Pinpoint Test G: The One-Touch Up/Down Feature is Inoperative - LH Front Window Only

Refer to Wiring Diagrams Set 100, Power Windows for schematic and connector information. Electrical Diagrams

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

NOTE: The power window motor must be initialized whenever a new motor is installed.

NOTE: The power window motor must be de-initialized, then initialized whenever the 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:

- LH front window motor not initialized

- LH front window motor

- LH front window control switch

PINPOINT TEST G : THE ONE-TOUCH UP/DOWN FEATURE IS INOPERATIVE - LH FRONT WINDOW ONLY

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.

G1 CHECK FOR POWER (B+) LOSS DURING WINDOW OPERATION

- Verify if power (B+) was lost during window operation.

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

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

No
GO to G2.

G2 DE-INITIALIZE, THEN INITIALIZE THE LH FRONT WINDOW MOTOR

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

Is the one-touch up feature operating correctly?

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

No
GO to G3.

G3 CHECK THE LH FRONT WINDOW CONTROL SWITCH

- Ignition OFF.

- Disconnect: LH Front Window Control Switch C504.

- Carry out the LH front window control switch component test.

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

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

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