Test G: The One-Touch Up/Down Feature Is Inoperative - RF

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

Normal Operation
Under normal operation, the RF power window motor microprocessor receives power at all times through circuit SBP04 (GN/RD) and from the accessory delay relay through circuit CBP41 (BU). Ground is provided at all times through circuit GD138 (BK/WH). The master window control switch or RF window control switch provides voltage input to the power window motor microprocessor through circuit CPW19 (VT) to operate the RF window down, and voltage input through circuit CPW20 (WH/OG) to operate the RF window up. To operate the one-touch feature, the master window control switch or RF window control switch provides a ground input to the RF power window motor microprocessor through circuit CPW31 (GN/WH) 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
