3. 2 door models:
INSPECT ONE TOUCH POWER WINDOW SYSTEM
(Using an ammeter)
a. Disconnect the connector from the master switch.
b. Connect the positive (+) lead from the ammeter to terminal 3 on the wire harness side connector and the negative (-) lead to the negative (-) terminal of the battery.
c. Connect the positive (+) lead from the battery to terminal 4 on the wire harness side connector.
d. As the window goes down, check that the current 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 for 7 - 13 seconds after the window stops going down, so that check must be made before the circuit breaker operates.

If operation is not as specified, replace the master switch.




4. 2 door models:

(Using an ammeter with a current - measuring probe)
a. Remove the master switch with connector connected.
b. Attach a current - measuring probe to terminal 9 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 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 for 7 - 13 seconds after the window stops going down, so that check must be made before the circuit breaker operates.

If operation is not as specified, replace the master switch.




5. 4 door models:
INSPECT ONE TOUCH POWER WINDOW SYSTEM
(Using an ammeter)
a. Disconnect the connector from the master switch.
b. Connect the positive (+) lead from the ammeter to terminal 1 on the wire harness side connector and the negative (-) lead to the negative terminal of the battery.
c. Connect the positive (+) lead from the battery to terminal 5 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 window stops going down, so that check must be made before the circuit breaker operates.

If the operation is as specified, replace the master switch.




6. 4 door models:
INSPECT ONE TOUCH POWER WINDOW SYSTEM
(Using an ammeter with a current - measuring probe)
a. Remove the master switch with connector connected.

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 for 4 - 40 seconds after the window stops going down, so that Check must be made before the circuit breaker operates.

If operation is as specified, replace the master switch.







7. INSPECT PASSENGER'S POWER WINDOW SWITCH CONTINUITY
