What is U0913?

DTC U0913 is a diagnostic trouble code that indicates a communication issue within the automotive network, specifically related to a loss of communication with the vehicle’s Body Control Module (BCM). This code can arise in various makes and models, particularly notable in 2016-2022 Ford Explorers and 2017-2021 Chevrolet Malibus. When the BCM fails to communicate correctly with other modules such as the Transmission Control Module (TCM) or the Engine Control Module (ECM), it can lead to a range of operational problems. Drivers may experience symptoms like warning lights on the dashboard, erratic behavior of electrical systems, or even performance issues like stalling. The loss of communication can stem from wiring issues, module failures, or software glitches, making it crucial to address the U0913 code promptly to avoid further complications. Understanding the implications of this code not only helps in diagnosing the problem but also in preventing potential safety hazards. Ignoring a U0913 code can lead to increased wear on vehicle components and could potentially escalate into more severe issues if left unresolved.

System: U - Network (Communication, CAN Bus)

Symptoms

Common symptoms when U0913 is present:

  • The check engine light remains illuminated, signaling a malfunction that needs attention.
  • Electrical components like power windows or door locks operate erratically, leading to driver frustration.
  • Fuel economy may decrease noticeably, often by 10-15%, as the engine control systems struggle to operate optimally.
  • The vehicle may experience stalling or hesitation during acceleration, causing safety concerns while driving.
  • Dashboard warning lights for various systems may illuminate, indicating multiple faults in the vehicle's network.

Possible Causes

Most common causes of U0913 (ordered by frequency):

  1. The most common cause of U0913 is damaged wiring or connectors related to the BCM, with a likelihood of around 40%. Poor connections can disrupt the signals between modules.
  2. Another prevalent cause is a failure in the Body Control Module itself, which can occur due to manufacturing defects or age, accounting for approximately 30% of cases.
  3. Software glitches or outdated firmware in the vehicle’s control modules can also trigger U0913. Regular software updates at service intervals can help prevent this issue.
  4. Less common but serious causes include electrical shorts or water ingress into the BCM, which can lead to complete module failure.
  5. A rare cause might be a combination of multiple module failures, which can complicate diagnosis and repair efforts.
