What is U00E7?

DTC U00E7 is a generic communication error code that indicates a problem with the vehicle's network communication system. This code often arises when there is a failure in the CAN (Controller Area Network) data transmission between modules in the vehicle. Essentially, it means that one of the control modules in your vehicle is unable to communicate effectively with others. This can lead to multiple issues, including malfunctions in critical systems like the engine, transmission, and even airbag deployment systems. Commonly seen in vehicles like the 2016-2019 Ford Escape and 2017-2020 Chevrolet Malibu, U00E7 can manifest in various ways. For example, you may notice dashboard warning lights flickering or the vehicle's performance degrading. It's essential to address this code promptly, as lingering communication issues can lead to further complications, affecting vehicle safety and performance. Ignoring U00E7 can result in more extensive repairs down the line, which is something every car owner wants to avoid. Understanding this code and its implications can help you take appropriate steps to troubleshoot and resolve the issue effectively.

System: U - Network (Communication, CAN Bus)

Symptoms

Common symptoms when U00E7 is present:

Check engine light stays on constantly, indicating a persistent issue with vehicle communication.
Dashboard warning lights flicker or behave erratically, suggesting communication failures between modules.
Engine hesitates during acceleration, as the control module may not be sending correct signals.
Fuel economy decreased by 10-15%, as the engine may not be operating efficiently due to communication issues.
Loss of functionality in non-critical systems like Bluetooth or navigation, which rely on module communication.

Possible Causes

Most common causes of U00E7 (ordered by frequency):

{'cause': 'Faulty wiring or connectors (50%)', 'details': 'Wiring harnesses or connectors may be damaged due to wear or corrosion, leading to poor communication.'}
{'cause': 'Failed control module (30%)', 'details': "One of the vehicle's control modules may have malfunctioned, preventing it from communicating with others."}
{'cause': 'Software glitches (15%)', 'details': 'Software issues can sometimes cause communication errors; updating the software can resolve this.'}
{'cause': 'CAN bus failure (4%)', 'details': 'Rarely, the CAN bus itself may fail, which can lead to extensive communication problems.'}
{'cause': 'Incompatible aftermarket parts (1%)', 'details': "Installing aftermarket parts that are not compatible with the vehicle's system can trigger U00E7."}
