P0580

DTC P0580, sometimes indicated as P058000 is an OBD diagnostic trouble code indicating a generic fault with the vehicle powertrain (i.e. engine and gearbox). This code identifies an error with the engine idling stability causing cruise control multi-function input "a" circuit low.

This code indicates that the cruise control system is not getting a signal from the brake pedal. This could be caused by a defective brake pedal switch, a wiring problem, or a problem with the cruise control system itself.
If you have this code, first check the brake pedal switch for continuity. If it's good, check the wiring for any damage or corrosion. If the wiring is good, then the problem is probably with the cruise control system.
