Switches
Switches provide one of the following types of inputs to the ECM:
Open
Ground
+BatterySwitches are devices that have two states, opened or closed.
When a switch is open, no signal is provided to the corresponding input of the ECM. This condition is also referred to as floating.
When a switch is closed, a ground signal or a +battery signal is provided to the ECM. Primary Steering Pressure Switch
Illustration 8 g02731847
The primary steering pressure switch is a pressure switch that is used to determine if there is sufficient pressure in the primary steering system. This switch has two outputs, one that is normally open and one that is normally closed. When the pressure in the primary steering system drops below the threshold, the outputs become closed and open respectively.Kickout Switches

(7) Raise Kickout Switch (8) Lower Kickout Switch (9) Tilt Kickout SwitchThe kickout switches are now on the new keypad, which is located on the right side panel in the cab.The raise kickout button, the lower kickout switch, and the tilt kickout switch all operate the same. When setting a kickout position, operate the appropriate implement control lever to set the lift arms or bucket to the desired kickout position and then return the control lever to the HOLD position. When a kickout button is pressed, a signal is sent over the CAN B Data Link to the Implement ECM via the Power Train ECM. The Implement ECM stores the current lift or tilt cylinder position, flashes the center LED on the switch panel twice, then illuminates the center LED and sounds an alarm indicating that the kickout position is set. The kickout position can be disabled with Advisor or Cat ET. When disabled, the Implement ECM turns off the center LED.Implement Lockout Switch

Implement (Hydraulic) Lockout SwitchThe Implement ECM will control the operation of the Implement Pilot Supply Solenoid according to the position of the Hydraulic Lockout Switch. Certain fault conditions will also cause the Implement ECM to use the solenoid valve to disable hydraulic operation. The ECM will disable the operation of the Implement System when the switch is in the LOCK position.When the switch is in the UNLOCK position, the normally closed switch contacts will ground the input circuit at ECM contact J1-34. When the ECM detects this grounded circuit, the ECM will energize the Implement Pilot Supply Solenoid. The energized solenoid will allow pilot oil to be supplied to the implement control valve. When the switch is in the LOCK position, the normally open switch contacts will ground the input circuit at ECM contact J1-33. When the ECM detects this grounded circuit, the ECM will de-energize the ON/OFF output for the Implement Pilot Supply Solenoid. Pilot oil will be blocked from the implement control valve.PCS (Payload Control System) Store Switch

PCS Store SwitchThe PCS Store Switch is installed on the machine when the Payload Control System attachment is installed.When the Payload Control System feature is active, the PCS Store Switch is used to store the current truck information in the
