What is C01D2?

The DTC C01D2 code indicates a fault within the vehicle's advanced driver-assistance systems (ADAS), specifically relating to the vehicle's sensors and their communication with the control module. This code can manifest in various ways, including issues with parking sensors, lane departure warnings, or adaptive cruise control features. When this code is triggered, it typically means that the vehicle's onboard computer has detected a significant issue with the sensor inputs or the system responsible for processing this data. For example, in a 2016 Ford F-150, drivers may notice that the adaptive cruise control feature fails to engage or disengages unexpectedly, leading to potential safety concerns. Additionally, the check engine light may illuminate on the dashboard, prompting an early investigation into the vehicle's electronic systems. Ignoring this code could lead to further complications and safety risks, as critical safety features may not function as intended. Overall, it's essential to address the C01D2 code promptly to ensure the proper functioning of the vehicle's safety systems and avoid potential hazards on the road.

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

Symptoms

Common symptoms when C01D2 is present:

  • The check engine light is illuminated, indicating a fault in the vehicle's electronic systems.
  • Adaptive cruise control intermittently fails to engage, impacting driving safety and convenience.
  • Parking sensors provide erroneous readings or stop functioning altogether, leading to potential accidents during parking.
  • Lane departure warning systems show inconsistent alerts, making it crucial to assess steering and lane-keeping assistance.
  • The vehicle experiences frequent system resets or errors in other ADAS functionalities, indicating broader electrical issues.

Possible Causes

Most common causes of C01D2 (ordered by frequency):

  1. The most common cause of the C01D2 code is a faulty sensor, with a likelihood of around 40%. This can be due to physical damage or corrosion.
  2. Another frequent reason is wiring issues, such as short circuits or damaged connectors, which can prevent proper communication between sensors and the control module.
  3. Software glitches or outdated firmware in the vehicle’s ECU can also trigger this code, making regular updates essential for functionality.
  4. Less commonly, a malfunctioning control module itself can be the root cause, which often requires replacement and can be costly.
  5. A rare but possible cause includes environmental factors, such as extreme temperatures affecting sensor performance.
