Combination Switch (Wiper)
WIPER AND WASHER SYSTEMS
2. FRONT WIPER
1) Check with Subaru Select Monitor
When the front wiper switch is operated, check the
input signal using the Subaru Select Monitor.
(1) Connect the Subaru Select Monitor to data
link connector.
(2) Turn the ignition switch to ON.
(3) Select {Integ. unit} from main menu.
(4) Select the {Current Data Display & Save}.
(5) Check the input signal when the front wiper
switch is set to LO or HI.
2) Check the intermittent operation (inspection of
the wiper switch alone)
(1) Set the voltage meter between connector
terminal No. 7 (+) and No. 2 (–).
(2) Connect the battery between connector ter-
minal No. 7 (+) and No. 2 (–).
(3) Turn the wiper switch to INT.
(4) Connect the battery ground terminal to the
connector terminal No. 16 for five seconds.
(5) After connecting the battery ground terminal
for five seconds in step (4), connect the battery
positive terminal to the connector terminal No.
16 for five seconds.
(6) After connecting the battery ground terminal
and the battery positive terminal to the connec-
tor terminal No. 16 for five seconds each in step
(4) and (5), connect the ground terminal to the
connector terminal No. 16 again.
(7) Perform the step (1) to (6) above at MIN and
MAX position of the intermittent control switch.
If operation is not as specification, replace the
wiper switch assembly.
3) Inspect the vehicle speed response (With the
wiper switch installed on the vehicle)
(1) Operational check
Position the front wiper switch to INT, then mea-
sure the intermittent stationary time at each ve-
hicle speed.
If operation is not as specified, replace the
switch.
(2) Check vehicle speed signal
Raise the vehicle speed to 10 km/h (6 MPH) or
more, then measure the voltage between the
wiper switch connector and the chassis ground.
Terminals
No. 15 (+) — Chassis ground (–):
(3) Check the vehicle speed signal harness
Measure the resistance between the wiper
switch connector and the VDC control module.
Terminals
Wiper switch connector No. 15 — VDC con-
trol module No. 33:
Check Yes No
Is the input signal normal?
Finish the
diagnosis.
Replace the body
integrated unit.
