Common Causes
The blinking cruise control light in a Subaru can be a cause for concern. Understanding the common causes can help you diagnose and fix the issue. Below, we explore some frequent reasons behind this problem.
Sensor Issues
One of the most common causes is sensor issues. These sensors are essential for cruise control functionality. They monitor speed, braking, and other factors. When they malfunction, the cruise control light may blink.
Common sensor issues include:
- Faulty speed sensor
- Malfunctioning brake sensor
- Throttle position sensor problems
A faulty speed sensor can’t read your car’s speed accurately. This causes the cruise control system to fail. Similarly, a problematic brake sensor may send incorrect signals. This can disable the cruise control. Lastly, throttle position sensor issues can lead to inconsistent speed control.
Wiring Problems
Wiring problems are another frequent cause. The cruise control system relies on a network of wires. These wires connect various components and sensors. Any damage or disconnection can lead to a blinking cruise control light.
Common wiring problems include:
- Loose connections
- Frayed or damaged wires
- Corroded connectors
Loose connections can disrupt the signal flow. This affects the cruise control system. Frayed or damaged wires can cause short circuits. This can also lead to blinking lights. Corroded connectors may prevent proper electrical contact. This can result in intermittent cruise control function.
Here is a simple table summarizing common causes:
| Cause | Details |
|---|---|
| Sensor Issues | Faulty speed, brake, or throttle position sensors |
| Wiring Problems | Loose connections, frayed wires, or corroded connectors |
Understanding these common causes can help you address the blinking cruise control light in your Subaru. Proper diagnosis and repair can ensure your cruise control functions smoothly.

Safety Precautions
Seeing a blinking cruise control light on your Subaru can be alarming. It’s essential to know the safety precautions to take to protect yourself and your vehicle. Here are some steps you should consider.
Check Engine Light
The first step is to check the engine light. When the cruise control light blinks, it often indicates an engine issue. This can be minor or more serious. Follow these steps:
- Look at your dashboard for the check engine light.
- If it is on, find a safe place to pull over.
- Turn off the engine and wait a few minutes.
- Restart the car and see if the light remains on.
If the check engine light stays on, drive to the nearest auto repair shop. Do not ignore this warning.
Driving Speed
Be mindful of your driving speed if the cruise control light is blinking. This can affect your vehicle’s performance. Follow these tips:
- Reduce your speed gradually.
- Avoid sudden acceleration or deceleration.
- Maintain a steady speed to prevent further issues.
- Stay in the right lane to allow faster vehicles to pass.
Driving at a moderate speed can help you control your vehicle better.
These safety precautions can help you manage the situation effectively. Pay attention to any signs your Subaru gives you. Keeping yourself and others safe should be your top priority.
Basic Troubleshooting
Experiencing a blinking cruise control light in your Subaru can be concerning. Before rushing to the mechanic, try some basic troubleshooting steps. These steps may resolve the issue without needing professional help. This section covers two essential checks: restarting the car and checking the brake lights.
Restart The Car
A simple restart can sometimes fix many car issues. Turn off your Subaru completely. Wait for a minute. Then, start the engine again. This action can reset the car’s systems. Check if the cruise control light stops blinking after the restart. If the light persists, move on to the next step.
Check Brake Lights
The brake lights play a crucial role in cruise control functions. A faulty brake light can trigger the blinking cruise control light. Get out of the car and check if all brake lights are working. Ask someone to press the brake pedal while you observe the lights. If any light is out, replace the bulb. This might resolve the blinking light issue.

Advanced Diagnostics
Understanding the blinking cruise control light in your Subaru requires advanced diagnostics. This light may indicate underlying issues. Advanced diagnostics help pinpoint the exact problem. Below, we discuss two essential tools for this process.
Obd-ii Scanner
An OBD-II scanner is a crucial tool for car diagnostics. It reads the data from your Subaru’s onboard computer. Plug the scanner into your vehicle’s OBD-II port. The scanner will then communicate with your car’s systems. This tool helps identify the source of the blinking cruise control light.
Using an OBD-II scanner is simple. Turn on the ignition but do not start the engine. The scanner will display codes that need further analysis. Each code relates to a specific issue within your vehicle.
Error Codes
Error codes are essential for diagnosing problems in your Subaru. These codes help identify faults in various systems. The OBD-II scanner will display error codes once connected. Each code corresponds to a different issue. For instance, a P0420 code may indicate a catalytic converter problem.
Understanding these codes is vital. It helps you determine the next steps. Some issues may require professional repair. Others might be simple fixes you can handle yourself. Always refer to your vehicle’s manual for guidance.
Diy Fixes
Experiencing a blinking cruise control light in your Subaru can be frustrating. Fortunately, you can resolve some issues yourself. These DIY fixes can save you time and money. Let’s explore some common solutions.
Replace Fuse
A blown fuse can cause the cruise control light to blink. Locate the fuse box in your Subaru. Refer to the owner’s manual to find the specific fuse for the cruise control system. Remove the faulty fuse using a fuse puller or needle-nose pliers. Replace it with a new fuse of the same amperage. Ensure the new fuse is seated properly. This simple fix might solve the issue.
Reconnect Sensors
Loose or disconnected sensors can trigger the blinking light. Check the sensors near the brake pedal and throttle. Ensure all connections are secure. Look for any signs of damage or wear. Clean the connectors if necessary. Reconnect any loose sensors firmly. Test the cruise control system after reconnecting. This can restore normal operation.
