HOW TO USE Vehicle Diagnostic Interface

Prepare the Vehicle Diagnostic Interface kit.

Connect the diagnosis cable to Vehicle Diagnostic Interface.

Connect the Vehicle Diagnostic Interface to data link connector.

Data link connector located in the lower portion of instrument panel (on driver’s side).
