2. INSPECT POWER WINDOW MASTER SWITCH ILLU-
MINATION
(a) Set the window lock switch to the unlock position.
(b) Connect the positive (+) lead from the battery to terminal 7 and the negative ( −) lead to terminal 1, and check that
all the illuminations light up.
(c) Set the window lock switch to the lock position, and check that all the passenger’s power window switch illumina-
tions go out.
If operation is not as specified, replace the master switch.
3. Using an ammeter: INSPECT ONE TOUCH POWER WINDOW SYSTEM
(a) Disconnect the connector from the master switch.
(b) Connect the positive (+) lead from the ammeter to termi- nal 6 on the wire harness side connector and the negative
(−) lead to negative terminal of the battery.
(c) Connect the positive (+) lead from the battery to terminal 13 on the wire harness side connector.
(d) As the window goes down, check that the current flow is up to approximately 7 A.
(e) Check that the current increases approximately 14.5 A or more when the window stops going down.
HINT:
The circuit breaker opens some 4 − 40 seconds after the win-
dow stops going down, so that check must be made before the
circuit breaker operates.
If the operation is as specified, replace the master switch.

4. Using an ammeter with a current − measuring probe:
INSPECT ONE TOUCH POWER WINDOW SYSTEM
(a) Remove the master switch with connector connected.
(b) Attach a current−measuring probe to terminal 6 of the
wire harness.
(c) Turn the ignition switch ON, and set the power window switch in the down position.
(d) As the window goes down, check that the current flow is up to approximately 7 A.
(e) Check that the current increases approximately 14.5 A or more when the window stops going down.
HINT:
The circuit breaker opens some 4 − 40 seconds after the win-
dow stops going down, so check must be made before the cir-
cuit breaker operates.
If operation is as specified, replace the master switch.
