What is an OBDII Car Diagnostic Scanner?
OBDII stands for On-Board Diagnostics, generation two. It’s a standardized system that allows external devices, like scanners, to interface with a vehicle’s onboard computer. All cars and light trucks sold in the United States since 1996 are required to be OBDII compliant.
An OBDII car diagnostic scanner plugs into your car’s OBDII port, which is typically located under the dashboard on the driver’s side. Once connected, the scanner can read diagnostic trouble codes (DTCs) stored in your car’s computer. These codes indicate specific issues that your car has detected.
Why Do You Need an OBDII Car Diagnostic Scanner?
Owning an OBDII scanner can save you time, money, and frustration. Here’s why:
- Diagnose Car Problems: Identify the root cause of a check engine light or other warning lights, helping you avoid unnecessary repairs.
- Reset Check Engine Light: After fixing an issue, you can use the scanner to clear the trouble code and turn off the check engine light.
- Monitor Car Performance: Access live data streams from your car’s sensors, like engine RPM, coolant temperature, and oxygen sensor readings.
- Enhanced Car Maintenance: Use the scanner to track maintenance intervals, monitor sensor performance, and get a better understanding of your car’s health.
- Negotiate Repair Costs: Having a basic understanding of the issue before going to a mechanic can help you avoid being overcharged.
