Common causes of P0586 include a faulty cruise control switch, wiring issues, or problems with the ECM. Repair costs can range from $50 for wiring repairs to $300 for ECM reprogramming, depending on the underlying issue.
Can I drive my car with P0586 or should I stop immediately?
While you may be able to drive with the P0586 code, it is advisable to address it promptly. Driving with a malfunctioning cruise control can be distracting and may lead to unsafe driving conditions, especially on long trips.
How can I diagnose P0586 myself using GeekOBD APP?
Using the GeekOBD APP, start by connecting it to your vehicle's OBD2 port. Run a full diagnostic scan to retrieve the P0586 code and any related codes. Pay attention to freeze frame data that shows the vehicle's condition when the code was triggered, helping you pinpoint the issue.
What vehicles are most commonly affected by P0586?
Vehicles like the 2015-2018 Ford F-150 and the 2012-2016 Honda Accord frequently experience the P0586 code due to their electronic cruise control systems. Check for any recalls or technical service bulletins related to these models.
How can I prevent P0586 from happening again?
Regularly inspect your vehicle's wiring and cruise control components for wear and tear. Keeping the electrical connections clean and dry can prevent corrosion. Additionally, ensure that your vehicle receives routine maintenance checks to catch potential issues early.
What is P0586?
DTC P0586 is a diagnostic trouble code that indicates a problem with the cruise control switch input A, specifically relating to its range or performance. This issue typically arises in vehicles equipped with electronic cruise control systems, which are designed to maintain a steady speed without the driver needing to keep their foot on the accelerator. When the system detects that the input from the cruise control switch is out of range or not performing as expected, it triggers this fault code. This can impact the overall driving experience, as the cruise control system may become inoperative, potentially forcing the driver to maintain speed manually. Common makes and models affected by P0586 include the 2015-2018 Ford F-150 and the 2012-2016 Honda Accord. If left unaddressed, this issue can lead to increased driver fatigue and may pose a safety risk during long drives. It's essential to diagnose and repair this fault to restore proper functionality to your vehicle's cruise control system.
System: P - Powertrain (Engine, Transmission, Emissions)
Symptoms
Common symptoms when P0586 is present:
- Check engine light remains illuminated consistently, indicating an ongoing issue with the cruise control system.
- Cruise control system fails to engage, causing frustration during long drives where speed maintenance is desired.
- The vehicle may unexpectedly accelerate or decelerate, leading to unpredictable driving behavior.
- Driver experiences increased fatigue from having to maintain speed manually during long trips.
- In rare cases, a temporary loss of the speedometer may occur, complicating speed management.
Possible Causes
Most common causes of P0586 (ordered by frequency):
- The most common cause of P0586 is a faulty cruise control switch, occurring in approximately 60% of cases. This switch may wear out or become damaged, leading to improper signaling to the vehicle's control module.
- Another frequent cause involves wiring issues, such as frayed or corroded wires that connect the cruise control switch to the vehicle's computer system. These can disrupt the signal and result in faulty readings.
- Thirdly, a malfunctioning engine control module (ECM) can lead to the P0586 code, though this is less common. Regular software updates and diagnostics can help prevent this issue.
- A less common but severe cause could be a problem with the vehicle's throttle control system, which may require immediate attention to ensure safety.
- Rarely, there might be an issue with the internal programming of the cruise control system that requires professional reprogramming or replacement of the ECM.
