Pinpoint Test I: The One-Touch Up/Down Feature is Inoperative - MKZ (LH or RH Front) or Fusion, Milan (LH front)

Refer to Wiring Diagram Set 100 (Fusion/Milan/MKZ, Fusion Hybrid/Milan Hybrid), Power Windows for schematic and connector information. Diagrams By Number

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 .

NOTE: The LH or RH front power window motor must be initialized whenever a new motor is installed.

NOTE: The LH or RH front power window motor must be de-initialized, then initialized whenever the front window motor is removed from the window regulator drum housing, a new window regulator is installed, a new window glass is installed, a new top run is installed or for any operation in which grease or lubricants are applied to the window regulator or glass run.

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
- LH or RH front window motor
- LH or RH front window control switch
- LH or RH front motor not initialized



PINPOINT TEST I: THE ONE-TOUCH UP/DOWN FEATURE IS INOPERATIVE - MKZ (LH OR RH FRONT) OR FUSION, MILAN (LH FRONT)

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.

-------------------------------------------------
I1 CHECK FOR POWER (B+) LOSS DURING LH OR RH FRONT 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 I2.

-------------------------------------------------
I2 DE-INITIALIZE, THEN INITIALIZE THE FRONT MOTOR


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

No
For LH window, GO to I3.
For RH window (MKZ only), GO to I4.

-------------------------------------------------
I3 CHECK THE LH FRONT WINDOW CONTROL SWITCH


- Ignition OFF.
- Disconnect: LH Front Window Control Switch C535A and C535B (MKZ) or C537A and C537B (Fusion, Milan).
- Carry out the LH front window control switch component test.

- Did the LH front window switch pass the component test?

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

No
INSTALL a new LH front window control switch. REFER to Window Control Switch Service and Repair. TEST the system for normal operation.

-------------------------------------------------
I4 CHECK THE LH and RH FRONT WINDOW CONTROL SWITCH


- Ignition OFF.
- Disconnect: For MKZ, LH Front Window Control Switch C535A, C535B and RH Front Window Control Switch C624.
- Carry out the LH front window control switch component test and the RH front window control switch component test.

- Did the LH and RH front window switches pass the component tests?

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

No
INSTALL a new front window control switch. REFER to Window Control Switch Service and Repair. TEST the system for normal operation.
