Pinpoint Test K: The One-Touch Up/Down Feature is Inoperative

Refer to Wiring Diagram Set 100, Power Windows for schematic and connector information [1][2]Diagrams By Number.

Normal Operation

During normal operation, when the window control switch is pressed to the second detent position to request an auto up or auto down operation, the window control switch provides a 12-volt signal on both the up and down line simultaneously. During an auto up or auto down request, the window motor determines intended window direction by the signal first received (first detent position). If the window control switch is pressed too quickly to the second detent position (less than 5 milliseconds of time between first detent signal and second detent signal), the window motor will not be able to determine the intended direction request and will not operate until the window control switch is released and pressed again.

This pinpoint test is intended to diagnose the following:

- Window motor not initialized

- Window control switch

- Window motor

PINPOINT TEST K : THE ONE-TOUCH UP/DOWN FEATURE IS INOPERATIVE

K1 DE-INITIALIZE, THEN INITIALIZE THE DOOR WINDOW MOTOR

- De-initialize the suspect door window motor, then carry out the window motor initialization procedure. Refer to Window Motor Initialization .

Is the one-touch up/down feature operating correctly?

Yes
The system is operating normally at this time. The window motor lost initialization.

No
GO to K2.

K2 CHECK THE SUSPECT WINDOW CONTROL SWITCH

- Ignition OFF.

- Disconnect: LH Front Window Control Switch C504 or RH Front Window Control Switch C604.

- Carry out the component test for the suspect door window control switch.

Did the door window control switch pass the component test?

Yes
INSTALL a new LH or RH front window motor. REFER to Window Regulator Motor - Front Door . INITIALIZE the front window motor. REFER to Window Motor Initialization . TEST the system for normal operation.

No
INSTALL a new LH or RH window control switch. REFER to Window Control Switch . TEST the system for normal operation.
