About P0586

P0586 is a generic (obd-ii standard) powertrain diagnostic trouble code. It belongs to the P-prefix family of codes, which covers engine, transmission, emissions, or fuel-system faults.

When P0586 is stored, the module has detected an open (broken or disconnected) electrical path in the monitored circuit.

Scanning & clearing: A generic OBD-II scan tool will usually read and clear powertrain (P) codes. For live data, freeze-frame capture, and bi-directional tests you may need a more capable scan tool that supports the vehicle's ECM protocol.

Because P0586 is a generic OBD-II code, its base definition is shared across manufacturers. The specific diagnostic steps, reference values, and repair procedures can vary by vehicle, and the TaT Diagnostic Assistant includes verified procedures submitted by working technicians.

Code Information

This fault code is set when the engine control module (ECM) or the body control module (BCM) detects an open circuit condition in the cruise control vent solenoid circuit. The cruise control vent solenoid plays a critical role in the operation of the cruise control system, particularly in vehicles with vacuum-controlled cruise control systems. It helps regulate the vacuum to the cruise control actuator. An open circuit indicates a lack of continuity, which can disrupt the proper functioning of the solenoid, leading to issues with engaging, disengaging, or maintaining the set speed in the cruis...
