What Does the Dodge Charger Check Engine Light Do?
The Charger’s malfunction indicator lamp (MIL) switches on when the PCM detects a fault that affects emissions or drivability. It stores diagnostic trouble codes, guides technicians to the subsystem in question, and flashes during severe misfires. Treat the light as an early warning to investigate and repair the problem quickly.
- Steady light: Indicates stored codes—scan and schedule diagnostics soon.
- Flashing light: Signals a severe misfire—reduce throttle immediately to protect the catalytic converters.
- After repair: Clear the MIL with a scan tool and complete a drive cycle so readiness monitors reset.
