Right Operator Platform
(3) Implement electronic control module (ECM). (4) Power train electronic control module (ECM)

Implement electronic control module (3) and Power train electronic control module (4) are located in the right operator platform. Both electronic control modules may be accessed by removing the cover plate on the operator platform.

The Electrical System Schematic, Parts Manual, and Operation and Maintenance Manual should be used to locate electrical components and connectors to be serviced.

The following information is a guide to reading the tables on the back of the Electrical System Schematic.

  • The "Component Location" table uses white circles to mark the locations in the profile of the machine and in the area views. Alphabetical letters in the "Machine Location" column indicate a general area of the machine. Refer to the corresponding footnote at the end of the table for a description of the location.

  • The "Harness Connector Location" table uses white circles to mark the locations in the general view and in the area views. Alphabetical letters in the "Machine Location" column indicate a general area of the machine. Refer to the corresponding footnote at the end of the table for a description of the location.

Reference: For more information on the electrical system and the components, refer to the Service Manual module Schematic.

Reference: For more information on the operation of the electrical components of the machine, refer to the appropriate Parts Manual for your machine.
