2. 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
approximately 7 A.
(e) Check that the current increases up to 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.
3. 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
approximately 7 A.
(e) Check that the current increases up to 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 operation is as specified, replace the master switch.

BATTERY
PRECAUTION
In order to prevent a short circuit while doing work on the electri-
cal circuit such as disconnecting a connector, first turn off the
ignition switch and disconnect the negative (-) terminal cable
from the battery before starting work.
HINT:
When battery voltage is required for operation of a functioning
part, connect the cable to the battery when needed, and
promptly disconnect it when no longer necessary.
CAUTION:

Work must be started after 90 seconds from the time
the ignition switch is turned to the ºLOCKº position
and the negative (-) terminal cable is disconnected
from the battery.

To avoid erasing the memory of each memory sys-
tem, never use a back-up power supply from outside
the vehicle.

If circuit is as specified, try replacing the amplifier with a new
one. If the circuit is not as specified, inspect the circuits con-
nected to other parts.
(b) Connect the connector to A/C amplifier and inspect the
wire harness connector from the back side, as shown in
the chart below.
Tester conditions:
