1) Prepare the Subaru Select Monitor kit.
2) Connect the diagnosis cable to Subaru Select
Monitor.
3) Insert the cartridge to Subaru Select Monitor.
eral Description.>
4) Connect the Subaru Select Monitor to data link
connector.
(1) Data link connector is located in the lower
portion of instrument panel (on the driver's
side).
(2) Connect the diagnosis cable to data link
connector.
NOTE:
Do not connect scan tools except for Subaru Select
Monitor.
5) Turn the ignition switch to ON (engine OFF) and
Subaru Select Monitor switch to ON.
6) On the «Main Menu» display screen, select the
{Each System Check} and press the [YES] key.
7) On the «System Selection Menu» display
screen, select the {Transmission} and press the
[YES] key.
8) Press the [YES] key after the information of
transmission type is displayed.
9) On the «Transmission Diagnosis» screen, select
the {DTC Display}, and then press the [YES] key.
NOTE:
