Component Tests

INSPECT ONE TOUCH POWER WINDOW SYSTEM CURRENT OF CIRCUIT (Using an ammeter)
a. Disconnect the connector from the driver door ECU.
b. Connect the positive (+) lead from the ammeter to terminal 8 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 17 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.




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 7 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.

CHECKING OF THE JAM PROTECTION FUNCTION

NOTE: Never, ever be caught any part of your body when checking.

HINT: In case of performing resetting of the limit switch, do checking after repeating up and down of the glass with automatic operation.

a. Confirmation of AUTO up operation:
Confirm that the window will be fully close with AUTO up operation.
b. Checking of the operation of the jam protection function:
1. Move up the window with AUTO up operation and check that the window will go down when it touches the handle of the hammer setted.
2. Confirm that the window will then stop going down about 200 mm.

HINT: In case of removing the glass, glass guide, regulator and etc. be sure to perform checking of the jam protection function.
