What’s The Subaru Cruise Control System?
The Subaru cruise control system helps you keep a steady speed on long drives. It has key parts like the cruise control switch, electronic controls, and speed sensors.
Knowing how it works is key to spotting any problems. In Subaru cars, the cruise control system is easy to use. Just set your speed, and the car will keep it without your foot on the gas.
Knowing how it operates helps you notice if something’s off, like a flashing light. Starting from 2005, Subaru cars have a light that flashes when there’s a problem.
This light is part of a system that checks many car functions. Each Subaru has special codes that tell you about any issues or when it’s time for a check-up.
Common Causes of Subaru Cruise Control Light Flashing
A flashing Subaru cruise control warning light can mean several things are wrong with your car. Knowing what these issues are helps you fix them fast.
Here are some common reasons for this warning light:
- Gas Cap Issue: A loose or broken gas cap can cause the cruise control light to flash. This is because it affects the fuel pressure readings.
- Faulty Speed Sensors: These sensors are key for checking your car’s speed. If they don’t work right, the cruise control might turn off, showing the warning light.
- Electrical Problems: Issues with your car’s electrical system can mess with the cruise control. This includes damaged wiring or blown fuses, which show up as a flashing light.
- Engine Performance Issues: Engine problems often cause the Subaru cruise control warning light to flash. This is because the engine’s diagnostic codes are involved.
Fixing these problems quickly is important to prevent more issues. You might see a check engine light (CEL) on too, which means there’s a problem with the engine.
If both lights are flashing, it usually means the engine is misfiring. But if the CEL is steady and the cruise control light is flashing, it’s a common sign.
Subaru Cruise Control Light Flashing – Quick Fixes
If your Subaru’s cruise control light is flashing, act fast to avoid bigger problems. A few quick checks can solve the issue without needing expensive repairs.

Look out for other warning lights too, not just the cruise control one. The Check Engine Light (CEL) is very important. If you ignore it, you could face expensive repairs and more problems.
Here are some other warning lights to keep an eye on:
- Check Engine Light (CEL) – May signal engine inefficiency and costly repairs if ignored.
- Battery Light – Indicates problems with the electrical system, potentially affecting performance.
- Oxygen Sensor Warning – Can impact both fuel economy and emissions compliance.
- Transmission Light – Signals problems with engine performance and could turn on the CEL.
If you see these lights, it might mean your Subaru’s cruise control problem is part of a bigger issue. Fixing these problems early can save you money and keep your car running well.
Troubleshooting Subaru Cruise Control Problems
Fixing Subaru cruise control issues can save you time and money. Knowing how to find the problem is important.
This guide will help you diagnose and fix issues, including using an OBD-II scanner and checking the electrical system.
Using an OBD-II Scanner
An OBD-II scanner is a great tool for finding cruise control problems. It connects to your car’s diagnostic port and shows fault codes. These codes can tell you why the cruise control light is on.
Getting these codes takes just a few minutes. They help you find and fix specific problems. This makes fixing your Subaru’s cruise control easier.
Checking Vehicle’s Electrical System
Electrical issues can affect your cruise control. It’s important to check the electrical system. Look for any damage, corrosion, or loose connections in the wiring and connectors.
