What is U0F87?

DTC U0F87 is a diagnostic trouble code that indicates a communication error between the vehicle's control modules, specifically concerning the steering column control module. This error can arise in various models, including the 2016-2021 Chevrolet Malibu and 2017-2020 GMC Acadia. When this code appears, it suggests that the steering column control module is not effectively communicating with other modules in the vehicle, such as the powertrain control module (PCM) or the body control module (BCM). In practical terms, this communication failure can lead to a variety of issues, including the inability to steer properly, malfunctioning driver assistance features, or the dashboard warning lights activating. It is crucial to address this issue promptly, as it could affect your vehicle's handling and safety features. Ignoring this code might lead to more severe problems down the road, including complete failure of steering assist features, which can be dangerous while driving. Regular diagnostics and maintenance can help prevent such issues from arising and ensure the vehicle operates smoothly.

Symptoms

Common symptoms when U0F87 is present:

  • Check engine light stays on constantly, indicating an underlying issue that needs immediate attention.
  • Steering feels loose or unresponsive, making it difficult to control the vehicle effectively.
  • Driver assistance features, such as lane-keeping or adaptive cruise control, may not function properly.
  • Dashboard warning lights may illuminate, alerting the driver to potential malfunctions.
  • Increased difficulty in steering, especially at low speeds, which could pose safety risks.

Possible Causes

Most common causes of U0F87 (ordered by frequency):

  1. The most common cause of U0F87 is a faulty steering column control module, occurring in approximately 60% of cases. This module may fail due to internal faults or exposure to moisture.
  2. A second cause can be damaged wiring or connectors in the steering column area, which can disrupt communication between modules. This may occur over time due to wear or physical damage.
  3. Thirdly, software issues in the vehicle's control modules can lead to communication breakdowns. Regular software updates can help prevent this.
  4. Less common, but more serious, is an electrical short circuit within the steering system. This can be hazardous and requires immediate professional diagnosis.
  5. A rare cause can be a malfunctioning body control module, which can interfere with the entire communication network of the vehicle.
