Electronic Control Modules
Machine ECM
Illustration 1 g02579378
Location of machine ECMThe electronic control module (ECM) is located under the floorboard in the cab, directly in front of the operator seat. The ECM receives input from sensors, controls, and the CAN A system. The ECM uses this input in order to control the operation of the outputs of the ECM, including the implement control valves and the steering hydraulic control. These outputs control solenoid valves, which receive signals of variable proportion from the ECM in order to control the operation of the machine. The inputs and outputs of the ECM are joined to the machine harness by two connectors. Each of the two connectors has 70 contacts.ECM 2
Illustration 2 g03508476
Location of ECM 2The second electronic control module (ECM) is located under the right side access panel near the rear of the machine. ECM 2 communicates with the machine ECM through CAN A and is used to control some of the implement inputs and outputs. ECM 2 only has one connector with 70 contacts.Operator Controls
Differential Steering Control
Illustration 3 g03508478
Location of steering control handleThe steering handle is located to the left of the operator seat. The steering handle is used to control the hydraulic steering system. The steering handle contains two sensors that send a PWM signal to the machine ECM.Hydraulic System Sensors
Steering Speed Sensor
