Diagnostic Trouble Engine Codes are codes that the car’s OBD system uses to notify you about an issue.
Each code corresponds to a fault detected in the car. When the vehicle detects an issue, it will activate the corresponding trouble code.
A vehicle stores the trouble code in it’s memory when it detects a component or system that’s not operating within acceptable limits. The code will help you to identify and fix the issue within the car.
Diagnostic trouble engine codes (or fault codes) are codes that are stored by the on-board computer diagnostic system.
