Common Questions

What does B0C55 mean and how does it affect my car?

The B0C55 code indicates a malfunction in your vehicle's advanced driver-assistance systems (ADAS). This could affect features like adaptive cruise control or lane-keeping assist, potentially compromising your safety while driving. It's essential to address this issue promptly.

What are the most common causes of B0C55 and how much does it cost to fix?

Common causes include faulty power supply, wiring issues, and software glitches. Repair costs can range from $100 for minor repairs to $600 for sensor replacements, depending on the specific issue.

Can I drive my car with B0C55 or should I stop immediately?

While you may be able to drive with the B0C55 code, it's not advisable. The code indicates issues with safety features. It's best to have the vehicle inspected as soon as possible to prevent potential accidents.

How can I diagnose B0C55 myself using GeekOBD APP?

Using the GeekOBD APP, you can scan for the B0C55 code and any related codes. Make sure to inspect the wiring and connectors, check the voltage at the ADAS components, and clear the codes to see if they return after repairs.

What vehicles are most commonly affected by B0C55?

The B0C55 code is frequently found in vehicles equipped with ADAS technologies, particularly in models like the 2016-2021 Ford Explorer and certain Lincoln models. Always check for recalls or technical service bulletins (TSBs) related to these systems.

How can I prevent B0C55 from happening again?

To prevent the B0C55 code from reoccurring, ensure regular maintenance checks on your vehicle's electrical system, keep wiring and connections clean and dry, and stay updated with software for your vehicle's systems.

What is B0C55?

The DTC B0C55 code indicates a fault in the vehicle's advanced driver-assistance system (ADAS), particularly related to the power supply or communication issues between components like the camera or sensors. When this code appears, it typically suggests that the system responsible for features such as lane-keeping assist, adaptive cruise control, or collision avoidance may not be functioning correctly. This can lead to a reduction in safety features, potentially increasing the risk of accidents. If you're driving a newer model like the 2016-2021 Ford Explorer, this code is particularly relevant, as these vehicles are equipped with sophisticated ADAS technologies. Ignoring this code may not only compromise your vehicle's safety features but can also lead to more extensive repairs if the underlying issues are not addressed promptly. It's crucial to understand that while the check engine light may not illuminate, the B0C55 code should still be taken seriously and diagnosed as soon as possible.

Symptoms

Common symptoms when B0C55 is present:

  • The dashboard warning light for the ADAS systems stays illuminated, indicating a system fault.
  • Drivers may experience intermittent failures of features like adaptive cruise control, which may disengage unexpectedly.
  • You may notice a reduced ability for lane-keeping assist to function, causing the vehicle to drift without proper steering assistance.
  • In some cases, the vehicle may exhibit erratic behavior in braking systems, creating potential safety hazards.
  • The infotainment system may occasionally freeze or provide incorrect information regarding ADAS system status.

Possible Causes

Most common causes of B0C55 (ordered by frequency):

  1. The most common cause of the B0C55 code is a faulty power supply to the ADAS components, with a likelihood of about 50%. This could stem from a weak battery or poor connections.
  2. Faulty wiring or harness issues represent the second most common cause, at around 30%. This often occurs due to wear and tear or exposure to moisture.
  3. Software glitches in the vehicle's control modules can also trigger the B0C55 code, accounting for about 15% of cases. Regular updates and maintenance can help prevent this.
  4. Less commonly, a malfunctioning camera or sensor may be to blame, which can be a more expensive repair if replacement is necessary.
  5. Rarely, issues with the vehicle's central computer or integrated modules could lead to the B0C55 code, necessitating advanced diagnostic tools to pinpoint.
