Test F: The One-Touch Up/Down Feature Is Inoperative - LF

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

Normal Operation
Under normal operation, the LF power window motor microprocessor receives power at all times through circuit SBP01 (RD) and from the accessory delay relay through circuit CBP41 (BU). Ground is provided at all times through circuit GD143 (BK/VT). The master window control switch provides voltage input to the power window motor microprocessor through circuit CPW10 (YE/VT) to operate the driver window down, and voltage input through circuit CPW11 (BU/GY) to operate the driver window up. To operate the one-touch feature, the master window control switch provides a ground input to the LF power window motor microprocessor through circuit CPW29 (VT/GY) in addition to the up or down request.

This pinpoint test is intended to diagnose the following:
- Fuse(s)
- Wiring, terminals or connectors
- Window control switch
