What is U087E?

The diagnostic trouble code (DTC) U087E indicates a communication error with the steering column control module. This code is often triggered when the vehicle's onboard computer detects that the steering column control module is not responding or is not communicating properly with other modules in the vehicle's network. This can lead to various functional issues, especially related to steering and safety systems. The steering column control module is responsible for various functions, including electronic steering assist and steering wheel controls. When this module fails or loses communication, it can impact the vehicle's handling and driver assistance systems, potentially leading to safety risks. Common scenarios where this code appears include vehicles experiencing issues with power steering, problems with steering wheel controls, or even a malfunctioning airbag system. Understanding this code is crucial, as it may require immediate attention to ensure safe driving conditions. Vehicles commonly affected by this code include models from Chevrolet, GMC, and Buick, particularly from the years 2014 to 2018. If you encounter this code, it’s vital to consult with a qualified technician who can diagnose the issue thoroughly and recommend necessary repairs.

System: U - Network (Communication, CAN Bus)

Symptoms

Common symptoms when U087E is present:

  • The check engine light or service stability system light may illuminate on the dashboard, indicating a potential issue with steering or stability control.
  • Steering may feel heavy or unresponsive, particularly at low speeds, making it difficult to maneuver the vehicle effectively.
  • You might notice that steering wheel controls for audio or cruise control do not function, limiting your ability to operate these systems safely.
  • Error messages related to steering or electronic stability may appear on the dashboard display, alerting you to the underlying issue.
  • In some cases, the vehicle may enter 'limp mode', reducing engine power and limiting vehicle speed to protect the engine and transmission.

Possible Causes

Most common causes of U087E (ordered by frequency):

  1. The most common cause is a failure of the steering column control module, which has a likelihood of around 40%. This module can fail due to manufacturing defects or electrical issues.
  2. Another frequent cause is damaged wiring or poor connections within the steering column area. This can happen from wear and tear or accidental impact, leading to a communication breakdown between modules.
  3. A third cause could be software glitches in the vehicle's control modules. Regular updates and maintaining the vehicle's software can help prevent this issue.
  4. Less common but serious causes include issues with the vehicle’s main computer (ECU), which can cause widespread communication failures across multiple systems.
  5. A rare but possible cause is the presence of aftermarket modifications that interfere with the factory-installed systems, leading to compatibility issues and communication failures.
