GRATED UNIT USING SUBARU SELECT
MONITOR.
Read the input signal of stop light switch from
Subaru Select Monitor.

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) Depress the brake pedal.
2) Measure the voltage between body inte-
grated unit and chassis ground.
Connector & terminal
(B281) No. 23 (+) — Chassis ground (–):
Is the voltage more than 9 V? Go to step 5.Repair the open or
short circuit of har-
ness between the
body integrated
unit and stop light
switch.
5CHECK 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.
6CHECK SHIFT LOCK SOLENOID.
1) Turn the ignition switch to OFF.
2) Disconnect the connector of shift lock sole-
noid.
3) 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 OPERATION.
1) Connect all the connectors.
2) Turn the ignition switch ON. (Engine OFF)
3) Shift the select lever to “P” range.
4) Depress the brake pedal.
5) Shift the select lever from “P” range to “R”
range.
Can the select lever shift from
“P” range to “R” range?
A temporary poor
contact of connec-
tor or harness may
be the cause.
Check the body
integrated unit.

Pipe.> Muffler.>
14) Inspect the following items. When a malfunc-
tion is found in the inspection, adjust the select ca-
ble. Cable.>
(1) Engine starts when the select lever is in “P”
and “N” range, but not in other ranges.
(2) Back-up light illuminates when the select le-
ver is in the “R” range, but not in other ranges.
(3) Select lever and indicator positions are
matched.

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.

Basic Diagnostic Procedure
WIRING SYSTEM
•Each connector number shown in the wiring dia-
gram corresponds to that in the wiring harness. The
location of each connector in the actual vehicle is
determined by reading the first character of the
connector (for example, a “F” for F8, “i” for i16, etc. )
and the type of wiring harness. The first character
of each connector number corresponds to the area
or system of the vehicle.
