How can I diagnose U058E myself using GeekOBD APP?
Using the GeekOBD APP, you can scan for DTCs, view freeze frame data, and monitor live data from your vehicle's modules to pinpoint the issue. Look for discrepancies in module communication and check for any additional codes.
What vehicles are most commonly affected by U058E?
Vehicles most frequently affected include the 2015-2020 Ford Explorer, as well as some Chevrolet and Dodge models. Be sure to check for any recalls or technical service bulletins related to communication issues.
How can I prevent U058E from happening again?
Regular maintenance, including checking wiring and connections, can help prevent U058E. Additionally, keeping your vehicle's software updated and addressing any electrical issues promptly can mitigate future risks.
What is U058E?
The diagnostic trouble code U058E indicates a communication issue between the vehicle's control modules, often involving the Body Control Module (BCM). This code signifies that one module is unable to communicate with another, which can lead to various performance issues. When you see this code, it means that there's a breakdown in the network of the vehicle's electronic systems. For instance, in models like the 2015-2020 Ford Explorer, the issue can stem from faulty wiring, poor connections, or even a malfunctioning module. This breakdown can manifest as erratic behavior of components such as power windows, lighting, and even critical safety features. Drivers may notice that certain features stop working altogether or behave unpredictably. Over time, these communication failures can worsen, leading to more significant problems if not addressed promptly. It's crucial to understand that ignoring a U058E code can lead to not only inconvenience but also potential safety risks, especially if crucial vehicle functions are affected. Regular diagnostics and maintenance can help identify and fix these issues before they escalate.
System: U - Network (Communication, CAN Bus)
Symptoms
Common symptoms when U058E is present:
- The check engine light illuminates and remains on, indicating potential communication problems between modules.
- Power windows may malfunction, either not responding or working intermittently, which can be frustrating for drivers.
- The vehicle's lighting system may behave erratically, with headlights flickering or dashboard lights not functioning as expected.
- Other electronic features, such as the radio or navigation system, may become unresponsive or freeze.
- In some cases, drivers may experience issues with the vehicle starting or stalling unexpectedly, which can be alarming.
Possible Causes
Most common causes of U058E (ordered by frequency):
- Faulty wiring connections are the most common cause, with an approximately 50% likelihood of being the root issue. Poor wiring can lead to intermittent communication failures.
- A malfunctioning Body Control Module (BCM) is the second leading cause, where the module itself fails to send or receive signals correctly, impacting multiple systems.
- Corroded connectors can also contribute significantly to U058E, as corrosion can lead to poor electrical contact. Regular checks of connections can help prevent this.
- Less common but serious is a damaged CAN bus, which is the communication network itself. Damage to this network can result in widespread electrical failures.
- A rare but possible cause could be software issues within the control modules that require a reprogramming update to resolve the communication breakdown.

Diagnostic Steps
Professional U058E Diagnosis Process
Follow these systematic steps to accurately diagnose U058E. Each step builds on the previous one to ensure accurate diagnosis.
Step 1: Step 1: Start with an initial visual inspection of wiring and connectors
Step 1: Start with an initial visual inspection of wiring and connectors. Look for signs of damage, corrosion, or loose connections (5-10 minutes).
Step 2: Step 2: Use the GeekOBD APP to perform an OBD2 scan
Step 2: Use the GeekOBD APP to perform an OBD2 scan. Retrieve all diagnostic codes and freeze frame data for context on the issue (10-15 minutes).
Step 3: Step 3: Conduct component testing with a multimeter to assess suspected faulty modules or wiring (20-30 minutes)
Step 3: Conduct component testing with a multimeter to assess suspected faulty modules or wiring (20-30 minutes).
Step 4: Step 4: After any repairs, perform a system function test to verify that the modules are communicating correctly and clear the codes (10-15 minutes)
Step 4: After any repairs, perform a system function test to verify that the modules are communicating correctly and clear the codes (10-15 minutes).
Step 5: Step 5: Finally, conduct a road test under various conditions to confirm that the vehicle operates without issues and that the U058E code does not reappear (15-20 minutes)
Step 5: Finally, conduct a road test under various conditions to confirm that the vehicle operates without issues and that the U058E code does not reappear (15-20 minutes).
