Power Window Control System: Inspection

Using an ammeter:
INSPECT ONE TOUCH POWER WINDOW SYSTEM/ CURRENT OF CIRCUIT
1. Disconnect the connector from the master switch.
2. 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.
3. Connect the positive (+) lead from the battery to terminal 14 on the wire harness side connector.
4. As the window goes down, check that the current flow is approximately 7 A.
5. 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.
