What is U072D?

The U072D diagnostic trouble code (DTC) indicates that there is a communication issue related to the vehicle's body control module (BCM). This code is often triggered when the BCM fails to communicate properly with other control units in the vehicle, such as the engine control module (ECM) or transmission control module (TCM). For example, in a 2015 Honda Civic, this might manifest as erratic behavior of lights, locks, and other electronic features that rely on the BCM. The implications of a U072D code can be significant, as it could lead to various electrical malfunctions, affecting the vehicle's performance and safety. Car owners may notice symptoms such as warning lights on the dashboard, problems with power windows, or issues with the vehicle starting. In the worst-case scenario, failure to address this code can result in compromised vehicle operation. If you're experiencing this code, it's crucial to act promptly to prevent further complications and ensure your vehicle remains reliable and safe.

System: U - Network (Communication, CAN Bus)

Symptoms

Common symptoms when U072D is present:

  • The check engine light remains illuminated, indicating a persistent issue with the vehicle's electronic systems.
  • Drivers may experience power door locks that do not function properly, making it challenging to secure the vehicle.
  • You might notice that power windows intermittently fail to operate, which can be frustrating and inconvenient.
  • Erratic functioning of the vehicle's lights, such as headlights flickering or dashboard lights dimming unexpectedly.
  • The vehicle may have difficulty starting, which can lead to further complications if not addressed promptly.

Possible Causes

Most common causes of U072D (ordered by frequency):

  1. The most common cause of the U072D code is a faulty body control module, which has a 40% likelihood of being the culprit. This module can fail due to age, electrical surges, or water damage.
  2. A second frequent cause is damaged wiring or connectors in the communication circuit, which can occur from wear and tear or environmental exposure, accounting for about 30% of cases.
  3. Another cause might be software glitches in the BCM, which can often be rectified through a software update, representing around 20% of instances.
  4. In rare cases, a malfunctioning engine or transmission control module may also cause the U072D code, necessitating a thorough diagnostic to pinpoint the issue.
  5. Lastly, a less common but serious cause could be short circuits in the vehicle's electrical system, which can lead to significant operational problems.
