Common Questions

What does C0C64 mean and how does it affect my car?

C0C64 signifies a communication error between the Body Control Module and Integrated Control Module. This can lead to various electrical issues, potentially affecting critical systems like lighting and door locks. If left unresolved, it may lead to more severe problems, including complete electrical failure and safety hazards while driving.

What are the most common causes of C0C64 and how much does it cost to fix?

The most common causes of C0C64 include a faulty Body Control Module (BCM), wiring issues, and software glitches. Repair costs can range from $100 for a simple software update to $600 for BCM replacement, depending on the specific issue found.

Can I drive my car with C0C64 or should I stop immediately?

While you might be able to drive your car with C0C64, it's not advisable. The communication failure can impact essential functions, posing safety risks. It's best to have your vehicle diagnosed and repaired as soon as possible to ensure safe operation.

How can I diagnose C0C64 myself using GeekOBD APP?

To diagnose C0C64 with the GeekOBD APP, first connect the device to your vehicle's OBD2 port. Use the app to scan for codes, retrieve freeze frame data, and observe any patterns or additional codes that may provide insight into the issue. This step helps you understand the context of the problem before taking further action.

What vehicles are most commonly affected by C0C64?

C0C64 is commonly seen in 2015-2018 Honda Civics, among other models. It's advisable to check for any recalls or Technical Service Bulletins (TSBs) related to electrical issues in your vehicle to stay informed about potential problems.

How can I prevent C0C64 from happening again?

To prevent C0C64 from recurring, regularly inspect your vehicle's wiring and connections, keep the BCM and ICM software updated, and maintain your vehicle's electrical system through routine check-ups. Investing in a quality diagnostic tool like the GeekOBD APP can also help you catch issues early.

What is C0C64?

The Diagnostic Trouble Code (DTC) C0C64 indicates an issue within the vehicle's network communication system, particularly related to the Body Control Module (BCM) or communication with the Integrated Control Module (ICM). This code is prevalent in various models, especially the 2015-2018 Honda Civic, and it can lead to multiple electrical issues if not addressed. When the C0C64 code is triggered, it typically signifies that the BCM is not receiving the correct signals from the ICM, which can disrupt functions such as the vehicle's lighting, door locks, and other essential electronic features. In simpler terms, if you notice your car's lights not responding as they should or if electronic components behave erratically, this could be a sign that the C0C64 code is present. Ignoring this code can lead to more significant issues, such as complete electrical failure or safety hazards while driving. It’s essential to diagnose the problem promptly, as the longer it persists, the more complicated and costly the repairs may become. Understanding this code is crucial for maintaining the functionality and safety of your vehicle, particularly for those who rely on their car's electronic systems.

Symptoms

Common symptoms when C0C64 is present:

  • Check engine light remains illuminated, indicating a persistent issue that needs attention.
  • Power windows may malfunction, either failing to operate or operating erratically.
  • Keyless entry system may stop working, making it difficult to lock or unlock doors remotely.
  • Dashboard lights may flicker or display incorrect information, leading to confusion about vehicle status.
  • Interior lights may not turn on or off as expected, complicating nighttime driving.

Possible Causes

Most common causes of C0C64 (ordered by frequency):

  1. Faulty Body Control Module (BCM) - 40% likelihood. The BCM manages various electrical systems, and if it malfunctions, it can trigger C0C64.
  2. Wiring issues or poor connections - 30% likelihood. Damaged or corroded wiring can interrupt communication between modules.
  3. Software glitches in the BCM or ICM - 20% likelihood. Sometimes, a simple software update can resolve communication issues.
  4. Less common cause: Short circuit in the vehicle's electrical system - 5%. This can lead to multiple fault codes and requires in-depth diagnostics.
  5. Rare but possible: Corrupted data in the vehicle's computer systems - 5%. This scenario often necessitates a full system reset or replacement of components.
