Engine Control Unit
While this procedure will turn off your Subaru check engine light, it is not recommended because it clears codes that help diagnostics. You may have been told to disconnect the battery negative terminal to turn off the Subaru check engine light for a few minutes. Therefore, if the plug wires malfunction, the engine will supply low power to the Subaru car. The check engine will sense this problem and alert you by turning on its light.

He could not help tinkering with anything he got his hands on from a young age, which led to his remarkable career in the automotive repair industry. The plug wires supply the spark plugs with voltage, which will, in turn, ignite the air and fuel in the combustion chamber, thus making the engine run. 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. There are about 200 codes in these Subaru models, and each one of them indicates a certain level of problem in the car. All you have to do is check if the battery can charge your phone.

It happens when you refuel the car and fail to tighten it correctly. They include a failing fuel injector, wrong fuel mixture, a problem with the check valve, an issue with the oxygen sensor, etc. But if the solenoid valves have malfunctioned due to electric spikes, the only way to resolve the issue is by replacing the damaged components.

If any of the mechanical components go bad, it can disable the system and trigger the blinking light on the dashboard.

Frequently, issues with throttle actuation can also be the culprit behind a Subaru’s flashing cruise control light. 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. Believe it or not, the gas cap plays a crucial role in your vehicle’s overall functionality. The gas cap can affect the performance of the cruise control system. For instance, in Subarus, a loose gas cap can cause the cruise control light to blink as you drive.
Malfunctioning speed sensor
To be precise, the flashing Subaru cruise control light shows there is a mechanical or electrical problem in your car. The cruise control light should be green and steady when you turn on the system. But if the light is flashing, turn off the cruise control until you address the problem. A flashing check engine light is one thing that you should not ignore. While this is not damaging if you drive for a few minutes, it will devastate your engine and catalytic converter if ignored for a long time.
Once the check engine light problem and been fixed, these lights should turn off. Learn what Subaru Check Engine Light (CEL) means, common problems, and how to read engine codes yourself by following the procedures below. Being an avid world traveler, he has spent most of his time analyzing the automotive markets, latest technology, and local favorites to enhance his knowledge base.
A check engine light will flash rapidly, but no codes will be stored. A flashing Cruise Control or Vehicle Dynamics Control light sometimes accompanies the Subaru check engine light. It simply means that they are disabled due to the engine problem.

In most cases, this is caused by a blown fuse in the engine compartment fuse box. Read the fault codes to find out why the check engine light stays. When a Subaru On-Board Diagnostic (OBD) detects a problem with the engine, emission system, or transmission, it triggers the check engine light. The OBD system then stores a fault code (also known as Diagnostic Trouble Code or DTC) in the memory, which you can retrieve with an OBD-II scanner, like the YOUCANIC FUll System Scanner.
Replacing the switch when necessary can help ensure the cruise control system is working correctly and the flashing light isn’t a cause for alarm. In this article, you’ll learn what could be causing the flashing light and how to fix it. We’ll also discuss some other issues related to cruise control, so you can be better prepared if something similar happens in the future. To determine the root cause of the malfunction, you need a mechanic to diagnose the vehicle. The mechanic will inspect all cruise control components and may plug in a scan tool to pull out all the error codes in the vehicle. You can activate the system by pressing the cruise control button and the vehicle will keep you at the current speed.
Let’s have an in-depth look to see how these issues could cause cruise control light flashing on Subaru Outback and other Subaru models. If you notice the cruise control light flashing and check engine light is on, check the vehicle speed sensor. A bad speed sensor triggers the check engine light and disables the cruise control system. So, if it is the root cause, the only solution is to replace it with a new one. Apart from a faulty brake pedal switch, malfunctioning mechanical components can also be responsible for your Subaru’s cruise control light flashing. This includes a problem with the throttle control motor, the cruise control switch, the brake light switch, the cruise control actuator, and the ECU.
We are an automotive mechanic blog that helps mechanics and car users to find the most recent and accurate technical and repair information for their cars. We created this blog site in 2018 to enable us to share our knowledge with other automotive mechanics and car owners. 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.
They will cause the check engine to come on when faulty, making the cruise control light flash. This code is usually accompanied by a check engine light or flashing light from the cruise control system. It is important to check why your Subaru’s cruise control light is flashing in order to avoid any potential issues. Lastly, an issue with the traction control system can cause the cruise control light to flash. The traction control system is closely linked to the cruise control system, and if there is a problem with the traction control system, it can trigger the cruise control light to flash. If the switch goes bad, the brake lights won’t know when you step on the brake pedal.
The most common reason why the cruise control light is flashing on your Subaru is due to an electrical or mechanical problem. Remember, when the light is flashing, the cruise control system is disabled, so don’t try to turn it on because it won’t work. Also, remember that your Subaru check engine light will return if the problem hasn’t been fixed. You will not pass a state emission test if you recently disconnected the battery or cleared the codes with an OBD2 scanner.
If your phone’s battery percentage does not go up, you have a bad battery that you should replace. Your car’s engine has solenoid valves that control the flow of fluids such as oil. If the code indicates that your Subaru has a severe problem, then tow it to the mechanic, who will fix the issue. If the code implies a less severe issue that you can quickly fix, then do so and proceed to delete the code using an OBDII reader. Driving continuously without stopping to rest can drain your energy and even harm your car.
It is because these Subaru models are equipped with an engine control unit. This unit diagnoses problems in your car and relays them to you by sending a code. This should reset the cruise control light and get your Subaru back on the road. In any of these cases, the throttle needs to be repaired or replaced. Proper troubleshooting is essential to identify the source of the issue and to ensure a proper repair.
