What is an ECU?

The ECU-S1 is a high precision electronic controller that provides automatic steering capability to the vehicle. The ECU-S1 controller receives guidance information from the Display device and sends steering commands to the vehicle. This Operator’s Manual provides information on how to setup, configure, and manage the various settings on the ECU-S1 controller and how to navigate through the software menus.

The ECU-S1 (the brain of the system) controller is compatible with multiple Displays. Please refer to the Display Operator’s Manual or contact your AutoSteer dealer for specific instructions on how to connect the ECU-S1 system components to the Display. Also refer to the Display Operator’s Manual for information on how to access ECU-S1 software menus and options. For information about setting up farms, fields, jobs, guidance patterns, and other Display related functions, please refer to your Display Operator’s Manual.

The ECU-S1 can be installed easily on most agricultural vehicle makes and models. This chapter provides basic information on how the ECU-S1 system components are organized and installed. Refer to the Installation Manual that comes with the vehicle installation kit for more details on the complete installation of the ECU-S1 system.
