The first 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.

• After recording the active P0576 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
• Carefully test the cruise control switch. Refer to your make and model 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
• 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
