Help! My Check Engine Light Is On!

Whether you are using an auto code scanner in a business or for your own personal use, there is one very important thing you need to know—where is the OBD (On-Board Diagnostics) connector?

If you are lucky, you might be able to find the OBD connector (also called a data link connector) without a lot of hunting if you are familiar with the different places where most manufacturers hide them. I use the word "hide" because the manufacturers are not exactly forthcoming about such locations. They want you to come to them for any necessary service.

If you are smart, you can and should have some knowledge of why your check engine light is on before you seek outside assistance. An online or manual search of where that all-important connector to plug in an auto code scanner can be exhausting and not always fruitful.

Where's My OBD Connector?

While there are websites that provide that information upon providing your auto's make, model, and year, they are sometimes difficult to find and wade through.

There are seventeen typical auto computer connector locations. They are:

  1. Behind an ashtray.
  2. Bottom dash, above the hood release.
  3. Dash on right, underneath.
  4. Driver side of dash, above hood release—left-hand side of instrument panel.
  5. Front of center console, driver side.
  6. Front of center console, passenger side.
  7. In front of shifter.
  8. Inside a cavity, lower dash, but next to center console.
  9. Left edge of dash, left of hood release.
  10. Left driver side on dash.
  11. Lower edge of dash, next to transmission tunnel.
  12. Passenger side of the console.
  13. Steering wheel, underneath, center.
  14. Right driver side on dash.
  15. Under driver side of dash, and next to kick panel.
  16. Under the glove box on the passenger side of dash.
  17. Under the passenger dash.

Keep in mind that the exact location can vary, depending upon the year, make, and model. An example would be that if a manufacturer locates the connector under the passenger side of the dash in 1996, that doesn't mean that the next year it wouldn't be under an ashtray or somewhere else. Additionally, some connectors are located upside down, so some attention needs to be paid to this factor when trying to connect.

The key thing to remember is that since 1996, all auto computer code connectors are found somewhere inside the front passenger compartment.

Under Cover?

Manufacturers of all vehicles since 1996 have played around with not only the placement of the computer code connectors but also whether or not they are covered. Some of the manufacturers will do both.

You'll find that if they are covered, it is with either a rubber or plastic cover or even a hinged door. It will be necessary to remove or open this before you can connect your auto code scanner.
