Right Operator Control Unit Connector "J2"The right operator control unit monitors input signals from the following components in the propel system:
Right decelerator sensor terminal "J2-16"
Right parking brake switch terminal "J2-30" and terminal "J2-31"
Right propel mode switch terminal "J2-54" and terminal "J2-55"The right operator control unit simultaneously monitors the condition of the circuit at terminal "J2-30" and the circuit at terminal "J2-31" in order to determine the position of the right parking brake switch. When the circuit at terminal "J2-30" is grounded and the circuit at terminal "J2-31" is floating, the control unit determines that the right parking brake switch is in the OFF position. When the circuit at terminal "J2-30" is floating and the circuit at terminal "J2-31" is grounded, the control unit determines that the right parking brake switch is in the ON position. The right operator control unit simultaneously monitors the condition of the circuit at terminal "J2-54" and the circuit at terminal "J2-55" in order to determine the position of the right propel mode switch. When the circuit at terminal "J2-54" is grounded and the circuit at terminal "J2-55" is floating, the control unit determines that the right propel mode switch is in the TRAVEL position. When the circuit at terminal "J2-54" is floating and the circuit at terminal "J2-55" is grounded, the control unit determines that the right propel mode switch is in the MANEUVER position. When the circuit at terminal "J2-54" is floating and the circuit at terminal "J2-55" is floating, the control unit determines that the right propel mode switch is in the PAVE position.Terminal "J2-22" of the right operator control unit provides a common ground for the following digital input devices in the propel system:
Parking brake switch
Propel mode switchThe right operator control unit controls the ground path for the right operator station status indicator. When the machine electronic control system determines that the right operator station is active, the right operator control unit connects terminal "J2-13" to ground. When the left operator station is active, terminal "J2-13" is open.The CAN lines provide high speed communication between the control units for the machine and the engine ECM. The CAN requires a positive line and a negative line. The right operator control unit contains two positive CAN lines and two negative CAN lines. The positive lines are connected to terminal "J2-56" and to terminal "J2-67" of the right operator control unit. The negative lines are connected to terminal "J2-68" and to terminal "J2-69" of the right operator control unit.

Rear of Engine (15) Connector "J1" (16) Connector "J2" (17) Engine ECMThe door on the right side of the machine provides access to engine ECM (17). The engine ECM has two 64 pin connectors. Connector "J1" (15) transfers information between the machine harness and the engine ECM. Connector "J2" (16) monitors components which are located on the engine.Engine ECM (17) transfers engine speed information to machine ECM (9). The machine ECM uses this information to control machine speed.
