What is U0E59?

DTC U0E59 is a diagnostic trouble code that indicates a communication issue within the vehicle's control modules, particularly in Ford F-150 models manufactured between 2015 and 2020. This code signifies that the vehicle's onboard diagnostic system has detected a malfunction in the network communication between modules, which could lead to various operational problems. For instance, if your F-150 is experiencing U0E59, you might notice that certain electronic features are not functioning correctly, like the infotainment system, power windows, or even engine performance issues. The underlying cause of U0E59 usually lies in the wiring, connectors, or the modules themselves. Drivers may encounter symptoms such as warning lights on the dashboard, irregular functionality of electronic components, or even stalling issues. Ignoring this code can lead to more severe complications, including complete failure of critical systems, making it essential to address the issue promptly. If you see the U0E59 code, it is advisable to seek professional assistance or utilize OBD2 diagnostic tools like the GeekOBD APP to pinpoint the exact nature of the problem and start the troubleshooting process.

System: U - Network (Communication, CAN Bus)

Symptoms

Common symptoms when U0E59 is present:

  • Check engine light illuminates and remains on, indicating a fault in the vehicle's systems.
  • Inconsistent performance of electronic features, like window controls and infotainment system, which may intermittently work or fail.
  • Engine may hesitate or stall unexpectedly while driving, leading to safety concerns.
  • Decreased fuel economy, potentially by 10-15%, due to inefficient communication between engine control modules.
  • Increased frequency of electrical gremlins, such as random warning lights or system resets.

Possible Causes

Most common causes of U0E59 (ordered by frequency):

  1. Wiring issues between control modules are the most common cause of U0E59, accounting for about 40% of cases. Poor connections or damaged wires can disrupt communication.
  2. Faulty control module is another significant cause, where the module may fail to send or receive signals properly. This can happen due to manufacturing defects or wear and tear.
  3. Corrosion in connectors can lead to communication problems. Regular maintenance and inspections can help prevent this issue. Look for signs of rust or moisture.
  4. Less common but serious causes include software glitches or updates needed for the vehicle’s system, which might require a visit to the dealership.
  5. Rarely, a complete failure of the vehicle’s electrical system can cause U0E59, often resulting from severe electrical damage or fire.
