What is C03B1?

DTC C03B1 is a diagnostic trouble code that indicates a problem within the vehicle's advanced driver-assistance systems (ADAS), specifically related to the radar sensor signal. This code often appears in models like the 2015-2018 Ford Edge, but can also be seen in various other vehicles equipped with similar ADAS technology. The radar sensor is responsible for detecting objects and measuring distances, which is crucial for features like adaptive cruise control and forward collision warning. When the vehicle's onboard computer registers an issue with the radar signal, it triggers the C03B1 code. The real-world implications of this code manifest as malfunctions in the vehicle's safety features, which can compromise safety and driving assistance capabilities. The presence of this code may also illuminate warning lights on the dashboard, alerting drivers to the issue. Ignoring this code might lead to more significant problems down the line, including potential safety risks. If your vehicle is experiencing this code, it’s essential to address it promptly to ensure all safety features are functioning correctly.

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

Symptoms

Common symptoms when C03B1 is present:

  • The warning light for the advanced driver assistance system stays illuminated, indicating a malfunction.
  • Drivers may notice that adaptive cruise control is unresponsive or does not engage, leading to inconsistent speed control.
  • There may be a failure in collision warning alerts, which can increase the risk of accidents.
  • Unexpected vehicle braking without driver input may occur, causing concern and confusion while driving.
  • Inconsistent performance from parking assist systems, leading to difficulty in maneuvering the vehicle.

Possible Causes

Most common causes of C03B1 (ordered by frequency):

  1. The most common cause of C03B1 is a malfunctioning radar sensor, accounting for approximately 60% of cases. This could be due to physical damage or misalignment.
  2. A second common cause is wiring issues, including frayed wires or poor connections, which can disrupt the radar sensor's communication with the vehicle's computer.
  3. Contamination on the radar sensor lens, such as dirt or debris, can impair its functionality. Regular cleaning can help prevent this issue.
  4. Less commonly, software glitches within the vehicle’s ADAS programming can lead to false C03B1 readings. Regular software updates can mitigate this risk.
  5. A rare but possible cause is a complete failure of the vehicle's control module associated with the radar system, which would require replacement.
