Monitor to ON.
4) Read the input signal of the key warning
switch from the Subaru Select Monitor.
Select Monitor.>
Is “ON” displayed? Go to step 2.Go to step 4.
2CHECK INPUT SIGNAL OF BODY INTE-
GRATED UNIT USING SUBARU SELECT
MONITOR.
1) Shift the select lever to “P” range.
2) Read the input signal of “P” range switch
from Subaru Select Monitor.
Select Monitor.>
Is “ON” displayed? Go to step 3.Go to step 8.
3CHECK DTC OF BODY INTEGRATED UNIT.
Check DTC of the body integrated unit.
Diagnostic Trouble Code (DTC).>
Is DTC (B0105) displayed? Repair or replace it
according to the
DTC.
Check the body
integrated unit.
4CHECK HARNESS BETWEEN BATTERY
AND KEY WARNING SWITCH.
1) Disconnect the connector of key warning
switch.
2) Measure the voltage of harness between
key warning switch and chassis ground.
Connector & terminal
(B350) No. 3 (+) — Chassis ground (–):
Is the voltage 9 — 16 V? Go to step 5.Repair the open or
short circuit of har-
ness between bat-
tery and key
warning switch.
5 CHECK KEY WARNING SWITCH.
Measure the resistance between connector
terminals of key warning switch.
Te r m i n a l s
No. 3 — No. 4:
Is the resistance more than 1
MΩ?
Replace the key
warning switch.
Go to step 6.
6 CHECK KEY WARNING SWITCH.
1) Remove the key.
2) Measure the resistance between connector
terminals of key warning switch.
Te r m i n a l s
No. 3 — No. 4:
Is the resistance more than 1
MΩ?
Go to step 7.Replace the key
warning switch.
7CHECK HARNESS BETWEEN AT SHIFT
LOCK CONTROL MODULE AND KEY
WARNING SWITCH.
1) Disconnect the connector of body inte-
grated unit.
2) Measure the voltage between body inte-
grated unit and chassis ground.
Connector & terminal
(B281) No. 7 (+) — Chassis ground (–):
Is the voltage more than 9 V? Go to step 8.Repair the open
circuit of harness
between body inte-
grated unit and key
warning switch.
8CHECK HARNESS BETWEEN “P” RANGE
SWITCH AND CHASSIS GROUND.
Measure the resistance of harness between
“P” range switch and chassis ground.
Connector & terminal
(B116) No. 1 — Chassis ground:
Is the resistance less than 1
Ω?
Go to step 9.Repair the short
circuit of harness
between “P” range
switch and body
integrated unit.

Working Precautions
WIRING SYSTEM
2. Working Precautions
A: PRECAUTIONS WHEN WORKING
WITH THE PARTS MOUNTED ON
THE VEHICLE
1) When working under a vehicle which is jacked-
up, always be sure to use rigid rack.
2) The parking brake must always be applied dur-
ing working. Also, in automatic transmission vehi-
cles, keep the select lever set to the P (Parking)
range.
3) Be sure the workshop is properly ventilated
when running the engine. Further, be careful not to
touch the belt or fan while the engine is operating.
4) Be careful not to touch hot metal parts, especial-
ly the radiator and exhaust system immediately af-
ter the engine has been turned off.
B: PRECAUTIONS IN TROUBLE DI-
AGNOSIS AND REPAIR OF ELEC-
TRIC PARTS
1) The battery cable must be disconnected from
the battery’s (–) terminal, and the ignition switch
must be set to the OFF position, unless otherwise
required by the diagnostics.
2) Securely fasten the wiring harness with clamps
and slips so that the harness does not interfere with
the body end parts or edges and bolts or screws.
3) When installing parts, be careful not to catch
them on the wiring harness.
4) When disconnecting a connector, do not pull the
wires, but pull while holding the connector body.
5) Some connectors are provided with a lock. One
type of such a connector is disconnected by push-
ing the lock, and the other, by moving the lock up.
In either type the lock shape must be identified be-
fore attempting to disconnect the connector.
To connect, insert the connector until it snaps and
confirm that it is connected securely.
6) When checking continuity between connector
terminals, or measuring voltage across the terminal
and ground, always contact tester probe(s) on ter-
minals from the wiring connection side. If the probe
is too thick to gain access to the terminal, use “mini”
test leads.
To check water-proof connectors (which are not
measurable from the wiring side), contact test
probes on the terminal side. Be careful not to bend
or damage the terminals.
7) Sensors, relays, electrical unit, etc., are sensi-
tive to strong impacts.
Handle them with care so that they are not dropped
or mishandled.
