Will Remote Start Work with Engine Light On?: 1 Minute to Understand the Impact of Engine Light on Your Remote Start

Wondering if your remote start will work while that pesky engine light is on? You’re not alone! Many vehicle owners find themselves in a similar situation, and it raises some important questions about car safety and functionality. Let's dive into what that engine light means and how it affects your remote start system.

The Relationship Between Engine Light and Remote Start

Before answering the critical question, it's vital to understand the purpose of the engine light. Essentially, your vehicle’s engine light alerts you to potential issues with the engine or emission control systems. When the light is illuminated, it indicates that there may be a problem requiring attention.

Now, when it comes to remote start systems, many modern cars are equipped with safety features that will prevent the remote start from activating if they detect an issue—including a lit engine light. This is a protective measure aimed at preventing further damage to your engine.

Common Reasons for Engine Light Activation

The engine light can be triggered by a myriad of issues, ranging from minor to significant. Some common causes include:

Ignoring the engine light could lead to more severe problems, including increased fuel consumption and extensive engine damage, which can incur significant repair costs.

What to Do When Your Engine Light is On

If you notice that your engine light is illuminated, here are some steps you should take:

Check the gas cap—ensure it’s tight and properly sealed.

Use an OBD-II scanner to read the error codes from your car’s computer, if available.

Troubleshoot common issues linked to the codes obtained.

Schedule an inspection with a professional mechanic to diagnose and resolve the problem.

When Remote Start is Disabled

In many cases, if the engine light is on, the vehicle's computer has likely disabled the remote start functionality. This ensures that the engine isn't operating under potentially harmful conditions. If you attempt to start your vehicle remotely and it fails, it's likely due to this built-in safety feature.

Conclusion

In summary, the presence of a lit engine light typically means that your remote start will not work. It’s crucial to address the issues indicated by the engine light as soon as possible to ensure your vehicle runs safely and efficiently. A proactive approach will not only enhance your driving experience but also extend the life of your vehicle.
