Code P1585 Description
The P1585 diagnostic trouble code (DTC) indicates an issue with the cruise control inhibit output circuit conditions in the vehicle. Cruise control is a system that allows a vehicle to maintain a constant speed without the driver needing to continually press the accelerator pedal. In modern vehicles, the cruise control system is controlled electronically, and the inhibit output circuit plays a crucial role in enabling or disabling the cruise control function.
Common Causes of P1585
- Faulty cruise control module
- Damaged wiring or connectors in the inhibit output circuit
- Corrosion or poor connections in the circuitry
- Electronic control unit (ECU) issues affecting cruise control
- Faulty brake switch or clutch switch preventing cruise control engagement
Symptoms of P1585
- Inoperative cruise control system
- Inability to set or maintain a constant speed
- Illumination of the cruise control warning light on the dashboard
- Erratic behavior of the cruise control system
- Loss of power or acceleration while using cruise control
How to Fix P1585
- Perform a thorough visual inspection of the cruise control wiring and connectors to check for any obvious damage or loose connections.
- Use a multimeter to test the continuity and voltage of the inhibit output circuit to identify any faults or open circuits.
- Check and test the cruise control module for proper operation and communication with the vehicle's ECU.
- Inspect and test the brake switch and clutch switch to ensure they are functioning correctly and not inhibiting the cruise control system.
- Clear the DTC from the vehicle's ECU memory after making any necessary repairs and test the cruise control system to ensure proper functionality.
Cost to Fix P1585
The typical repair costs for addressing the P1585 code related to cruise control inhibit output circuit conditions can vary depending on the specific cause of the issue and the labor rates in your location.
