2013 Subaru BRZ Cruise Control Isn't Working

To effectively diagnose the non-functioning cruise control in your 2013 Subaru BRZ, start with a systematic approach that prioritizes simpler checks before delving into more complex issues. Begin by connecting an OBD-II scanner to your vehicle to retrieve any stored error codes, as these can provide valuable insights into the underlying problem. Next, inspect the electrical components, particularly the fuses associated with the cruise control system; replacing a blown fuse may resolve the issue. Following this, examine the brake and clutch switches, ensuring they are operational since these components play a critical role in disengaging the cruise control when necessary. If these initial checks do not yield results, investigate the control module and throttle actuation system, as failures in these areas are common culprits for cruise control malfunctions. For vehicles equipped with adaptive cruise control, ensure that any cameras are clean and functioning properly, as obstructions can disable the system. Finally, conduct a thorough physical inspection of the wiring and connections for any signs of damage or corrosion. By following this structured diagnostic approach, you can efficiently identify the cause of the cruise control issue and determine whether further professional assistance is needed.

When troubleshooting cruise control issues in a 2013 Subaru BRZ, it's essential to consider several common problems that may be at play. Start by inspecting the cruise control fuse located in the fuse box; a blown fuse can often be a simple fix that restores functionality. Next, examine the various sensors and switches involved in the system, such as the speed sensor, brake pedal switch, and clutch sensor. A malfunction in any of these components can prevent the cruise control from engaging, especially if the speedometer is also acting erratically. Additionally, issues with the throttle actuation system, which regulates engine speed, can lead to cruise control failure. If these components check out, the control module itself may be the culprit, as it is vital for the electronic operation of the cruise control system. Don't overlook potential electrical or wiring problems, as these can disrupt the entire system and may require professional assistance to diagnose. For vehicles equipped with advanced systems like Subaru EyeSight®, ensure that calibration is up to date, as improper calibration can lead to malfunctions. By systematically addressing these areas, you can effectively identify and resolve the cruise control issues in your Subaru BRZ.

While a malfunctioning cruise control in your 2013 Subaru BRZ may not seem urgent, it is essential to recognize that ignoring this issue could lead to more significant problems down the line. The cruise control system itself may not pose an immediate safety risk, but it can be a symptom of underlying issues such as a faulty brake pedal switch or a malfunctioning control module. If you notice a check engine light accompanying the cruise control failure, this could indicate that your vehicle is in limp mode or experiencing other critical malfunctions that require prompt attention. By addressing the cruise control issue early, you not only restore a convenient feature but also prevent potential complications that could affect your vehicle's overall performance and safety. Therefore, it is advisable to investigate the root cause of the malfunction and consult a mechanic if necessary, ensuring that your Subaru BRZ remains reliable and safe on the road.
