What is C0BD1?

The DTC code C0BD1 indicates a problem with the vehicle's advanced driver-assistance systems (ADAS) related to the steering or braking systems. This code is particularly common in vehicles such as the 2016-2021 Ford Explorer and other models equipped with electronic stability control (ESC) and lane-keeping assist features. When the C0BD1 code is triggered, it usually signifies a communication fault between the steering control module and the vehicle's main computer system. Drivers may notice that advanced safety features such as lane departure warnings or automatic emergency braking may not function as intended. Ignoring the C0BD1 code can lead to decreased vehicle safety, as these features are designed to prevent accidents and improve vehicle handling. Additionally, the code can cause the check engine light to illuminate, prompting a need for immediate diagnostic attention. It's crucial to address this code promptly to ensure the safety features of your vehicle are operational and to avoid further damage to the steering or braking systems.

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

Symptoms

Common symptoms when C0BD1 is present:

  • The check engine light stays on constantly, alerting you to a potential issue with the vehicle's safety features.
  • You may experience a reduction in the vehicle's stability control functionality, making it harder to maintain control during adverse weather conditions.
  • Drivers might feel a noticeable delay or lack of responsiveness from the steering wheel, affecting the overall handling of the vehicle.
  • Automatic emergency braking may not engage when needed, which can increase the risk of collisions.
  • Lane departure warnings may not activate, leaving you unaware of potential lane drift.

Possible Causes

Most common causes of C0BD1 (ordered by frequency):

  1. The most common cause of the C0BD1 code is a faulty steering angle sensor, which occurs in approximately 40% of cases. This sensor helps the vehicle's computer understand the steering wheel's position and can fail due to wear or damage.
  2. Another common culprit is a wiring issue, such as frayed wires or poor connections, which can lead to communication failures between the steering module and the vehicle's computer. This accounts for about 30% of cases.
  3. In some instances, a malfunctioning electronic control module (ECM) may be the cause, which can disrupt the entire system's functioning. Regular software updates can help prevent these issues.
  4. Less commonly, issues with the vehicle's braking system, such as a faulty ABS module, may trigger the C0BD1 code and require immediate attention.
  5. A rare but possible cause is interference from aftermarket electronic installations that can disrupt the signals between the steering and braking systems.
