Activation Of The Gear Shift Solenoids
The Machine ECM will allow the operator to select between two travel speed modes. The modes are Gear 1 and Gear 2. The travel speed mode is selected from the Gear Select Button on the Soft Switch Panel (SSP). Pressing the button will cycle between the two modes. The LED indicator will be illuminated for the mode that is active. The SSP travel mode status information is supplied to the ECM over the J1939 Data Link. In order for the ECM to enable the low travel speed, the following conditions must be correct.
Gear 1 is requested by the operator.
The parking brake is OFF.
The left console is in the DOWN position.The Travel Pedal is mechanically connected to the Travel Pilot Pressure System. When the Travel Pedal is pressed in either the FORWARD or the REVERSE direction, the ECM will enable the travel function if machine conditions are correct. Once the travel function is enabled, the ECM will energize "Transmission Gear Shift 1" Solenoid in order to set the Travel Motor to low speed. When Gear 2 is selected and the machine conditions that are listed above are correct, the ECM will energize "Transmission Gear Shift 2" Solenoid in order to set the Travel Motor to high speed. When the attachment Joystick Steering function is installed and active, the ECM will limit the active gear mode to Gear 1. If Gear 2 is selected, the LED indicator will flash. The ECM will shift to Gear 2 when the Joystick Steer function is no longer active.If both solenoids are activated at the same time, a diagnostic code will activate. The Monitor will display a "POWERTRAIN ERROR" message and machine travel will be disabled.If the Back Up Mode is enabled. Most of the machine functions will be disabled and the engine speed will be limited. The ECM will only allow travel operation in Gear 1.ReferenceFor more information on Travel Activation, and Travel Pedal operation, refer to Systems Operation, "Travel Activation Function"Travel Motor Control

Travel Motor Control component connectionsThe Travel Motor Swash Plate Angle Solenoid is used by the Machine ECM to adjust the swash plate angle on the Travel Motor. The ECM activates this solenoid in order to increase or decrease the amount of hydraulic oil flow that is available to the travel motor. This function will result in an increase or a decrease in machine travel speed within the selected gear.The ECM will use input data from the Travel Pedal Position Sensor, the Transmission Speed Sensor, and the maximum machine travel speed parameter to determine the correct output current for the swash plate solenoid.The ECM will use an internal formula calculation in order to determine machine ground speed. This formula considers the radius of the wheels, the axle ratio, and the transmission speed. If the ECM detects that machine ground speed is 7 km/h (4.3 mph) over the defined maximum machine speed parameter, a Level 2 Event for "TRANSMISSION OVERSPEED" will be activated.To
