1. HOW TO USE SUBARU SELECT MONI-
TOR
1) Prepare the Subaru Select Monitor kit. EN(H4DOTC 2.5)-7, PREPARATION TOOL, Gen-
eral Description.>
2) Connect the diagnosis cable to Subaru Select
Monitor.
3) Insert the cartridge to Subaru Select Monitor. to EN(H4DOTC 2.5)-7, PREPARATION TOOL,
General Description.>
4) Connect the Subaru Select Monitor to data link
connector.
(1) Data link connector located in the lower por-
tion 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 and OBD-II general scan tool.5) Turn the ignition switch to ON (engine OFF) and
Subaru Select Monitor switch to ON.
6) Using the Subaru Select Monitor, call up DTC
and data, then record them.

1. PREPARATION FOR THE INSPECTION
MODE
1) Check battery voltage is more than 12 V and fuel
remains half [20 — 402 (5.3 — 10.6 US gal, 4.4 —
8.8 Imp gal)].
2) Lift-up the vehicle using a garage jack and place
it on rigid racks or drive the vehicle onto free rollers.
WARNING:
 Before raising the vehicle, ensure parking
brakes are applied.
 Do not use a pantograph jack in place of a rig-
id rack.
 Secure a rope or wire to the front or rear tow-
ing hooks to prevent the lateral runout of front
wheels.
 Do not abruptly depress/release clutch pedal
or accelerator pedal during works even when
the engine is operating at low speeds since this
may cause vehicle to jump off free rollers.
 In order to prevent the vehicle from slipping
due to vibration, do not place any wooden
blocks or similar items between the rigid racks
and the vehicle.
 Since the rear wheels will also rotate, do not
place anything near them. Also, make sure that
nobody goes in front of the vehicle.
2. SUBARU SELECT MONITOR
1) Idle the engine.
2) Prepare the Subaru Select Monitor kit. EN(H4DOTC 2.5)-7, PREPARATION TOOL, Gen-
eral Description.>
