2. General Description
A: CAUTION
CAUTION:
•The airbag system wiring harnesses and con-
nectors are yellow. Do not use electrical test
equipment on these circuits.
•Be careful not to damage the airbag system
wiring harness.
•While diagnostic items are being checked, do
not operate radios, portable telephones, etc.
which emit electromagnetic waves near or in-
side the vehicle.
•When turning the ignition switch to ON or
OFF while diagnostic items are being checked,
do not allow keys with different ID codes close
to the ignition switch. If the ignition key is in a
key holder, remove it from the holder before
carrying out diagnosis.
•When repeatedly turning the ignition switch
to ON or OFF while diagnostic items are being
checked, it should be switched in cycles of
“ON” for at least 5 seconds → “O F F ” fo r a t le a s t
8 seconds.
•If the engine fails to start with a registered ig-
nition key, detach the ignition key from ignition
switch and wait for approx. 1 second until secu-
rity indicator light begins to flash. And then
start the engine again.
•Before checking the diagnostic items, obtain
all keys for the vehicle to be checked pos-
sessed by owner.
•Do not install or register a body integrated
unit of another registered vehicle to diagnose
failures or inspect functions.

Step Check Yes No
1CHECK THE VDCCM&H/U POWER SUPPLY
CIRCUIT.
1) Turn the ignition switch to OFF.
2) Disconnect the VDCCM&H/U connector.
3) Turn the ignition switch to ON.
4) Measure the voltage between VDCCM&H/
U connector terminals.
Connector & terminal
(B310) No. 1 (+) — (B310) No. 43 (–):
Is the voltage 10 — 15 V? Go to step 2.Check the genera-
tor, batter y and
VDCCM&H/U
power supply cir-
cuit.
2CHECK OUTPUT OF ABS WHEEL SPEED
SENSOR USING SUBARU SELECT MONI-
TOR.
1) Select {Current Data Display & Save} in
Subaru Select Monitor.
2) Read the ABS wheel speed sensor output
corresponding to the faulty wheel in Subaru
Select Monitor data display mode.
Does the speed indicated on
the display change in response
to the speedometer reading
during acceleration/decelera-
tion when the steering wheel is
in the straight-ahead position?
Go to step 3.Go to step 8.
3CHECK POOR CONTACT IN CONNECTOR.
Tu r n t h e i g n i t i o n s w i t c h t o O F F.
Is there poor contact in con-
nectors between VDCCM&H/U
and ABS wheel speed sensor?
Repair the con-
nector.
Go to step 4.
4CHECK CAUSE OF SIGNAL NOISE.
Make sure the radio wave devices and electric
components are installed correctly.
Are the radio wave devices and
electric components installed
correctly?

Go to step 7.
7CHECK OTHER DTC DETECTION.Is any other DTC displayed? Perform the diag-
nosis according to
DTC.
It results from a
temporary noise
interference.
8CHECK INSTALLATION OF ABS WHEEL
SPEED SENSOR.
Is the ABS wheel speed sen-
sor installation bolt tightened
7.5 N·m (0.76 kgf-m, 5.5 ft-lb)?
Go to step 9.Tighten the ABS
wheel speed sen-
sor installation
bolts.
9CHECK ABS WHEEL SPEED SENSOR SIG-
NAL.
1) Install the ABS wheel speed sensor.
2) Prepare an oscilloscope.
3) Check the ABS wheel speed sensor. to VDC-22, ABS WHEEL SPEED SENSOR,
INSPECTION, Front ABS Wheel Speed Sen-
sor.>
Does the oscilloscope indicate
the waveform pattern like
shown in the figure when the
tire is slowly turned? Does the
oscilloscope indication repeat
the waveform pattern like
shown in the figure when the
tire is slowly turned in equal
speed for more one rotation?
Go to step 11.Go to step 10.

Are there foreign matter,
breakage or damage at the tip
of ABS wheel speed sensor or

throughly. Also
replace the ABS
wheel speed sen-
sor or magnetic
encoder as a unit
with hub unit bear-
ing if it is broken or
damaged.

General Description
ENGINE (DIAGNOSTICS)
3. General Description
A: CAUTION
1) Airbag system wiring harness is routed near the
ECM, main relay and fuel pump relay.
CAUTION:
•All airbag system wiring harnesses and con-
nectors are colored yellow. Do not use electri-
cal test equipment on these circuits.
•Be careful not to damage the airbag system
wiring harness when servicing the ECM, TCM,
main relay and fuel pump relay.
2) Never connect the battery in reverse polarity.
•The ECM will be destroyed instantly.
•The fuel injector and other parts will be dam-
aged.
3) Do not disconnect the battery terminals while the
engine is running.
A large counter electromotive force will be generat-
ed in the generator, and this voltage may damage
electronic parts such as ECM etc.
4) Before disconnecting the connectors of each
sensor and ECM, be sure to turn the ignition switch
to OFF. Perform the clear memory mode after con-
necting the connectors.
5) Poor contact has been identified as a primary
cause of this problem. Measure the voltage or re-
sistance of individual sensor or all electrical control
modules using a tapered pin with a diameter of less
than 0.64 mm (0.025 in). Do not insert the pin more
than 5 mm (0.20 in) into the part.
6) Remove the ECM from the located position after
disconnecting two cables on battery.
Otherwise, the ECM may be damaged.
CAUTION:
When replacing the ECM, be careful not to use
the wrong spec. ECM to avoid any damage on
the fuel injection system.
7) Connectors of each sensor in the engine com-
partment and the harness connectors on the en-
gine side and body side are all designed to be
waterproof. Even if the connectors are waterproof,
take care not to allow water to get into them when
washing the vehicle, or when servicing the vehicle
in rainy weather.
8) Use ECM mounting stud bolts as the grounding
point to chassis when measuring voltage and resis-
tance in the passenger compartment.
9) Use the engine ground terminal or engine as-
sembly as the grounding point to chassis when
measuring the voltage and resistance in engine
compartment.
10) Every MFI-related part is a precision part. Do
not drop them.
11) Observe the following cautions when installing
a radio in MFI equipped models.
CAUTION:
•The antenna must be kept as far apart as pos-
sible from control unit. (The ECM is located un-
der the steering column, inside of the
instrument panel lower trim panel.)
•The antenna feeder must be placed as far apart
as possible from the ECM and MFI harness.
•Carefully adjust the antenna for correct
matching.
•When mounting a large power type radio, pay
special attention to the three items mentioned
above.
•Incorrect installation of the radio may affect
the operation of ECM.
12) Release the pressure in the fuel system before
disconnecting the fuel hose. If engine starts during
this operation, run it until it stops.
13) For the model with ABS, the ABS warning light
may illuminate when performing driving test with
jacked-up or lifted-up condition, but this is not a
system malfunction. The reason for this is the
speed difference between the front and rear
wheels. After diagnosis of engine control system,
perform the ABS memory clear procedure of self-
diagnosis function.
B: INSPECTION
Before performing diagnostics, check the following
item which might affect engine problems.
1. BATTERY
1) Measure the 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 engine.

Basic Diagnostic Procedure
WIRING SYSTEM
•The wire color code, which consists of two letters
(or three letters including Br or Lg), indicates the
standard color (base color of the wire covering) by
its first letter and the stripe marking by its second
letter.
•The table lists the nominal sectional areas and
allowable currents of the wires.
CAUTION:
When replacing or repairing a wire, be sure to
use the same size and type of the wire which
was originally used.
NOTE:
•The allowable current in the table indicates the
tolerable amperage of each wire at an ambient
temperature of 40°C (104°F).
•The allowable current changes with ambient
temperature. Also, it changes if a bundle of more
than two wires is used.
•Each unit is either directly grounded to the body
or indirectly grounds through a harness ground ter-
minal. Different symbols are used in the wiring dia-
gram to identify the two grounding systems.
•The ground points shown in the wiring diagram
refer to the following:
NOTE:
All wiring harnesses are provided with a ground
point which should be securely connected.
