Having a good OBDII scan tool when troubleshooting a Chevy or GM vehicle is a nice thing to have.
An OBDII scan tool can point to the problem a car or truck is having.
Being able to communicate with the onboard-computer (ECM) will give invaluable data as to what the problem is.
What Is a Chevy OBDII Error Code?
When the on-board computer (ECM) detects an error with the engine or drive-train it turns on the engine light which is also a numerical code.
The code will be a number that points to the problem that has happened.
For example, a P0013 error code would point to an Exhaust Camshaft Position Open on Bank 1.
How To Read or Erase a Chevy OBDII Code
- Plug in an OBDII Scan Tool to the OBDII Port
- Turn on the OBDII Scan Tool
- Select Read or Erase
If you have never used an OBDII scan tool before they are easy to use.
All Chevrolet cars and trucks have an OBDII port to plug into under the driver-side dashboard.
A scan tool simply plugs into the port and is ready to read and erase codes.
Many units have more features such as live data or freeze frame.
