What is C0814?

DTC code C0814 indicates a communication issue with the stability control system in vehicles like the 2013-2018 Chevrolet Silverado and GMC Sierra. Specifically, this trouble code points to a malfunction in the vehicle's stability control module or its connection to the network. This means that the system responsible for keeping your vehicle stable during slippery conditions or sharp turns isn't functioning correctly. When the C0814 code is triggered, the stability control light may illuminate on your dashboard, signaling an issue that needs addressing. In practical terms, this could lead to reduced traction, especially in adverse weather conditions, making your vehicle less safe to drive. Ignoring this code might not just affect your vehicle's performance; it can also lead to more significant issues down the line, such as increased wear on tires or suspension components. Therefore, understanding the implications of code C0814 is crucial for every car owner, particularly those driving affected models. Prompt diagnosis and repair can enhance both safety and vehicle longevity.

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

Symptoms

Common symptoms when C0814 is present:

  • The stability control light on your dashboard remains illuminated, indicating a problem with the stability system.
  • You might notice the vehicle swaying or losing traction more easily on wet or slippery roads, making for an unsettling driving experience.
  • Increased brake sensitivity or unusual braking behavior could occur; for instance, the vehicle may feel like it's braking automatically during normal driving conditions.
  • You may experience reduced performance in the vehicle’s handling, particularly when cornering or during sudden maneuvers.
  • The vehicle may throw additional codes related to the stability control system in conjunction with the C0814 code.

Possible Causes

Most common causes of C0814 (ordered by frequency):

  1. The most common cause is a faulty stability control module, which accounts for about 50% of C0814 occurrences. This module may fail due to age or electrical issues.
  2. Wiring issues, such as damaged or corroded connections, can also trigger the C0814 code and are relatively easy to identify.
  3. An issue with the vehicle's ABS (Anti-lock Braking System) can lead to C0814 being triggered, particularly if the ABS module is malfunctioning.
  4. Less commonly, a software glitch in the vehicle's onboard computer can lead to erroneous readings, causing the code to appear.
  5. In rare cases, a problem with the vehicle's powertrain control module (PCM) could affect the stability control system, though this is less frequent.
