What is U0C22?

The diagnostic trouble code (DTC) U0C22 indicates a communication issue within the vehicle's control modules. This code often arises when a module, such as the Body Control Module (BCM) or the Powertrain Control Module (PCM), is unable to communicate properly with other modules in the vehicle's network. In practical terms, this could lead to various electronic failures, including issues with the vehicle's lighting system, power accessories, and other electronic features. For owners of vehicles like the 2016-2021 Ford Explorer, this could manifest as intermittent failures in power windows, door locks, or even the infotainment system. The underlying problem may stem from wiring issues, software glitches, or even faulty connectors. Addressing U0C22 promptly is crucial, as failure to do so may lead to further complications or even safety risks if critical systems are affected. Understanding the specifics of this code is the first step in troubleshooting and resolving the associated issues effectively.

System: U - Network (Communication, CAN Bus)

Symptoms

Common symptoms when U0C22 is present:

  • Check engine light is illuminated or flashing, indicating a potential issue with the vehicle's electronic systems.
  • Power windows may operate intermittently or fail to respond, creating frustration for the driver.
  • Infotainment system may freeze or reset unexpectedly, hindering access to navigation and entertainment features.
  • Unresponsive power door locks, affecting vehicle security and convenience.
  • Erratic behavior of dashboard warning lights, suggesting a deeper electrical problem.

Possible Causes

Most common causes of U0C22 (ordered by frequency):

  1. Faulty wiring or connectors: This is the most common cause of U0C22, with an estimated likelihood of about 40%. Damaged wires or poor connections can disrupt communication between modules.
  2. Software glitches: Occasional software issues within the control modules can prevent proper communication, accounting for approximately 30% of cases.
  3. Corrosion: Corroded connectors or terminals can significantly hinder electrical connections, leading to a 20% chance of triggering this code.
  4. Faulty control modules: In some cases, a defective BCM or PCM could be the root cause, although this is less common and represents about 10% of incidences.
  5. Electrical interference: Rarely, external devices or modifications can cause interference, leading to a communication breakdown.
