C: INSPECTION
1. MAIN SWITCH
• Driver’s seat
CAUTION:
Since the driver’s side power window switch is
controlled by CPU, do not check continuity for
switch alone with the circuit tester. Performing
continuity check with circuit tester may dam-
age the driver’s side power window switch cir-
cuit.
Check output from the power window main switch
to driver’s side motor using the oscilloscope func-
tion in the Subaru Select Monitor.
1) Disconnect the ground cable from battery.
2) Remove the power window main switch. <Ref. to
GW-9, REMOVAL, Power Window Control
3) Connect the battery and the Subaru Select Mon-
itor to the power window main switch connector.
CAUTION:
Never mix up the terminals when connecting
the power window main switch connector and
battery. If connected to a wrong terminal, the
power window main switch may be damaged.
NOTE:
• When the battery is connected to the power win-
dow main switch, the letters “AUTO” on the driver’s
side knob illuminates.
• For detailed procedures, refer to “Subaru Select
Monitor Operation Manual”.
4) Operate the driver’s side power window switch
knob and check the output.
NOTE:
Since output time during window UP operation is
extremely short, it cannot be checked without using
a measuring instrument such as oscilloscope. Out-
put is constantly produced while the knob is operat-
ed for window DOWN operation.
5) Replace the power window main switch if the in-
spection result is not within the standard value.
(1) Power window main switch connector (16
poles)
(2) Power window main switch connector (3 poles)
