What is an OBD code reader and how is it used?
An OBD (On-Board Diagnostic) scanner-reader is a good device to have for your own car or when shopping for a used vehicle.
When the “Check Engine” light comes on in a vehicle, the vehicle’s computer actually stores and saves the data about the problem that caused the light. The data is stored as a unique code that identifies the problem.
A Check Engine light indicates a problem that, if ignored, can cause one of more of the following issues:
- Serious engine damage
- Poor gas mileage
- Vehicle performance problems
- Expensive repair costs
- Emissions inspection failure
