A brief explanation of the issue
It will make the cruise control light flash until the issue has been corrected. The speed sensor is an essential component that needs immediate fixing when faulty. It is because an issue with this sensor can affect the functioning of the car’s speedometer.
However, if the lights continue flashing, it means that the issue is beyond the fuses, and you will have to check the other components in the cruise control system. To fix the flashing light or check the engine light caused by an engine control unit, you will first check what the code means. You can activate the system by pressing the cruise control button and the vehicle will keep you at the current speed. Cars with advanced cruise control systems use sensors at the front bumper to detect vehicles ahead of them and keep the car at a distance to prevent collision. Driving can be fun, but long-distance driving can be fatiguing as you keep pressing the gas pedal to keep the car going at your desired speed. Thankfully, cars now feature cruise control — a system that lets drivers set a desired speed and relaxes their feet when traveling a long journey.
If you notice the cruise control light flashing, don’t hesitate to take your car to the nearest mechanic. If the switch is failing, it may not properly detect when the brake pedal is pressed, leading to a flashing cruise control light. A faulty battery will cause the engine to misfire, making the check engine light come on and the cruise control system start flashing. It will be shown by the check engine light coming on or the Subaru cruise control light flashing. The most common reason why the cruise control light is flashing on your Subaru is due to an electrical or mechanical problem.

This unit diagnoses problems in your car and relays them to you by sending a code. Let’s be clear here; this does not mean that the PCM must disable the cruise control whenever it detects an issue with the engine or transmission. It will only disable the system if the issue is causing unstable engine performance. This should reset the cruise control light and get your Subaru back on the road. It’s important to pay attention to the Check Engine Light if it illuminates in your vehicle’s instrument cluster.
In this article, you’ll learn what could be causing the flashing light and how to fix it.

When the cruise control light is flashing, it usually means the throttle actuator is in need of service. It can be caused by a malfunctioning throttle position sensor, a bad throttle body, or a faulty electronic throttle control unit. If your Subaru’s cruise control light is flashing, it may be due to a malfunctioning speed sensor. This sensor is responsible for detecting the speed of the vehicle and relaying that information to the cruise control system. If the sensor is not working properly, it can cause the cruise control light to flash. Such problems may include a faulty battery, loose gas cap, damaged fuse, faulty brake pedal, etc.
Fuses safeguard the electrical components in a cruise control system. They act as shields that, when damaged, allow very little or no current to reach the control system. It is because these Subaru models are equipped with an engine control unit.
