You can use the Equus 3030 Innova Diagnostic Code Reader to read the codes on an innova 3030.
Take it to Auto Zone and they will read them free.
First you remove the cover from the diagnostic port under the driver's side of the dashboard. Then you plug the datalink cable from your scan tool into the diagnostic port. The scan tool will then show the diagnostic codes. Write them down and read a manual to see what has gone wrong.

To tell you to read the diagnostic codes.
It is the port, where a diagnostic machine can be hooked up. The diagnostic will read codes from your vehicles computer. For instance if your check engine light comes on, you can plug the diagnostic machine into the data port and it will tell you why the check engine light came on so that you can get it fixed.
Reading diagnostic codes is easy. The driver plugs the reader/scanner into the diagnostic port of the vehicle, and the scanner/reader will give a code if there is a problem, and tell them the type of problem.
Diagnostic equipment is needed to read codes on a 92 Golf. DLC is located in dashboard beneath heater controls.
