The Purpose Of Automotive Scan Tool And Code Readers
Vehicle Diagnostic Scanner Automotive Scan tools and code readers are electronic devices that are used to read information from a vehicle's computer and display it for maintenance diagnostics. Most modern cars and trucks include an Electronic Control Module (ECM) that gauges the performance of that vehicle to ensure proper functioning. When something seems to be wrong, the ECM sends a signal to the Onboard Diagnostic (OBD) system, which then alerts the driver of a problem. This warning usually comes in the form of a check engine light or similar notification. Illumination of the check engine light, however, only indicates that something is wrong with the vehicle, it does not relay any specific information about the issue. The OBD system is able to recognize the general location of the problem that has occurred and can relay information about general vehicle performance. All of this data can be retrieved and read through the use of devices such as scan tools and code readers, whi
