Four-Wheel Drive (4WD) Low Switch

WARNING: This page is about a different car, the 2011 Ford F550 Super Duty and 2011 Ford F450 Super Duty. However, it is still accessible from the selected car via links, so may be relevant.

The 4WD  Low switch sends a ground signal to the IC  when the vehicle is in 4WD  Low. The PCM then receives a 4WD  Low status from the IC  and adjusts the transmission shift schedule accordingly.
