What vehicles are most commonly affected by B0E8A?

B0E8A is frequently seen in Chrysler, Dodge, and Jeep models from 2016 onwards. Specific models may include the 2016 Dodge Charger, 2017 Jeep Grand Cherokee, and 2018 Chrysler 300. Always check for any recalls or technical service bulletins related to your specific vehicle.

How can I prevent B0E8A from happening again?

Regular maintenance is key to preventing B0E8A. This includes checking electrical connections, ensuring the BCM is free from water damage, and avoiding aftermarket installations unless done professionally. Regularly using diagnostic tools like the GeekOBD APP can help catch issues early.

What is B0E8A?

The DTC B0E8A is a diagnostic trouble code associated with various Chrysler, Dodge, and Jeep vehicles, particularly models from 2016 onwards. This code indicates a malfunction related to the vehicle's body control module (BCM) and could stem from multiple issues such as faulty wiring, a defective BCM, or problems with the CAN bus communication system. When the BCM detects an irregularity, it triggers this code, which can lead to various symptoms affecting vehicle performance and safety features. Drivers may notice that their dashboard lights behave erratically, or certain electronic features like power windows and door locks may stop functioning. Over time, ignoring the B0E8A code could lead to more severe electronic failures or even complete loss of functionality in affected systems, making it crucial to address the issue promptly. If you own a vehicle from these manufacturers and see this code, it’s not just a nuisance—it could indicate underlying electrical system issues that require immediate attention to avoid further complications. Proper diagnostics and repairs are essential to ensure your vehicle operates safely and reliably.

System: B - Body (Airbags, Lighting, Security, Climate Control)

Symptoms

Common symptoms when B0E8A is present:

  • The check engine light stays on constantly, indicating a serious issue that needs immediate attention.
  • Dashboard lights flicker or behave erratically, which can be distracting and may affect night driving.
  • Power windows and door locks may fail to operate, leading to accessibility issues for passengers.
  • Battery drains faster than normal, possibly due to a malfunctioning BCM that's not managing power correctly.
  • Intermittent failure of electronic components like the radio or climate control system, affecting overall driving comfort.

Possible Causes

Most common causes of B0E8A (ordered by frequency):

  1. Faulty BCM is the most common cause, with a likelihood of 65%. This can happen due to internal failures or software glitches.
  2. Damaged wiring or connections related to the BCM, often caused by corrosion or wear, accounts for about 20% of cases.
  3. Issues with the CAN bus communication system, which is responsible for relaying information between modules, can be a third cause, often preventable with regular inspections.
  4. Less common but serious causes include water ingress into the BCM area, which can lead to electrical shorts.
  5. Rarely, an aftermarket electronic accessory installed improperly can create conflicts within the vehicle's electrical system.
