What vehicles are most commonly affected by C0E0C?

C0E0C is commonly seen in the 2015-2018 Honda Accord, but can also appear in other vehicles with similar BCM configurations. It's essential to keep an eye on these models for electrical issues.

How can I prevent C0E0C from happening again?

To prevent C0E0C, regularly inspect electrical connections and wiring for wear and tear. Additionally, keep your vehicle's software updated and avoid modifications that could affect the electrical system.

What is C0E0C?

DTC C0E0C is a diagnostic trouble code that indicates a problem related to the vehicle's body control module (BCM) or a communication error within the vehicle's network. This code is particularly common in models such as the 2015-2018 Honda Accord, but it can also appear in other makes and models equipped with similar systems. When this code is triggered, it means that the BCM has detected an anomaly that could affect various vehicle functionalities, including lighting, power windows, and locks. The BCM is essential for ensuring that these systems work harmoniously, and a failure could lead to multiple electrical issues. In practical terms, a vehicle displaying this code may experience symptoms like malfunctioning lights, unresponsive power windows, or inability to lock or unlock doors remotely. Ignoring this code can lead to further complications or even complete failure of the affected systems, which could be both inconvenient and costly to repair. Therefore, it's critical for car owners to address the C0E0C code promptly to maintain vehicle safety and functionality.

System: C - Chassis (ABS, Steering, Suspension)

Symptoms

Common symptoms when C0E0C is present:

  • The check engine light may illuminate and stay on, indicating a persistent issue related to the BCM.
  • Drivers might notice that power windows are unresponsive or operate intermittently, which can be frustrating and unsafe.
  • Malfunctioning lighting systems, such as headlights or interior lights, may flicker or fail to operate completely, posing safety risks.
  • Remote keyless entry may stop functioning, making it difficult to lock or unlock doors without using the physical key.
  • Inconsistent warning lights on the dashboard related to various systems may appear, which can confuse and concern the driver.

Possible Causes

Most common causes of C0E0C (ordered by frequency):

  1. The most common cause of the C0E0C code is a failure of the body control module (BCM), with a likelihood of about 40%. This can often stem from water intrusion or electrical shorts.
  2. Another frequent cause is poor electrical connections, which can lead to intermittent communication issues within the vehicle's network. This can be exacerbated by corrosion.
  3. Faulty sensors or wiring harnesses that connect to the BCM can trigger this code. Regular inspections can help prevent this issue by identifying wear or damage early.
  4. Less common but serious causes include damage to the BCM due to voltage spikes, which can happen if the vehicle's battery is improperly charged or if there are aftermarket electrical modifications.
  5. A rare cause might be software glitches within the BCM itself, requiring a software update or reprogramming to resolve.
