General Scan Tool
ENGINE (DIAGNOSTICS)
8. General Scan Tool
A: OPERATION
1. HOW TO USE GENERAL SCAN TOOL
1) Prepare a scan tool (general scan tool) required
by SAE J1978.
2) Open the cover and connect the general scan
tool to data link connector located in the lower por-
tion of the instrument panel (on the driver’s side).
3) Using the general scan tool, call up DTC and
freeze frame data.
General scan tool functions consist of:
(1) MODE $01: Current powertrain diagnostic
data
(2) MODE $02: Powertrain freeze frame data
(3) MODE $03: Emission-related powertrain
DTC
(4) MODE $04: Clear/Reset emission-related
diagnostic information
Read out the data according to repair procedures.
(For detailed operation procedure, refer to the gen-
eral scan tool instruction manual.)
NOTE:
For details concerning DTC, refer to “List of Diag-
nostic Trouble Code (DTC)”.

2) Connect the diagnosis cable to Subaru Select
Monitor.
3) Insert the cartridge to Subaru Select Monitor.
4) Connect the Subaru Select Monitor to the data
link connector at the lower portion of instrument
panel (on the driver’s side).
CAUTION:
Do not connect any scan tools except Subaru
Select Monitor or 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 DTCs
and data, then record them.

Inspection Mode
ENGINE (DIAGNOSTICS)
1. PREPARATION FOR THE INSPECTION
MODE
1) Check battery voltage is more than 12 V and fuel
remains half [20 to 40 2 (5.3 to 10.6 US gal, 4.4 to
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 roll-
ers.
WARNING:
•Before lifting-up 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 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) After clearing the memory, check for any remain-
ing unresolved trouble data.
2) Idle the engine.
3) Prepare the Subaru Select Monitor kit.
