A: OPERATION
1. HOW TO USE SUBARU SELECT MONI-
TOR
1) Prepare the Subaru Select Monitor kit.
2) Connect the diagnosis cable to Subaru Select
Monitor.
3) Insert the cartridge to Subaru Select Monitor.
4) Connect the Subaru Select Monitor to data link
connector.
(1) Data link connector is located in the lower
portion of the instrument panel (on the driver’s
side).
(2) Connect the diagnosis cable to data link
connector.
CAUTION:
Do not connect the scan tools except for Suba-
ru Select Monitor.
5) Turn the ignition switch to ON (engine OFF), and
the Subaru Select Monitor switch to ON.
6) Using the Subaru Select Monitor, call up DTC
and various data, then record them.
2. READ DIAGNOSTIC TROUBLE CODE
(DTC) FOR ENGINE AND BODY INTEGRAT-
ED UNIT
Refer to “Read Diagnostic Trouble Code” for infor-
mation about how to indicate DTC.
3. COMMUNICATION LINE CHECK
NOTE:
The communication line between ECM and body
integrated unit can be checked in “System Opera-
tion Check Mode”. This is referred to as “Commu-
nication line check”.
1) Connect the Subaru Select Monitor.
2) On the «Main Menu» display screen, select the
{Each System Check} and press the [YES] key.
3) On the «System Selection Menu» display screen,
select the {Engine} and press the [YES] key.
4) Press the [YES] key after the information of en-
gine type is displayed.
