What are the steps to diagnose the cruise control issue in a 2025 Toyota Prius AWD-e?

When diagnosing a cruise control issue in a 2025 Toyota Prius AWD-e, it's crucial to follow a methodical approach that prioritizes simpler checks before delving into more complex diagnostics. Begin by inspecting the cruise control fuse, as a blown fuse can easily disrupt the system's functionality. Next, examine the cruise control buttons on the steering wheel for any signs of sticking or malfunction, which could impede proper operation. Utilizing an OBD-II scanner to check for error codes is essential, as these codes can reveal specific issues within the cruise control system. Additionally, ensure that the speed sensors are functioning correctly, as they play a vital role in the system's performance. It's also wise to inspect the wiring connections for any damage or corrosion that may affect communication within the system. Finally, test the cruise control module to confirm it is operating as intended. If these steps do not resolve the issue, consulting a professional mechanic or an authorized Toyota service center is recommended for further assistance. By adhering to this structured diagnostic approach, you can effectively identify and troubleshoot cruise control problems in your vehicle.
