These codes provide insights into potential problems, ranging from minor sensor malfunctions to more significant engine issues.

Connecting the KB30 to Your Vehicle

Locating your vehicle’s OBD2 port is the first step. This port is usually located under the dashboard on the driver’s side. Once located, simply plug the KB30 connector into the port. Ensure the connection is secure. Next, turn the ignition key to the “on” position without starting the engine. This powers up the KB30 and allows it to communicate with your vehicle’s computer.
