What is U0E68?
The U0E68 diagnostic trouble code (DTC) signifies a communication issue between modules in your vehicle's network. Specifically, this code often indicates that the Body Control Module (BCM) is experiencing trouble communicating with other modules like the Instrument Cluster or the Powertrain Control Module (PCM). This problem can manifest in several ways, such as erratic behavior of electrical components, failure of certain systems, or warning lights illuminating on the dashboard. This communication disruption can occur due to faulty wiring, poor connections, or even software problems in the vehicle's control modules. If you own a 2015-2020 Ford F-150 or similar models, you might notice symptoms like the check engine light illuminating or certain features inoperative, such as power windows or locks. Ignoring this issue can lead to more significant electrical problems, affecting your vehicle's performance and safety. Therefore, it's essential to address the U0E68 code promptly to ensure your vehicle runs smoothly.
System: U - Network (Communication, CAN Bus)
Symptoms
Common symptoms when U0E68 is present:
- The check engine light remains illuminated, causing concern for vehicle health.
- Electrical components like power windows or doors may function erratically, leading to frustration while using the vehicle.
- You may experience a decrease in fuel efficiency due to the vehicle's systems not working in harmony.
- Warning indicators on the dashboard may flicker or not function correctly, impacting your ability to monitor vehicle performance.
- Random resets of the vehicle's electronics, such as radio or navigation systems, may occur frequently.
Possible Causes
Most common causes of U0E68 (ordered by frequency):
- The most common cause is damaged wiring or connectors, with a likelihood of 60%. Corroded or loose connections can disrupt communication between modules.
- A second common cause is software glitches in the BCM or other modules, which can account for about 25% of U0E68 occurrences. Keeping your vehicle's software updated can help prevent this.
- Another cause could be a failing Body Control Module itself, which is less common but might occur in older vehicles. Regular maintenance can help mitigate this risk.
- A less common but serious cause could be water intrusion into electronic components. This can lead to extensive damage, requiring significant repairs.
- In rare cases, electromagnetic interference from aftermarket devices can disrupt module communication, though this is not typical.
