What is U0A96?

The U0A96 diagnostic trouble code indicates a communication issue within the vehicle's network, specifically related to the 'Vehicle Communication Network.' When this code is triggered, it often signifies that the control modules in the vehicle are unable to communicate with each other effectively, which can lead to various operational problems. This code is commonly found in several Ford and Lincoln models manufactured between 2016 and 2021. Real-world implications of this code can include loss of certain functionalities such as infotainment system issues, malfunctions in driver assistance systems, or even problems with engine performance. Car owners may notice symptoms like erratic dashboard lights, unresponsive controls, or in some cases, the vehicle may enter a 'limp mode' to prevent further damage. Addressing a U0A96 code promptly is crucial, as prolonged neglect can lead to more severe electrical issues or system failures. If you encounter this trouble code, it's essential to have a professional diagnostic performed to determine the precise nature of the communication failure and avoid potential safety risks.

System: U - Network (Communication, CAN Bus)

Symptoms

Common symptoms when U0A96 is present:

  • Check engine light stays on constantly, indicating a persistent issue within the vehicle's communication network.
  • Infotainment system may freeze or become unresponsive, causing frustration while driving.
  • Dashboard warning lights may flicker or behave erratically, signaling potential underlying electrical problems.
  • Reduced functionality in driver assistance features like adaptive cruise control or lane-keeping assist.
  • In some cases, the vehicle might enter limp mode, limiting speed and performance to protect the engine.

Possible Causes

Most common causes of U0A96 (ordered by frequency):

  1. The most common cause of U0A96 is a faulty or damaged wiring harness, which has a 50% likelihood of being the issue. This can result from wear and tear or exposure to moisture.
  2. Another frequent cause is a malfunctioning control module, such as the Body Control Module (BCM) or Powertrain Control Module (PCM), which may have issues due to internal faults or software glitches.
  3. Poor connections at the terminals or connectors can also lead to the U0A96 code, often stemming from corrosion or loose connections, which can be prevented with regular maintenance checks.
  4. Less common but serious causes include short circuits in the communication lines, which can lead to extensive damage if not addressed quickly.
  5. A rare cause could be software issues requiring a reprogramming of the vehicle's control modules, typically addressed during routine service.
