1CHECK INPUT SIGNAL OF BODY INTE-
GRATED UNIT USING SUBARU SELECT
MONITOR.
1) Turn the ignition switch to OFF.
2) Connect the Subaru Select Monitor to data
link connector.
3) Turn the ignition switch and Subaru Select
Monitor to ON.
4) Depress the brake pedal.
5) Read the input signal of stop light switch
from Subaru Select Monitor.
Select Monitor.>
Is “ON” displayed? Go to step 2.Go to step 3.
2CHECK DTC OF BODY INTEGRATED UNIT.
Check DTC of the body integrated unit.
Diagnostic Trouble Code (DTC).>
Is DTC (B0106) displayed? Repair or replace it
according to the
DTC.
Go to step 6.
3CHECK STOP LIGHT SWITCH.
Depress the brake pedal.
Does the stop light illuminate? Go to step 4.Check the stop
light system.
4CHECK HARNESS BETWEEN STOP LIGHT
SWITCH AND BODY INTEGRATED UNIT.
1) Turn the ignition switch to OFF.
2) Disconnect the connectors of body inte-
grated unit and stop light switch.
3) Measure the resistance of harness
between stop light switch and body integrated
unit.
Connector & terminal
(B65) No. 3 — (B281) No. 23:
Is the resistance more than 1
MΩ?
Repair the open
circuit of harness
between the body
integrated unit and
stop light switch.
Go to step 5.
5CHECK HARNESS BETWEEN STOP LIGHT
SWITCH AND BODY INTEGRATED UNIT.
Measure the resistance of harness between
stop light switch and chassis ground.
Connector & terminal
(B65) No. 3 — Chassis ground:
Is the resistance less than 1
Ω?
Repair the short
circuit of harness
between the body
integrated unit and
stop light switch.
Go to step 7.
6CHECK SHIFT LOCK SOLENOID.
1) Disconnect the connector of shift lock sole-
noid.
2) Connect the battery to connector terminal
of shift lock solenoid, and operate the solenoid.
Te r m i n a l s
No. 3 (+) — No. 4 (–):
Is the shift lock solenoid oper-
ating properly?
Go to step 7.Replace the shift
lock solenoid.
7CHECK SHIFT LOCK OPERATION.
1) Connect all the connectors.
2) Shift the select lever to “P” range.
3) Shift the select lever from “P” range to “R”
range.
Can the select lever shift from
“P” range to “R” range?
Check the body
integrated unit.
A temporary poor
contact of connec-
tor or harness may
be the cause.
