Using the GeekOBD APP, you can perform an OBD2 scan to retrieve codes and freeze frame data, which helps identify when and why the C014D code was triggered. Look for any additional codes that may provide further insight.

What vehicles are most commonly affected by C014D?

Vehicles such as the 2015-2018 Chevrolet Silverado and GMC Sierra are frequently affected by the C014D code due to similar brake system designs and faults. It's advisable to check for any recalls or service bulletins related to your specific model.

How can I prevent C014D from happening again?

Regular maintenance of your vehicle’s brake system, including inspections of wiring and connectors, can help prevent C014D. Additionally, ensuring that software updates are applied can keep the system functioning optimally.

What is C014D?

DTC C014D is a diagnostic trouble code indicating a problem with the vehicle's brake control module. Specifically, this code suggests that the module has detected an issue with the communication between the anti-lock brake system (ABS) and the electronic stability control (ESC) system. This can lead to improper braking performance, including the inability to prevent wheel lock-up during hard braking. For many drivers, this code may appear alongside symptoms such as the ABS warning light illuminating on the dashboard. If left unaddressed, it could not only compromise safety but may also lead to more extensive repairs down the line. Understanding the implications of C014D is crucial, especially for owners of vehicles such as the Chevrolet Silverado from the years 2015 to 2018, which are commonly affected. The vehicle may function normally in some scenarios, but the underlying issues can lead to unpredictable behavior in emergency braking situations. Thus, diagnosing and resolving this code promptly is essential for ensuring the vehicle's reliability and safety on the road.

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

Symptoms

Common symptoms when C014D is present:

  • The ABS warning light remains illuminated on the dashboard, indicating a malfunction.
  • Inconsistent braking performance, especially during hard stops, where the wheels may lock up unexpectedly.
  • A noticeable decrease in vehicle stability during turns or rapid maneuvers, leading to potential skidding.
  • The traction control system may deactivate intermittently, resulting in reduced traction on slippery surfaces.
  • Unusual noises from the braking system, such as grinding or pulsating, indicating possible mechanical issues.

Possible Causes

Most common causes of C014D (ordered by frequency):

  1. The most common cause is a faulty brake control module, which may occur in about 60% of C014D cases. This can happen due to wear and tear or electrical failures.
  2. Wiring issues, such as damaged connectors or frayed wires, can lead to communication failures between the ABS and ESC systems, accounting for approximately 25% of cases.
  3. Corrosion in electrical connectors can prevent proper functioning, so regular maintenance and inspections can help prevent this issue.
  4. A less common cause could be software glitches within the vehicle's onboard computer systems, occurring in about 10% of cases, which may require a software update.
  5. Rarely, a malfunctioning wheel speed sensor can trigger C014D, impacting the vehicle's ability to gauge wheel rotation accurately.
