The engine fault code P0585 refers to a problem with the cruise control system, specifically related to the multi-function input A/B correlation. This means that the vehicle`s computer is detecting an inconsistency between the signals from the cruise control switches or inputs.
Heres a breakdown of what it could indicate:
1. Cruise Control Switch Issue: The switches that control the cruise control might be faulty or not sending the correct signals.
2. Wiring Problems: There could be damaged wiring or poor connections in the cruise control system, causing incorrect readings.
3. Faulty Engine Control Module (ECM): In some cases, the ECM itself might have a problem interpreting the signals from the cruise control system.
4. Sensor Malfunction: The sensors involved in the cruise control system could be malfunctioning, leading to the correlation error.
Alternative Meanings by Manufacturer
While P0585 generally indicates the same issue across different manufacturers, the specifics can vary:
– Porsche: May indicate a specific problem with the cruise control module or related wiring.
– Mini: Might be associated with the multi-function steering wheel controls.
– Mercedes-Benz: Could involve more complex systems like Distronic, which is their adaptive cruise control.
– Audi: Similar to Volkswagen, it might relate to the steering wheel controls or the adaptive cruise system.

The Engine Fault Code P0585 typically relates to a problem with the cruise control system in your vehicle. This code indicates that theres an issue with the correlation between the multi-function input A and B, which usually refers to the signals sent from the cruise control switches.
Here are some common causes for this code across various manufacturers:
1. Faulty Cruise Control Switch: The switch that controls the cruise function may be malfunctioning or have a poor connection.
2. Wiring Issues: Damaged or corroded wiring between the cruise control switch and the engine control unit (ECU) can cause signal problems.
3. Faulty ECU: The engine control unit itself may have a fault that affects how it reads the cruise control signals.
4. Sensor Problems: Issues with related sensors, such as the throttle position sensor, can also trigger this code.
5. Software Glitches: In some cases, a software update may be needed to resolve the issue.
6. Mechanical Issues: Problems with the throttle body or other components linked to the cruise control system can lead to this code.
7. Manufacturer-Specific Variations: Different brands may have unique components that can affect the cruise control system. For example:
– Porsche: Issues with the multifunction steering wheel controls.
– Mini: Potential problems with the connection to the ABS module, which can affect cruise control.
– Mercedes: May involve issues with the steering column module or wiring harness.
– Audi: Could be related to the vehicle`s drive-by-wire system.
– Jaguar: Might include problems with the adaptive cruise control sensors.
– Land Rover: Could involve issues with the Terrain Response system affecting cruise functionality.
If you encounter this code, it`s best to perform a thorough inspection of the cruise control system, check for any fault codes, and test the components involved.
The Engine Fault Code P0585 relates to the cruise control system, specifically indicating a problem with the multi-function input A/B correlation. This means that the cruise control system is not receiving the expected signals from the controls. Heres how to troubleshoot and fix this issue for European cars like Porsche, Mini, Mercedes, Audi, Jaguar, and Land Rover:
General Steps to Fix P0585:
1. Check the Cruise Control Switch:
– Inspect the cruise control switch for any visible damage or wear.
– Ensure that the switch is connected properly. If it`s loose or damaged, it may need to be replaced.
2. Inspect Wiring and Connectors:
– Look for damaged, frayed, or corroded wires in the cruise control circuit.
– Check connectors for corrosion or poor connections. Clean or repair as necessary.
3. Scan for Other Codes:
– Use an OBD-II scanner to check for any other related trouble codes. Sometimes, multiple codes can give a clearer picture of the issue.
4. Test the Brake Pedal Switch:
– The cruise control system often relies on the brake pedal switch. Ensure it is functioning properly. If it`s faulty, replace it.
5. Check the Clutch Pedal Switch (if applicable):
– For vehicles with a manual transmission, the clutch pedal switch can also affect cruise control. Test and replace if needed.
6. Inspect the Throttle Position Sensor:
– The throttle position sensor (TPS) can affect cruise control operation. Check its functionality and replace it if its not working correctly.
7. Look for Software Issues:
– Some vehicles may require a software update for the cruise control system. Check with the dealer or a qualified mechanic.
8. Perform a System Reset:
– After making repairs, clear the fault codes using an OBD-II scanner and see if the code returns.
Manufacturer-Specific Notes:
– Porsche:
– Check for specific software updates related to the cruise control system.
– Mini:
– The multi-function steering wheel may need calibration or replacement if its malfunctioning.
– Mercedes:
– Some models may have a separate module for cruise control. Check for faults in that module.
– Audi:
– Audi vehicles may have additional features like adaptive cruise control, which could complicate diagnostics. Pay attention to those systems.
– Jaguar:
– Jaguar may have unique wiring harnesses that can be prone to issues. Inspect them closely.
– Land Rover:
– Check for known issues with the cruise control system in the specific model year, as some may have recalls or common problems.
Fixing the P0585 code involves a systematic approach to checking the cruise control components and wiring. If youre not comfortable with these checks, it might be best to consult a professional mechanic. Always remember to clear the codes after repairs and test drive the vehicle to ensure the issue is resolved.
Driving with a P0585 code, which indicates a problem with the cruise control multi-function input, is generally not recommended. This code means that there`s a correlation issue between the cruise control switch inputs. Heres a breakdown of what it might mean for different manufacturers:
1. Porsche: If this code appears, it could affect your ability to use cruise control. While the car is still safe to drive, you should address the issue soon to avoid potential problems with acceleration control.
2. Mini: For Mini vehicles, a P0585 code might not directly affect safety, but it can lead to issues with speed control. It`s best to get it checked to ensure everything is functioning properly.
3. Mercedes: In Mercedes vehicles, this code could indicate a malfunction in the cruise control system. While you can still drive safely, the cruise control wont work, which can be inconvenient on long drives.
4. Audi: Audi cars with this code may experience similar issues. While the car remains drivable, you should have it diagnosed to prevent further complications.
5. Jaguar: For Jaguar models, a P0585 code could lead to problems with cruise control functionality. It`s safe to drive, but you should consider having it inspected.
6. Land Rover: In Land Rover vehicles, this code may not impact overall safety but can disable the cruise control. It`s advisable to have it checked to ensure optimal performance.
Our take, while its usually safe to drive with a P0585 code, you should address the issue soon to ensure your cruise control works properly and to avoid any potential complications.
