Tow/Haul (Diesel Engine Vehicles)
WARNING: This page is about a different car, the 2008 Ford Pickup, 2008 Ford F550 Super Duty, 2008 Ford F450 Super Duty, and 2008 Ford Cab & Chassis. However, it is still accessible from the selected car via links, so may be relevant.
When the Tow/Haul switch is pressed, the Transmission Control Indicator Lamp (TCIL), located in the Instrument Cluster (IC), will illuminate the graphics "Tow/Haul ON." Operation of the TCIL is controlled by the PCM to alert the driver that Tow/Haul mode has been activated. Pressing the TCS again will turn off the TCIL. Turning off the engine will return the TCIL to the default position (Tow/Haul OFF).
The PCM may command steady illumination of the TCIL if certain faults are detected in monitored sensors, solenoids or apply components.
