors related to the ABS module, which could lead to intermittent faults in communication between the module and the vehicle's computer.
  3. Another cause could be wheel speed sensor failures, which can mislead the ABS module about wheel rotation, leading to erroneous readings and malfunction.
  4. Less commonly, issues with the vehicle's power supply, such as a weak battery or alternator, can affect ABS performance and trigger the C0250 code.
  5. Rarely, a malfunctioning brake pedal position sensor may also cause this code, affecting the ABS system's ability to function correctly.
