Glass, Frames and Mechanisms

Pinpoint Test J: 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

NOTE: All vehicles are equipped with one-touch up/down feature on the LH front window. All MKZ and some Fusion vehicles are equipped with one-touch up/down feature for both LH and RH front windows.

NOTE: A new LH or RH front power window motor will not operate in one-touch up or one-touch down mode until initialized. Refer to Window Motor Initialization .

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:

- B(+) power lost during LH or RH front window operation

- Power window motor not initialized

- Power window motor

- Window control switch

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

NOTICE: Use the correct probe adapter(s) from the Flex Probe Kit when making measurements. Failure to use the correct probe adapter(s) may damage the connector.

J1 CHECK FOR POWER (B+) LOSS DURING LH OR RH FRONT POWER WINDOW OPERATION

- Verify if power (B+) was lost during LH or RH front window operation.

Was power (B+) lost while the LH or RH front window was in operation?

Yes
RAISE the LH or RH front window to the fully CLOSED position. VERIFY the window glass stalls into the upper header seal. The front window should function normally. TEST the system for normal operation.

No
GO to J2.

J2 DE-INITIALIZE, THEN INITIALIZE THE FRONT POWER WINDOW MOTOR

- De-initialize the front power window motor, then carry out the front power 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 front power window motor lost initialization.

No
For LH window, GO to J3.

For RH window, GO to J4.

J3 CHECK THE MASTER WINDOW CONTROL SWITCH

- Ignition OFF.

- Disconnect: Master Window Control Switch C535A and C535B (MKZ or Fusion if RH front window is equipped with one-touch up/down) or C537A and C537B (Fusion if RH front window is not equipped with one-touch up/down).

- Carry out the master window control switch component test.

Did the master window switch pass the component test?

Yes
INSTALL a new LH front power window motor. REFER to Window Regulator Motor . TEST the system for normal operation.

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

J4 CHECK THE LH AND RH FRONT WINDOW CONTROL SWITCH

- Ignition OFF.

- Disconnect: Master Window Control Switch C535A and C535B.

- Disconnect: RH Front Window Control Switch C624.

- Carry out the master window control switch component test and the RH front window control switch component test.

Did both the master window control switch and RH front window switch pass the component tests?

Yes
INSTALL a new RH front power window motor. REFER to Window Regulator Motor . TEST the system for normal operation.

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