Scan Tool Testing and Procedures

SCAN TOOL DIAGNOSIS

The scan tool is needed for operational testing of electronic components such as the PCM, electronic accelerator pedal potentiometer, and engine sensors.

The scan tool is connected to the vehicle electrical system through the diagnostic/data link connector. The connector is a black 16-way connector. It is located under the instrument panel near the steering column.
