What Does the Check Engine Light Mean?

For your Chevrolet Equinox EV, the illuminated “Check Engine Light” (or sometimes a service propulsion system message) isn’t about a traditional internal combustion engine. Instead, it indicates an issue within your advanced electric propulsion system, high-voltage battery, charging system, or other critical electronic components. This warning light signifies that your vehicle’s onboard diagnostics system has detected a fault that requires immediate attention. Ignoring this light could lead to reduced performance, decreased range, potential system damage, or even a complete breakdown. Don’t take chances with your cutting-edge EV. Trust the certified EV technicians at Joe Bullard Chevrolet in Mobile, AL, who are specifically trained to diagnose and repair issues unique to electric vehicles like your Equinox EV, ensuring its continued reliability and performance.
