Step 1: Inspect the Check Engine Light
The first step is to determine why the check engine light is on. Use an OBD-II scanner to read the trouble codes. You can purchase a scanner or visit a local auto parts store that may offer this service for free. Once you retrieve the codes, consult your vehicle’s manual or seek assistance from a professional mechanic to understand the issue.
Step 2: Check the Battery Condition
Next, check the battery voltage to ensure it’s in good condition. If your battery is low, either recharge it or replace it as needed.
Step 3: Test the Key Fob
If the battery is not the issue, try using a spare key fob (if available) to see if the remote start activates. If it does, you’ll know the original key fob battery is the problem.
Step 4: Examine Security Features
Inspect your vehicle’s security system to ensure no faults are locking you out of the remote start function. If necessary, reset the system by following your owner’s manual instructions.
Prevention Tips for Remote Start Issues
After resolving the issue, taking steps to prevent future occurrences can save you time and headaches. Here are some effective tips:
1. Regular Maintenance
Ensure that your vehicle is maintained according to the manufacturer’s schedule. This includes regular oil changes, battery checks, and diagnostics to prevent issues from escalating.
2. Monitor Warning Lights
Always pay attention to dashboard warning lights. If the check engine light comes on, address it immediately instead of waiting for it to potentially impact other systems, such as remote start.
Conclusion
Experiencing issues with your Chevy remote start when the check engine light is illuminated can be a nuisance, but understanding the root causes and troubleshooting effectively can help you resolve the problem. Remember to always keep your vehicle well-maintained and stay informed about any issues indicated by your dashboard lights. Whether it’s a simple dead key fob battery or a more complex engine issue, addressing these items promptly can ensure that you can enjoy the convenience of remote start without hassle.

What causes the check engine light to come on in my Chevy?
The check engine light can illuminate for a variety of reasons, ranging from minor issues to more serious concerns. Common triggers include faulty sensors, such as the oxygen sensor or mass airflow sensor, and issues like a loose gas cap, which can affect fuel efficiency. Each of these scenarios can disrupt the vehicle’s normal operational parameters, prompting the check engine light to engage.
Additionally, more serious problems, such as engine misfires or issues with the exhaust system, can also cause the light to activate. It’s crucial to address the underlying issues as soon as possible, not only because they could affect your vehicle’s performance, but also because they can prevent your remote start feature from functioning properly.
How does the check engine light affect the remote start functionality?
The remote start feature in your Chevy is designed as a safety mechanism to prevent the engine from starting if there’s a fault detected within the vehicle’s systems. When the check engine light is triggered, the vehicle’s onboard diagnostics assume that there is a problem that could affect performance or emissions, which consequently disables the remote start function.
This means that even if the problem is not severe, such as a loose gas cap, your remote start may still be inactive. To restore the functionality of your remote start system, it’s essential to address the issue that triggered the check engine light in the first place.
