What is the Stabilitrak system and what does the check engine light mean?
The Stabilitrak system is a stability control system found on many GM vehicles, including the Chevy Malibu. It helps to keep the vehicle stable and under control by applying the brakes to individual wheels and reducing engine power when necessary.
The check engine light is a warning light that appears on the dashboard of a vehicle when the on-board diagnostic system (OBD-II) detects a problem with the vehicle.
The OBD-II system monitors various systems and components in the vehicle, and the check engine light will come on if it detects a problem that could affect the vehicle’s emissions.
This could be caused by a variety of issues, such as a malfunctioning oxygen sensor, a misfiring engine, or a faulty catalytic converter.
The check engine light is an important warning system because it alerts the driver to a potential issue that could affect the performance and safety of the vehicle.
It is important to have the issue diagnosed and repaired as soon as possible to avoid further problems.
