Implement Control Connector
The OEM oil & gas transmission control will be required to support 12 Volt and 24 Volt systems. The transmission hardware is dependent on the system voltage and therefore the start relay and transmission solenoids must be changed accordingly.The ECM makes decisions based on information that is input to the ECM and information in memory. The ECM then sends a corresponding response through the outputs. The inputs and outputs of the implement ECM are connected to the machine harness. Use contact connectors "J1" and "J2".The machine has several input devices. Input devices inform the ECM of the operating conditions of the machine. The machine has inputs from switches and sensors. Switches provide an open, a ground or a +battery to the inputs of the implement ECM. Sensors provide a constantly changing signal to the ECM.The implement ECM responds to decisions by sending electrical signals through the outputs. The outputs can create an action or the outputs can provide information to the ECM. Refer to System Operation, Troubleshooting, Testing and Adjusting, KENR8291, "Power Train Electronic Control System" for detailed information concerning the Transmission Control Module.
