What is U01C6?
The U01C6 diagnostic trouble code (DTC) indicates a communication error in the vehicle’s network, specifically related to the vehicle's Advanced Driver Assistance Systems (ADAS). This code is prevalent in various Ford models, including the Ford F-150, Explorer, and Escape from model years 2016 to 2022. When U01C6 is triggered, it usually means that the control module responsible for the ADAS is unable to communicate with other modules in the vehicle network, which can affect features like lane-keeping assist, adaptive cruise control, and collision avoidance systems. The implications of this code can be serious; it may lead to the complete failure of these critical safety features, potentially putting the driver and passengers at risk. As such, it is essential for vehicle owners to address this code promptly. Ignoring it can not only compromise vehicle safety but also lead to more extensive and costly repairs down the line. If you’ve encountered U01C6, it is advisable to have your vehicle inspected by a qualified technician who can diagnose the issue accurately and recommend appropriate repairs.
System: U - Network (Communication, CAN Bus)
Symptoms
Common symptoms when U01C6 is present:
- The check engine light illuminates, indicating a problem in the vehicle's communication system.
- The adaptive cruise control feature becomes non-functional, creating challenges during highway driving.
- Lane-keeping assist may intermittently disengage, leading to potential safety hazards.
- The vehicle may experience erratic behavior in electronic systems, such as unexpected warnings.
- Reduced fuel efficiency may occur due to the engine management system being compromised.
Possible Causes
Most common causes of U01C6 (ordered by frequency):
- The most common cause of U01C6 is water intrusion in the ADAS control module, occurring in approximately 40% of cases. This can happen due to poor sealing or damage to the vehicle's outer body.
- A second cause is damaged wiring or connectors in the communication harness, which can lead to intermittent or complete loss of signal. This is often due to wear and tear or improper installation during previous repairs.
- Another potential cause is module failure, where the ADAS control module itself malfunctions, which can be exacerbated by electrical surges or software issues.
- Less common, but serious, is a fault in the vehicle's main computer that can affect multiple systems, leading to widespread failures.
- A rare but possible cause could be factory recalls or service bulletins that have not been addressed, which can affect the vehicle's software.
