This code is frequently seen in 2015-2018 Ford Edge models, as well as other Ford vehicles with similar BCM architectures.
How can I prevent U0E72 from happening again?
Regular vehicle maintenance, including checking wiring and connectors, can help prevent U0E72 from recurring. Additionally, keeping software updated can reduce glitches.
What is U0E72?
DTC U0E72 indicates a communication issue within the vehicle's systems, specifically related to the communication between modules. This code is often present in vehicles like the 2015-2018 Ford Edge, where it signifies that the Body Control Module (BCM) is unable to communicate with other control units in the vehicle. When this code triggers, it can lead to various operational problems, including malfunctioning electrical components like windows, locks, or lights. The implications of U0E72 can range from minor inconveniences to significant safety concerns if essential systems like brakes or traction control are affected. If left unresolved, this issue could escalate, leading to complete failure of the affected systems and requiring costly repairs. Car owners should take this code seriously, as it could indicate deeper underlying problems within the vehicle's electrical architecture. In practical terms, if you notice this code, it’s advisable to seek a professional diagnosis promptly to avoid further complications and ensure the vehicle operates safely and efficiently.
System: U - Network (Communication, CAN Bus)
Symptoms
Common symptoms when U0E72 is present:
- The check engine light stays on constantly, indicating a persistent issue that requires attention.
- Power windows and door locks may fail to operate, making it difficult to enter or exit the vehicle.
- Unexpected electrical system failures, such as dashboard lights flickering or malfunctioning, can be noticed by the driver.
- The vehicle may experience intermittent issues with the anti-lock braking system (ABS), affecting overall safety.
- In some cases, the engine may not start or may stall, indicating a more severe communication problem.
Possible Causes
Most common causes of U0E72 (ordered by frequency):
- The most common cause of U0E72 is damaged wiring or connectors, with a likelihood of 60%. It often results from wear and tear, corrosion, or physical damage.
- Another frequent cause is a faulty Body Control Module itself, which can lead to a complete failure of communication with other modules.
- Poor ground connections can also trigger this code, leading to intermittent electrical issues. Regular maintenance checks can help prevent this.
- Less common but serious causes include issues with the vehicle's power distribution box, which can affect multiple systems at once.
- A rare cause can be software glitches within the BCM, requiring a software update or reprogramming to resolve.
