Tow Haul Switch
WARNING: This page is about a different car, the 2007 Ford Pickup, 2007 Ford F550 Super Duty, 2007 Ford F450 Super Duty, and 2007 Ford Cab & Chassis. However, it is still accessible from the selected car via links, so may be relevant.
The tow/haul switch is located on the end of the shift lever and is a momentary contact switch. The tow/haul switch provides a signal to the PCM when pressed by the driver, resulting in a change in shift and TCC scheduling. When the tow/haul switch has been pressed, the indicator light that is located on either the end of the shift lever or on the instrument panel will illuminate Tow/Haul - ON. When the switch is pressed again, tow/haul will be deactivated and the transmission control indicator lamp (TCIL) will turn off.
