D: DTC 27 ODS COMMUNICATION ERROR
Perform the diagnosis following diagnostic procedure for airbag system.
3 CHECK THE AIRBAG HARNESS.
1) Turn the ignition switch to OFF, disconnect
the battery ground cable, and wait more than
20 seconds.
2) Disconnect the test harness AC from the
belt tension sensor connector (AB56).
3) Connect the test harness AD (1AD) to the
connector (AB56).
4) Disconnect the airbag harness connector
(AB61), and connect the connector (1AB) in
test harness AB.
5) Measure the resistance between test har-
ness terminals.
Connector & terminal
(2AB) No. 5 — (2AD) No. 1:
(2AB) No. 4 — (2AD) No. 3:
(2AB) No. 6 — (2AD) No. 2:
Is the resistance less than 10
Ω?
Go to step 4.Replace the airbag
harness with chas-
sis harness.
4 CHECK THE AIRBAG HARNESS.
Measure the resistance between test harness
terminals, and between test harness terminal
and chassis ground.
Connector & terminal
(2AB) No. 4 — (2AD) No. 1:
(2AB) No. 4 — (2AD) No. 2:
(2AB) No. 4 — chassis ground:
(2AB) No. 5 — (2AD) No. 2:
(2AB) No. 5 — chassis ground:
Is the resistance more than 1
MΩ?
Go to step 5.Replace the airbag
harness with chas-
sis harness.
5 CHECK THE AIRBAG HARNESS.
1) Connect the battery ground terminal and
turn the ignition switch to ON.
2) Measure the voltage between test harness
and chassis ground.
Connector & terminal
(2AD) No. 1 — chassis ground:
(2AD) No. 3 — chassis ground:
Is the voltage less than 1 V? Replace the airbag
harness with chas-
sis harness.
Check the seat
harness, and if any
fault is found,
replace the seat
harness. If no fault
is found in the seat
harness, replace
the seat cushion
frame assembly.

Basic Diagnostic Procedure
BRAKE VACUUM CONTROL (BVC) (DIAGNOSTICS)
1. Basic Diagnostic Procedure
A: PROCEDURE
CAUTION:
•Subaru Select Monitor is required for reading DTC, reading the current data and clearing the mem-
ory.
•Remove foreign matter (dust, water, oil, etc.) from the engine control module (ECM) connector
when removing or installing.
NOTE:
•To check the harness for broken wires or short circuits, shake problem spot or connector.
•Refer to “Check List for Interview”.
Step Check Yes No
1CHECK PRE-INSPECTION.
1) Ask the customer when and how the trou-
ble occurred using interview check list.
2) Check the error display. (Odo/trip meter)
Is “Er-bb” displayed on the
screen?
Go to step 3.Go to step 2.
2BASIC INSPECTION
Check the components which might affect the
brake vacuum control.

Steering Gearbox
POWER ASSISTED SYSTEM (POWER STEERING)
1) Lift-up the vehicle.
2) If a fluid leak is found, clean the fluid completely
from the suspect area, and turn the steering wheel
approx. 30 to 40 times to the left and right from lock
to lock, with the engine running, and check again
for leaks immediately, and also after a few hours
have passed.
3) Cause and solution for oil leakage from “a”
The oil seal is damaged. Replace the valve assem-
bly with a new one.
4) Cause and solution for oil leakage from “b”.
The torsion bar O–ring is damaged. Replace the
valve assembly with a new one.
5) Cause and solution for oil leakage from “c”.
The oil seal is damaged. Replace the valve assem-
bly or oil seal with a new one.
6) Cause and solution for oil leakage from “d”.
The pipe is damaged. Replace the faulty pipe or O-
ring.
7) Cause and solution for oil leakage from “g”.
The hose is damaged. Replace the hose with a
new one.
8) If leak is other than a, b, c, d or g, or if oil is leak-
ing from gearbox, move the right and left boots to-
ward tie-rod end side, respectively, with the
gearbox mounted to the vehicle, and remove fluid
from surrounding portions. Then, turn the steering
wheel from lock to lock about thirty to forty times
with the engine running, and make comparison of
the leaked portion immediately after and several
hours after this operation.
(1) Leakage from “e”
The cylinder seal is damaged. Replace the rack
bushing with a new one.
(2) Leakage from “f”
There are two possible causes. Perform the fol-
lowing step first. Remove the pipe assembly B
from the valve housing, and close the circuit us-
ing ST.
ST 926420000 PLUG
Turn the steering wheel from lock to lock ap-
prox. 30 to 40 times with the engine running,
then inspect the leaked portion immediately af-
ter and several hours after this operation.
•If leakage from “f” is noted again:
The oil seal of pinion & valve assembly is dam-
aged. Replace the pinion & valve assembly with a
new one. Or replace the oil seal and the parts that
are damaged during disassembly with new ones.
•If oil stops leaking from “f”:
The oil seal of rack housing is damaged. Replace
the oil seal and parts that are damaged during dis-
assembly with new ones.
F: ADJUSTMENT
1) Adjust the front toe.
Standard of front toe:
IN 3 — OUT 3 mm (IN 0.12 — OUT 0.12 in)
2) Adjust the steering angle of the wheels.
Specification of steering angle:
3) If the steering wheel spokes are not horizontal
when wheels are set in the straight ahead position,
or error is more than 5° on the periphery of the
steering wheel, correctly re-install the steering
wheel.
4) If the steering wheel spokes are not horizontal
with vehicle set in the straight ahead position after
this adjustment, correct it by turning the right and
left tie–rods in the opposite direction from each oth-
er by the same angle.
