Preset PTO Mode: Notes

WARNING: This page is about a different car, the 2008 GMC Sierra, 2008 GMC Cab & Chassis Sierra, 2008 Chevrolet Silverado, and 2008 Chevrolet Cab & Chassis Silverado. However, it is still accessible from the selected car via links, so may be relevant.

Preset PTO can only be used when the vehicle is not moving. The engine speed is initially set to a standby engine speed of 800 RPM. This provides an initial start-up engine speed to match the engagement of the PTO load. The PTO standby engine speed can be reprogrammed to higher speeds.

Choose one of two presets by pressing and releasing the PTO In-cab or remote PTO SET in the SET - or RES + switch positions:

Speed 1: Pressing the SET - position results in a preset speed of 1250 RPM
Speed 2: Pressing the RES + position results in a preset speed of 1700 RPM

Pressing the 0 switch position on the PTO in-cab switch or moving the remote PTO enable switch to OFF results in the return of the engine speed back to normal idle. The PTO load relay is also disengaged.

Maximum PTO Operating Speed: During PTO operation, the accelerator pedal can be pressed to adjust the engine speed. To protect the PTO from overspeed, the PTO system will disengage when the engine speed exceeds 2100 RPM.

The Stationary PTO Mode provides both in-cab and remote controls. The in-cab controls are enabled as the factory preset. The remote controls are disabled. This factory preset configuration can be reprogrammed to enable the remote controls, and disable the in-cab PTO controls.
