A: INSPECTION

1. WITH SUBARU SELECT MONITOR

CAUTION:
Check that the rear window defogger timer is in initial setting or customize setting before performing 
inspection.

2. HEAT WIRE INSPECTION

CAUTION:
Use a dry and soft cloth when wiping stain off 
on the glass. Move it along the heat wire to 
avoid damage to heat wire.
1) Turn the ignition switch to ON.
2) Turn the defogger switch to ON.
3) Wrap the tips of tester probe with aluminum foil
to avoid damage to heat wire.

4) Measure the voltage at heat wire center with DC
voltmeter.

Standard voltage:

Approx. 6 V

NOTE:
• If the measured value is 12 volts, heat wire is
open between heat wire center and positive (+) ter-
minal of tester probe.
• If zero volt, heat wire is open between wire cen-
ter and ground.

CHECK INPUT SIGNAL TO BODY INTE-
GRATED MODULE.
Check the input signal when the rear window 
defogger switch is operated using Subaru 
Select Monitor.
1) Connect the Subaru Select Monitor to data 
link connector.
2) Turn the ignition switch to ON.
3) Select the {Integ. unit} from the «Main 
Menu».
4) Select the {Current Data Display & Save}.
5) Check the input signal when the rear win-
dow defogger switch is set to ON.

Does the rear defogger switch 
turn to OFF in 15 minutes after 
set to ON? Or does it repeat 15 
minutes operation and 2 min-
utes stop?

END.

5) Connect the tester probe of voltmeter positive
lead to positive terminal of heat wire, and move the
tester probe of negative lead along the heat wire up
to the negative terminal end. If voltage changes
from zero to several volts while moving the tester
probe, heat wire is open at the point where voltage
changed.

B: REPAIR

1) Clean the broken point with alcohol or white gas-
oline.
2) Mask both side of the heat wire with thin film.
3) Apply conductive silver composition (DUPONT
No. 4817) to the broken point.

4) After repair, check the heat wire.
