An on-board diagnostic connector is used
by the service station to link the vehicle to
the shop diagnostics system. It allows the
accurate identification of system malfunc-
tions through the readout of diagnostic trou-
ble codes. It is located in the front left area
of the footwell next to the parking brake.
i Some states may by law require you to visit
a workshop immediately as soon as the engine
