2) Rear wiper motor circuit check

Step Check Yes No

1 CHECK INPUT OF REAR WIPER.

Check the input from body integrated unit

using Subaru Select Monitor.

1) Connect the Subaru Select Monitor to data

link connector.

2) Turn the ignition switch to ON.

2 CHECK OUTPUT OF BODY INTEGRATED

UNIT.

When the rear wiper switch is operated, check

the output using Subaru Select Monitor.

1) Turn the ignition switch to ON.

2) Operate the rear wiper switch to set to each

position of ON and INT.

3) At this time, check the output of body inte-

grated unit.

When it is set to ON, is ON out-

put continuously? When it is

set to INT, is ON/OFF output

Step Check Yes No

1 CHECK POWER SUPPLY CIRCUIT OF REAR

WIPER MOTOR.

1) Disconnect the harness connector of rear

wiper motor.

2) Turn the ignition switch to ACC.

3) Measure the voltage between the rear

wiper motor harness connector terminal and

chassis ground.

Connector & terminal

(D43) No. 1 (+) — Chassis ground (

−

):

Is the voltage more than 10 V? Go to step 2. • Check the fuse

(No. 23 in fuse &

relay box).

• Check the fus-

ible link (No. 6 in

main fuse box).

2 CHECK GROUND CIRCUIT OF REAR WIPER

MOTOR.

1) Turn the ignition switch to OFF.

2) Measure the resistance between the rear

wiper motor harness connector terminal and

chassis ground.

Connector & terminal

(D43) No. 3 — Chassis ground:

Is the resistance less than 10

Ω?

Go to step 3. Repair the open

circuit of rear wiper

motor ground

cable.

3 CHECK HARNESS BETWEEN BODY INTE-

GRATED UNIT AND REAR WIPER MOTOR.

1) Turn the ignition switch to OFF.

2) Disconnect the harness connector of body

integrated unit.

3) Disconnect the harness connector of rear

wiper motor.

4) Measure the resistance between the har-

ness connector terminals of body integrated

unit and rear wiper motor.

Connector & terminal

(B280) No. 1 — (D43) No. 2:

(B280) No. 8 — (D43) No. 4:

Is the resistance less than 10

Ω?

Go to step 4. Repair the open
