What is an Engine Code Checker?

An engine code checker, also known as an OBD II scanner, is a device that can be used to read and clear diagnostic trouble codes (DTCs) from a vehicle’s engine control unit (ECU).

An engine code checker can help you to identify the source of a problem by providing you with the specific DTC that has been stored.

There are a few different ways to clear a DTC with an engine code checker. The most common method is to use the erase or clear function on the scanner. Some scanners also allow you to clear DTCs by disconnecting the battery for a short period of time.

When Should You Clear a DTC?
