Common Questions

What does U0E24 mean and how does it affect my car?

The U0E24 code indicates that your vehicle's body control module is having trouble communicating with other modules. This can lead to various performance issues, including malfunctioning safety systems, erratic electrical behavior, and could potentially leave you stranded if not addressed.

What are the most common causes of U0E24 and how much does it cost to fix?

The most common cause of the U0E24 code is a faulty body control module, which can cost between $300 to $800 to replace. Other causes include damaged wiring or software glitches, which can be less expensive to fix, ranging from $100 to $300.

Can I drive my car with U0E24 or should I stop immediately?

While you may be able to drive your vehicle short distances, it is not advisable. Ignoring the U0E24 code can lead to more significant issues, including complete failure of critical systems. It’s best to have your vehicle diagnosed as soon as possible.

How can I diagnose U0E24 myself using GeekOBD APP?

To diagnose U0E24 using the GeekOBD APP, connect your OBD2 scanner, retrieve the stored codes, and review the freeze frame data. Check the condition of the BCM and related wiring, and look for any additional codes that might provide context for the communication failure.

What vehicles are most commonly affected by U0E24?

The U0E24 code is commonly found in vehicles like the 2015-2020 Ford F-150 and the 2016-2020 Chevrolet Silverado. These models have been noted for BCM-related issues, and regular maintenance or software updates may help prevent future occurrences.

How can I prevent U0E24 from happening again?

To prevent the U0E24 code from reappearing, ensure regular maintenance of your vehicle's electrical systems, including checking for corrosion, making sure connections are secure, and performing software updates as recommended by your manufacturer.

What is U0E24?

The U0E24 diagnostic trouble code indicates a communication issue within the vehicle's network, specifically related to the body control module (BCM). When this code appears, it signifies that the BCM is unable to communicate effectively with other modules, such as the powertrain control module (PCM) or the transmission control module (TCM). This can result in various performance issues and warning lights on your dashboard. It's important to understand that modern vehicles rely heavily on a network of modules to function correctly. When one module fails to communicate, it can lead to erratic behaviors in your vehicle, including electrical system malfunctions, failure of safety features like airbags, and compromised performance of critical systems like the brakes and transmission. If you own a 2015-2020 Ford F-150 or a 2016-2020 Chevrolet Silverado, being aware of this code is crucial as it can impact your vehicle's reliability and safety. The longer you ignore this issue, the more potential damage and repair costs you may incur, which is why it’s essential to address it promptly and seek a thorough diagnostic assessment.

System: U - Network (Communication, CAN Bus)

Symptoms

Common symptoms when U0E24 is present:

  • Check engine light stays on constantly, indicating a problem detected by the vehicle's onboard diagnostics.
  • Dashboard warning lights for various systems illuminate unexpectedly, which could suggest communication issues.
  • Engine performance may be compromised, such as hesitation during acceleration or stalling.
  • Power features like windows or locks may function intermittently or not at all due to the BCM's communication failure.
  • Fuel economy can decrease significantly, with reports of up to a 15% drop due to improper engine management.

Possible Causes

Most common causes of U0E24 (ordered by frequency):

  1. A faulty body control module (BCM) is the most common cause, occurring in about 60% of cases. This component is crucial for the communication between different vehicle systems.
  2. Corroded or damaged wiring harnesses can lead to a communication failure, especially in older vehicles or those exposed to harsh environments.
  3. Software glitches in the BCM or other modules can cause sporadic communication errors. Regular software updates can help prevent these issues.
  4. Less common, but serious, is a failing powertrain control module (PCM) that can disrupt communication with the BCM.
  5. A rare but possible cause is electromagnetic interference (EMI) affecting the vehicle’s electrical systems, often from aftermarket installations.
