Subaru Forester Check Engine Light with Flashing Cruise Control: A Comprehensive Guide
As an avid outdoor enthusiast, my Subaru Forester has been my trusty companion on countless adventures. However, during a recent road trip, I encountered a puzzling issue – the check engine light illuminated, accompanied by a flashing cruise control indicator. Determined to resolve the problem, I embarked on a journey of research and troubleshooting, which I am eager to share with fellow Subaru owners.
My initial instinct was to consult the vehicle’s owner’s manual. It revealed that the check engine light, when accompanied by a flashing cruise control indicator, could signal various issues, ranging from minor sensor malfunctions to more severe mechanical problems. This realization heightened my concern and prompted me to delve deeper into the potential causes and solutions.
Identifying the Underlying Issue
The check engine light is a vital component of a vehicle’s diagnostic system, designed to alert drivers to any potential issues within the engine or emission control system. When illuminated, it indicates that the vehicle’s computer (ECU) has detected a fault that may affect performance or emissions. The flashing cruise control indicator, on the other hand, is specifically related to the vehicle’s cruise control system, suggesting a potential issue with its functionality or operation.
The combination of these two indicators can arise due to several factors. Common causes include:
- Faulty or malfunctioning cruise control switch
- Electrical issues within the cruise control system
- Sensor problems involving the throttle position, brake pedal, or steering wheel angle
- Mechanical issues with the throttle body or cruise control actuator
Troubleshooting and Repair
To address this issue effectively, it is crucial to identify the underlying cause accurately. Basic troubleshooting steps include:
- Inspecting the cruise control switch for any damage or malfunction
- Checking the electrical connections within the cruise control system for any loose or damaged wires
- Cleaning the throttle position sensor or any other relevant sensors
- Testing the throttle body or cruise control actuator for proper operation
Depending on the severity of the issue, these troubleshooting steps may resolve the problem or provide valuable insights into the necessary repairs. More complex issues, such as mechanical problems with the throttle body or cruise control actuator, may require professional diagnosis and repair at a Subaru dealership or qualified mechanic.
Expert Advice and Tips
Based on my research and experience, I have compiled a few valuable tips and expert advice for Subaru Forester owners:
- Regularly inspect the cruise control switch and check for any signs of damage or malfunction
- Keep the vehicle’s electrical system well-maintained, ensuring that all connections are secure and free of corrosion
- Clean or replace the throttle position sensor if any performance issues or warning lights arise
- Avoid using the cruise control system if any issues are suspected, as it could potentially exacerbate the problem
- If the check engine light and flashing cruise control indicator persist, seek professional diagnosis and repair promptly
Frequently Asked Questions

- Q: Can I reset the check engine light and flashing cruise control indicator myself?
A: While some generic OBD-II scanners can reset the check engine light, it is not recommended to attempt this with the flashing cruise control indicator. The underlying issue should be diagnosed and resolved first.
- Q: Why does my cruise control keep turning off and on?
A: This could be due to a faulty cruise control switch, electrical issues, or a sensor malfunction. It is advisable to have it inspected by a mechanic.
