This summary uses the existing diagnostic information shown in full below.
This means that the car's computer has detected a problem with a part of the cruise control system. It's like when a button on a remote control doesn't work because the battery is low or the button is stuck.
The P0592 code indicates that the cruise control system has detected a low voltage or short in the input circuit B, which is responsible for receiving signals to control the cruise control functions.
The cruise control system uses multiple circuits to receive and process inputs from the driver, such as setting speed or disengaging the system. Circuit B is one of these input circuits, and a low voltage condition suggests a short to ground or a failure in the circuit's ability to carry the necessary electrical signals.
• Cruise control not engaging
• Cruise control disengages unexpectedly
• Warning light on the dashboard
• Faulty cruise control switch
• Damaged wiring or connectors in the circuit
• Blown fuse related to the cruise control system

This code has been associated with issues in vehicles with electronic cruise control systems, particularly in models from the early 2000s.
Moderate – The vehicle can still be driven, but the cruise control feature may not work properly.
Operating a vehicle with a malfunctioning cruise control system may lead to unexpected acceleration or deceleration, which can be a safety hazard.
• Vehicle must be in motion.
• Cruise control system must be activated.
The cruise control switch is typically located on the steering wheel or steering column.
Q: Can I drive my car with this code?
A: Yes, but the cruise control feature may not work properly.
Q: Will this code affect my car's performance?
A: It should not affect the overall performance of the car, but the cruise control function may be disabled.
