Test E: The One-Touch Up/Down Feature Is Inoperative
PINPOINT TEST E: THE ONE-TOUCH UP/DOWN FEATURE IS INOPERATIVENOTE:
- A new LH front power window motor will not operate in one-touch up mode until initialized. Refer to Window Motor Initialization. Testing and Inspection
- The LH front power window motor must be initialized whenever a new motor is installed.
- The LH front power window motor must be de-initialized, then initialized whenever the LH 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
The LH front power window control switch receives power from the delayed accessory relay through circuit CBP47 (GN/BU) and is grounded through circuit GD133 (BK). When the LH front window control switch is pressed to the up position, the LH front motor receives power through circuit CPW11 (BU/GY). When the LH front window control switch is pressed to the down position, the LH front motor receives power through circuit CPW10 (YE/VT). When the LF window motor receives a ground signal on circuit CPW29 (VT/GY), the LF window motor will enter one-touch down.
This pinpoint test is intended to diagnose the following:
- Wiring, terminals or connectors
- Inoperative LH front window motor
- Inoperative LH front window control switch
- LH front motor not initialized
