What is U0874?

DTC U0874 is a diagnostic trouble code that indicates a communication error between the vehicle's control modules, specifically involving the steering column control module. This code can arise in various vehicles, but it's particularly common in models like the 2015-2018 Chevrolet Silverado and GMC Sierra. When this DTC is triggered, it suggests that the steering column control module is not communicating properly with other modules within the vehicle's network, such as the engine control unit (ECU) or the body control module (BCM). The implications of this error can range from minor inconveniences, like the malfunction of features dependent on the steering column, to more serious safety concerns, such as loss of power steering assist. In many cases, the vehicle may exhibit symptoms like the illumination of the check engine light and the disabling of cruise control functions. The underlying causes can include wiring issues, software glitches, or even component failures. Addressing this code promptly is crucial for maintaining the overall functionality and safety of your vehicle.

System: U - Network (Communication, CAN Bus)

Symptoms

Common symptoms when U0874 is present:

  • Check engine light stays on constantly, indicating a persistent communication issue.
  • Cruise control may be disabled or malfunctioning, leading to inconsistent vehicle speed control.
  • Steering feel may become unresponsive or exhibit erratic behavior, affecting driver control.
  • Loss of other features related to the steering column, such as adjustable steering or integrated controls.
  • Vehicle may enter a 'limp mode' where power steering assist is reduced, compromising safety.

Possible Causes

Most common causes of U0874 (ordered by frequency):

  1. The most common cause is a faulty steering column control module, with a likelihood of about 40%. This can occur due to internal component failure or software issues.
  2. Another frequent cause is damaged wiring or poor connections, accounting for roughly 30% of cases. Corrosion or fraying can disrupt communication between modules.
  3. A third potential cause involves software glitches within the vehicle’s control systems, which can often be resolved through a software update.
  4. A less common but serious cause could be a failure in the CAN bus network, preventing all modules from communicating effectively.
  5. Rarely, issues can arise from aftermarket modifications that interfere with factory wiring or control modules.
