ENGINE (DIAGNOSTIC)
General Description
13) Diagnostics should be conducted by rotating
with simple, easy operations and proceeding to
complicated, difficult operations. The most impor-
tant thing in diagnostics is to understand the cus-
tomer’s complaint, and distinguish between the
three causes.
14) On the model with ABS, when performing driv-
ing test in jacked-up or lifted-up position, some-
times the warning light may be lit, but this is not a
malfunction of the system. The reason for this is the
speed difference between the front and rear
wheels. After diagnosis of engine control system,
perform the ABS memory clearance procedure of
self-diagnosis function.
B: INSPECTION
Before performing diagnostics, check the following
items which might affect engine problems:
1. BATTERY
1) Measure battery voltage and specific gravity of
electrolyte.
Standard voltage: 12 V
Specific gravity: Above 1.260
2) Check the condition of the main and other fuses,
and harnesses and connectors. Also check for
proper grounding.
2. ENGINE GROUND
Make sure the engine ground terminal is properly
connected to the engine.
C: NOTE
1. GENERAL DESCRIPTION
 On-board diagnosis (OBD) system detects and
indicates a fault in various inputs and outputs of the
complex electronic control. Malfunction indicator
light in the combination meter indicates occurrence
of a fault or trouble.
 Further, against such a failure or sensors as may
disable the drive, the fail-safe function is provided
to ensure the minimal driveability.
 The OBD system incorporated with the vehicles
within this engine family complies with Section
1968.1, California Code of Regulations (OBD-II
regulation). The OBD system monitors the compo-
nents and the system malfunction listed in Engine
Section which affects on emissions.
 When the system decides that a malfunction oc-
curs, malfunction indicator light illuminates. At the
same time of the malfunction indicator light illumi-
nation or blinking, the DTC and a freeze frame en-
gine conditions are stored into on-board computer.
 The OBD system stores freeze frame engine
condition data (engine load, engine coolant tem-
perature, fuel trim, engine speed and vehicle
speed, etc.) into on-board computer when it detects
a malfunction first.
 If the OBD system detects the various malfunc-
tions including the fault of fuel trim or misfire, the
OBD system first stores freeze frame engine condi-
tions about the fuel trim or misfire.
 When the malfunction does not occur again for
three consecutive driving cycles, malfunction indi-
cator light is turned off, but DTC remains at on-
board computer.
 The OBD-II system is capable of communication
with a general scan tool (OBD-II general scan tool)
formed by ISO 9141 CARB.
 The OBD-II diagnostics procedure is different
from the usual diagnosis procedure. When trouble-
shooting the OBD-II models, connect Subaru Se-
lect Monitor or the OBD-II general scan tool to the
vehicle.

Inspection Mode
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-

AUTOMATIC TRANSMISSION
Stall Test
5. Stall Test
A: INSPECTION
NOTE:
The stall test is of extreme importance in diagnos-
ing the condition of the automatic transmission and
the engine. It should be conducted to measure the
engine stall speeds in “R” and “2” ranges (when
HOLD switch is ON).
Purposes of the stall test:
 To check the operation of the automatic trans-
mission clutch.
 To check the operation of the torque converter
clutch.
 To check engine performance.
1) Check that the throttle valve opens fully.
2) Check that the engine oil level is correct.
3) Check that the coolant level is correct.
4) Check that the ATF level is correct.
5) Check that the differential gear oil level is cor-
rect.
6) Increase ATF temperature to 70 — 80°C (158 —
176°F) by idling the engine for approximately 30
minutes (with select lever set to “N” or “P”).
7) Place the wheel chocks at the front and rear of
all wheels and engage the parking brake.
8) Shift the manual linkage to ensure it operates
properly, then shift the select lever to the “2” range
and turn the HOLD switch to ON.
9) While forcibly depressing the foot brake pedal,
gradually depress the accelerator pedal until the
engine operates at full throttle.
10) When the engine speed is stabilized, record
that speed quickly and release the accelerator ped-
al.
11) Shift the select lever to “N” range, and cool
down the engine by idling it for more than one
minute.12) If the stall speed in “2” range (with HOLD switch
ON) is higher than specifications, low clutch slip-
ping and “2-4 brake slipping” may occur. To identify
it, conduct the same test as above in “R” range.
13) Perform the stall tests with the select lever in
the “D” range.
NOTE:
 Do not continue the stall test for more than five
seconds at a time (from closed throttle, fully open
throttle to stall speed reading). Failure to follow this
instruction causes the engine oil and ATF to deteri-
orate and the clutch and brake to be adversely af-
fected.
 Be sure to cool down the engine for at least one
minute after each stall test with the select lever set
in the “P” or “N” range and with the idle speed lower
than 1,200 rpm.
 If the stall speed is higher than the specified
range, attempt to finish the stall test in as short a
time as possible, in order to prevent the automatic
transmission from sustaining damage.
