In-cab PTO Switch

WARNING: This page is about a different car, the 2009 GMC Sierra, 2009 GMC Cab & Chassis Sierra, and 2009 Chevrolet Silverado. However, it is still accessible from the selected car via links, so may be relevant.

The PTO switch is mounted in the right side of the center instrument panel. The PTO switch is a four position rocker type: 1, 0, SET - and RES +. When the PTO 1 position is depressed, the PTO relay will be energized by the PTOM. A PTO LED indicator is integrated with the switch. The indicator will illuminate, flashing at a 0.25 second interval rate when the PTO relay is energized. The indicator illuminates solid once the PTO load feedback signal confirms the load has been engaged or after 3 seconds if load feedback is not utilized by the PTO system. The indicator will flash at a 1 second interval rate when PTO memory speed is retained. Depressing the 0 position turns the PTO system off. The PTO LED will turn off once engine speed reaches base engine idle, at which time the PTO relay is de-energized.
