Combination Switch (Wiper)
WIPER AND WASHER SYSTEMS
2. FRONT WIPER
1) Check with Subaru Select Monitor
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 more than 10 km/h
(6 mph), then measure the voltage between the
wiper switch connector and the chassis ground.

1CHECK INPUT SIGNAL TO THE BODY INTE-
GRATED UNIT.
When the front wiper switch is operated, check
the input signal using the Subaru Select Moni-
tor.
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.
Is the input signal normal? Finish the diagno-
sis.
Replace the body
integrated unit.

DETECTING CONDITION:
•Defective combination meter
•Defective harness
TROUBLE SYMPTOM:
•TIRE PRESSURE WARNING LIGHT DOES NOT GO OFF
•“NO TROUBLE CODE” will be displayed on the Subaru Select Monitor.
NOTE:
When the tire pressure warning light is OFF and “NO TROUBLE CODE” is displayed on Subaru Select Mon-
itor, the system is in a normal condition.

Tire Pressure Warning Light/Trouble Indicator Light Illumination Pattern (DTC)
TIRE PRESSURE MONITORING SYSTEM (DIAGNOSTICS)
1) When the tire pressure warning light does not illuminate in accordance with this illumination pattern, there
must be an electrical malfunction.
2) When tire pressure warning light does not go off, check the tire pressure monitoring control module/warn-
ing light circuit and the combination meter circuit.
(DTC).>
NOTE:
If the problem is fixed while driving at approximately 40 km/h (25 MPH) after the tire pressure warning light
blinks/lights, the warning light goes out and the tire pressure monitor system operates normally. (If there is
a decrease in tire pressure, or malfunction of the system, the past malfunctions are displayed.)
B: TIRE PRESSURE WARNING LIGHT DOES NOT ILLUMINATE
DETECTING CONDITION:
•Defective combination meter
•Defective harness
TROUBLE SYMPTOM:
When the ignition switch is turned to ON (engine OFF), the tire pressure warning light does not come on (for
approximately 2 seconds).
