Q
how long to disconnect battery to reset check engine light
I'm a seasoned industrial engineer with a keen interest in machine learning. Here to share insights on latest industry trends.
To reset a car's check engine light by disconnecting the battery, typically, disconnecting the battery terminals for about 15 minutes should suffice. This process effectively clears the vehicle's internal computer system, potentially resetting any stored error codes and turning off the check engine light. However, this approach might not address the underlying issue that triggered the light initially. Modern vehicles, especially those from the mid-2000s onwards, have more sophisticated systems, and merely disconnecting the battery might not reset the light or could lead to other issues, such as loss of radio presets or security codes. It's also crucial to mention that disconnecting the battery will not fix mechanical problems and could even mask serious issues that need professional attention. Always consult your vehicle’s manual or a professional mechanic to understand the implications of disconnecting your battery and to ensure the root cause of the check engine light is properly identified and addressed.
