Error Code P0575: What It Means & What To Do?

<<See All OBD Codes

The error code P0575 can be identified as Cruise Control Input Circuit.

The P0575 code would indicate that the powertrain control module has detected that the control input circuit is suffering from an electrical malfunction.

Now if the powertrain control module would detect an issue with the cruise control system, it will run a self-instituted test of the system. If there is an abnormal voltage/resistant result within the cruise control input circuit, then it would start triggering up the P0575 trouble code.

What causes this problem with the Cruise Control Input Circuit?

• There can be an internal short, open, etc in the engine control module
• Open or shorted cruise control function switch
• Defective connectors within the cruise control system
• A common cause of abnormal voltage/resistance level in the cruise control input circuit is a defective cruise control switch that could potentially be caused by spilled liquids that short circuits the device and/or circuits within
• There can be some issues related to the wiring
• Issue of blown fuses which might indicate a much more serious problem

It is essential to know the symptoms of an issue as only then you would be able to solve the problem. So that’s why we have listed out some major symptoms of OBD Code P0575 here:

Common Symptoms

• Illumination of the check engine light within a few drive cycles after the ECM has detected that there's an issue
• Cruise control light might be on constant or it might not come on
• There might be erratic or intermittent cruise control function operation

If you wish to correct this fault code, then you have to follow certain steps. Correcting a problem needs your careful attention. Here are some ways with the help of which you will be able to correct the OBD Code P0575:

• Carefully replace the defective cruise control switch
• If there are any fluid leaks due to which the switch is malfunctioning, the it should be repaired
• Repair or replace the shorted or open wiring
• The open or shorted cruise control function switch harness should be repaired properly
• Restore the damaged connectors within the cruise control system
• Make sure to replace the blown fuses

If you want to easily diagnose this trouble code, then you must follow the steps which are mentioned here as below:

The first and the foremost step in the troubleshooting process for any malfunction is to research the technical service bulletins for known issues. Advanced diagnostic steps become very vehicle specific and may require the appropriate advanced equipment and knowledge to perform accurately. We include basic steps below but refer to a vehicle year/make/model/powertrain specific repair guide for specific steps for your vehicle.

Step 1

After recording the active P0575 code with your OBD-II DTC scanner, you should conduct an in-depth inspection of the vehicle's connectors, wirings, and other parts of the cruise control system. It is also important that any damaged connectors (e.g. broken tabs, heat damage, corroded, etc.) be replaced, reconnected, or repaired as necessary. You will need to clear the code and perform a sort test drive, try using the cruise control functions now. If everything is working after the repair, you should ensure that the check engine light no longer reappears. Otherwise, if it does light up again and the code has been stored in the ECM once more, continue your diagnostics.

Step 2

Carefully test the cruise control switch. Refer to your make and model's service manual to acquire the correct desired values and diagnostic procedures specific to your vehicle. Most times, this will involve using your DVOM or multimeter to record the electrical values present. After comparing your actual values to the manufacturer's desired ones, you will be able to pinpoint the switch as the issue or rule out as a possibility.

Step 3

If you find out that there are some faults in the switch, replacing it may not be an easy task, given the fact that there may be airbags in the way of replacing it. It could be as simple as removing 1 or 2 steering column covers to access the switch. If you've pinpointed it as your problem, found it to be defective and replaced it following the specific steps unique to your vehicle, test drive the vehicle once the codes have been cleared up

Common Mistakes When Diagnosing The P0575 Code

When diagnosing the underlying cause of the P0575 code, one of the most common mistakes made is to replace several components unnecessarily when the problem was actually a blown fuse. It’s important to check for blown fuses before replacing any components, and then to perform a test to see if the fuse was causing the issue
