What is C06FC?

The Diagnostic Trouble Code (DTC) C06FC typically indicates an issue with the vehicle's communication network, specifically related to the body control module (BCM) or other related components. This code is often triggered when the BCM detects a malfunction or inconsistency in the communication signals from sensors or modules within the vehicle. Commonly found in models such as the 2015-2018 Honda Accord and some Ford vehicles, the C06FC code can lead to various operational issues if not addressed. Symptoms may include the malfunction of interior lights, power windows, or even issues with the vehicle's locking system. If the code is not resolved, drivers might experience increased electrical drain on the battery, leading to potential starting issues. Moreover, ignoring this code can escalate to more severe problems that might affect the overall driving experience and safety, making it crucial for owners to understand and resolve these issues promptly.

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

Symptoms

Common symptoms when C06FC is present:

  • The check engine light illuminates and remains on, indicating a persistent issue with the vehicle's systems.
  • Interior lights may flicker or fail to operate, affecting visibility and comfort inside the vehicle.
  • Power windows may operate intermittently or fail to respond, limiting driver control over vehicle functions.
  • The vehicle may experience difficulty in locking or unlocking doors, raising security concerns.
  • Battery drain occurs due to the BCM's failure to enter sleep mode, leading to potential starting problems.

Possible Causes

Most common causes of C06FC (ordered by frequency):

  1. The most common cause of code C06FC is a faulty body control module, responsible for managing various electrical functions, with a likelihood of about 60%.
  2. Another cause could be damaged wiring or poor connections between the BCM and other components, which can disrupt communication signals.
  3. Corrosion on terminals or connectors, especially in older vehicles or those exposed to moisture, can lead to communication failures; regular inspections can help prevent this.
  4. A less common but serious cause is software glitches in the BCM, which may require a software update or complete replacement of the module.
  5. In rare cases, interference from aftermarket electronic devices installed in the vehicle can also trigger this code.
