Run a complete scan to retrieve all trouble codes and review the freeze frame data for additional context. Use the app to check the status of the Body Control Module and monitor live data for any anomalies.

What vehicles are most commonly affected by B0AEA?

The B0AEA code is frequently reported in the 2015-2018 Chevrolet Silverado and GMC Sierra models. These vehicles have advanced electrical systems that can be sensitive to faults in the Body Control Module. Keep an eye out for any recalls or Technical Service Bulletins that may address BCM issues.

How can I prevent B0AEA from happening again?

To prevent B0AEA from recurring, ensure regular maintenance of your vehicle's electrical system. Keep connectors clean and free from corrosion, and check for any signs of moisture intrusion. Additionally, keeping your vehicle's software updated can help prevent glitches that might trigger this code.

What is B0AEA?

The DTC code B0AEA indicates a fault related to the Body Control Module (BCM) in your vehicle. This module is integral to managing various electrical systems within the car, including lighting, door locks, and even the anti-theft system. When the BCM detects an issue, it triggers the B0AEA code, which can lead to symptoms like malfunctioning lights or intermittent door lock failures. This code is particularly common in 2015-2018 Chevrolet Silverado and GMC Sierra models, where electronic components are closely integrated. Ignoring this code can lead to more significant electrical problems, potentially affecting the vehicle’s safety and functionality. Typically, the BCM will need to be diagnosed and possibly reprogrammed or replaced. If you’re experiencing issues such as lights flickering or doors locking unexpectedly, it’s vital to address the B0AEA code promptly to avoid further complications down the line.

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

Symptoms

Common symptoms when B0AEA is present:

  • Check engine light stays on constantly, indicating a persistent issue with the BCM.
  • Interior lights flicker or fail to operate correctly, creating a safety concern during night driving.
  • Power windows may operate erratically, leading to frustration and potential security risks.
  • Door locks may malfunction, either failing to lock or unlock, which can compromise vehicle security.
  • Dashboard warning lights may illuminate unexpectedly, signaling issues with various vehicle systems.

Possible Causes

Most common causes of B0AEA (ordered by frequency):

  1. The most common cause of the B0AEA code is a defective Body Control Module, occurring in about 70% of cases. This can happen due to electrical surges or moisture intrusion.
  2. A poor connection in the wiring harness linked to the BCM is the second most frequent cause. Corroded connectors can disrupt communication between the BCM and other systems.
  3. Faulty sensors or switches related to the BCM can also trigger this code. Regular maintenance checks can help prevent these issues by ensuring all components are functioning properly.
  4. Less common but serious causes include short circuits within the BCM itself, which can lead to extensive electrical failures.
  5. A rare cause could be software glitches or outdated firmware in the BCM. Updating the module’s software may resolve these issues.
