Power Train ECM control system | |
The Power Train control module (ECM) enable electronic control for the transmission. The ECM electronically controls the operation of the braking system. If the machine is equipped with the electronic hydraulic implement system, the ECM will control the solenoids that enable the movement of the dozer blade.
Machines that are equipped with the electronic hydraulic implement control system can also be equipped with the Attachment Ready Option (ARO). The ARO equipped machines have several electrical components in the system that enable the ECM to control the Accugrade GPS system that can be installed on the machine. The wiring harness on ARO equipped machines is configured for mating connections to the electrical components of the Accugrade GPS system.
D6R Series III and D6T machines can be equipped with the Variable Power Angle Tilt (VPAT) dozer blade. Machines that are equipped with the VPAT blade are fitted with a hydraulic manifold with two proportional solenoids that will enable the ECM to control the angle of the dozer blade. The angle of the blade is determined by a thumb rocker switch position sensor on the blade control handle which will provide input information to the ECM.
For more information on Power Train ECM controlled features on the tractor, refer to Systems Operation, "Features" in this manual.
