CURRENT OF CIRCUIT
- + (a) Disconnect the connector from the master switch.
(b) Connect the positive (+) lead from the ammeter to termi-
nal 1 on the wire harness side connector, and the nega-
tive (-) lead to negative terminal of the battery.
(c) Connect the positive (+) lead from the battery to terminal
I21996 2 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
1 2 14.5 A or more when the window stops going down.
HINT:
- + The circuit breaker opens for 4 - 40 seconds after the window
stops going down, so that check must be made before the cir-
cuit breaker operates.
If the operation is as specified, replace the master switch.

INSPECT ONE TOUCH POWER WINDOW SYSTEM/
CURRENT OF CIRCUIT
(a) Remove the master switch with the connector connected.
(b) Attach a current-measuring probe to terminal 3 of the
wire harness.
(c) Turn the ignition switch ON and set the power window
switch in the down position.
I21998 (d) As the window goes down, check that the current flow is
approximately 7 A.
3 (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 for 4 - 40 seconds after the window
stops going down, so the check must be made before the circuit
breaker operates.
If the operation is not as specified, replace the master switch.
