The P0585 OBD-II code indicates a problem with the cruise control system of your vehicle. This code is triggered when the engine control module (PCM) detects a discrepancy between the signals from the multi-function input switches for the cruise control, specifically the “A” and “B” inputs.
What Does the P0585 Code Mean?
The P0585 code signifies that there is a correlation issue between the cruise control multi-function inputs. When the PCM receives signals from more than one switch at the same time, it disables the cruise control system and sets this fault code.
What Causes the P0585 Code?
Several factors can trigger the P0585 code, including:
- Cruise control switch failure
- Powertrain Control Module (PCM) failure
- Wiring issues related to the cruise control system
What Are the Symptoms of the P0585 Code?
When the P0585 code is present, the primary symptom you will experience is that the cruise control will not operate. This can be frustrating, especially on long drives where cruise control is often utilized for comfort.
How Serious Is the P0585 Code?
The P0585 code is classified as a moderate severity issue. While it may not pose an immediate threat to your vehicle’s safety or functionality, it is important to address it promptly to avoid further complications with your cruise control system.
How to Diagnose the P0585 Code
Diagnosing the P0585 code typically involves the following steps:
- Use an OBD-II scanner to confirm the presence of the P0585 code.
- Inspect the cruise control switches for any visible damage or wear.
- Check the wiring and connections for any signs of corrosion or fraying.
- Test the functionality of the cruise control switch and related components.
- If necessary, perform further diagnostics on the Powertrain Control Module (PCM).
Common Repairs for the P0585 Code
Repairs for the P0585 code may include:
- Replacing faulty cruise control switches
- Repairing or replacing damaged wiring
- Reprogramming or replacing the Powertrain Control Module (PCM)
How Much Does It Cost to Fix the P0585 Code?
The cost to fix the P0585 code can vary significantly based on the specific repairs needed. On average, you might expect to spend anywhere from $100 to $400, depending on whether you need to replace switches, wiring, or the PCM.
Can I Fix the P0585 Code Myself?
If you have basic automotive knowledge and access to the right tools, you may be able to troubleshoot and fix the P0585 code yourself. However, if the issue involves complex components like the PCM, it is advisable to seek professional assistance to ensure proper diagnosis and repair.
