3. Operation
When the vehicle is parked and Chassis Ready Conditions are satised, the
engine idle speed may be controlled by selection of one of the four available
modes: RPM1, RPM2, a variable RPM, and Standby RPM. The preset RPM
modes may be adjusted via applying +12V or GND to the grey RPM Adjust
wire (see 2.5 Adjusting Values of RPM Settings, page 6).
Chassis Ready Conditions:
• No vehicle speed
• Parking brake set
• Shift selector in Park (or Neutral on F750)
• Accelerator not pressed
• Service brake not pressed
• Engine running and below 1000 RPM
• No Diagnostic Trouble Code (DTC). Check Engine light must be off.
NOTE: While the engine is in high idle, should the throttle be deactivated
by one of the Chassis Ready Conditions changing, the engine will return
to normal speed. The throttle will ash the diagnostic LEDs to indicate the
cause of the deactivation for ve seconds after Chassis Ready Conditions
are restored. Then it will reset and return the vehicle to high idle.
Modes of Operation:
Standby Mode
Function: Increase idle to minimum required to activate PTO
Activation: Apply +12V to Violet Wire on J1 Harness Input Group
Factory Calibration: 950 RPM
NOTE: A minimum of 910 RPM is required to enable PTO on 2020+
vehicles, so we do not recommend adjusting the Standby set-point below
the Factory Calibration.
Preset RPM Modes
Function: Increase idle to preset RPM values
Activation: RPM1: Apply +12 V to Pink Wire on J1 Input Group
RPM2: Apply +12V to Tan Wire on J1 Input Group
Factory Calibration: RPM1: 1500 RPM RPM2: 1200 RPM
Calibration Range: Varies based on vehicle model. Generally, 900 RPM
to 2200 RPM (gas) or 2800 RPM (diesel)
Variable RPM Mode
Function: Varies RPM as a function of voltage from customer-supplied
remote variable control
