Inspection / Operation

1. INSPECT ONE TOUCH POWER WINDOW SYSTEM/CURRENT OF CIRCUIT (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 negative (-) terminal of the battery.
c. Connect the positive (+) lead from the battery to terminal 14 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 PTC opens some 4 - 90 seconds after the window stops going down, so that check must be made before the PTC operates.
If the operation is as specified, replace the driver door ECU.




2. INSPECT ONE TOUCH POWER WINDOW SYSTEM! CURRENT OF CIRCUIT (Using an ammeter with a current-measuring probe)
a. Remove the driver door ECU with connectors connected.
b. Attach a current-measuring probe to terminal 25 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 PTC opens some 4 - 90 seconds after the window stops going down, so that check must be made before the PTC operates.
If operation is as specified, replace the driver door ECU.








Inspect REAR POWER WINDOW SWITCH CONTINUITY
If continuity is not as specified, replace the switch.
