Will Remote Start Work If Check Engine Light Is On?: Find out the impact of a check engine light on your remote start systemSarah ThompsonSep 06, 2025Table of ContentsTips 1:FAQTable of ContentsTips 1FAQFree Smart Home PlannerAI-Powered smart home design software 2025Home Design for FreeRemote start systems offer great convenience, allowing you to start your vehicle from a distance to warm it up or cool it down before you get inside. But many drivers wonder: will remote start work if the check engine light is on? The answer depends on your vehicle’s system and how it’s programmed for safety and diagnostics.Most modern remote start systems are intentionally designed to disable themselves if the check engine light is illuminated, particularly for emissions or engine-related issues. This is because a check engine light often signals a problem that could affect the engine’s performance or safety. By preventing remote starts, the system helps avoid starting an engine that may be at risk of damage or may not pass emissions checks.That said, not all check engine lights are created equal. Some codes may be considered “minor” (such as a loose gas cap), and some aftermarket remote start systems might still function with those codes present. However, the safest assumption is that a check engine light, especially on newer vehicles with factory-installed remote start, will typically prevent the feature from working until the underlying problem is addressed and the light is cleared.As a designer, it’s essential to always consider the user experience and safety features integrated into any system—automotive or otherwise. Just like a smart home design that automatically shuts off power to a faulty outlet, remote start’s fail-safe with the check engine light ensures that convenience doesn’t override critical maintenance concerns.

Fix the underlying issue, and the remote start should work again once the light is cleared. Always address check engine warnings promptly to ensure vehicle safety and longevity.FAQQ: Can I bypass the system and use remote start with a check engine light on?A: It’s not recommended. Bypassing may endanger your engine or void warranties. It’s best to fix the underlying problem first.Q: What types of check engine lights will disable remote start?A: Most engine/emission-related codes will disable it, but some minor warnings may not. Review your vehicle’s manual for specifics.Q: Does an aftermarket remote start behave differently from a factory system?A: Some aftermarket systems might work with minor codes, but most are designed to mirror the car’s built-in safety features.Q: How can I reset the check engine light to enable remote start?A: Fix the cause of the warning, then use an OBD-II scanner or drive the car until the system resets the light.Q: Is it safe to drive if the check engine light is on but the car runs fine?A: It’s wise to diagnose the issue soon. Sometimes the problem is minor, but it could be an early sign of a more serious concern.Home Design for FreePlease check with customer service before testing new feature.
