PROBLEM

Show/hide table

New power train system software, implement system software, and Messenger software need to be installed on certain 14M Motor Graders.

SOFTWARE CHANGES

POWER TRAIN:

-Implementation of a directional shift strategy that utilizes TOS and machine grade (if a slope sensor is installed) to improve powertrain durability.
-Improvement to support a "Manual Differential Lock Override" feature to allow the operator to manually engage the differential lock under certain circumstances when the "Automatic Differential Lock" feature is active.

IMPLEMENT AND STEERING:

-Enhancement to the machine articulation lockout functionality to add the new "Locked Out While Stationary" configuration to prevent articulation when the machine travel speed is zero.
-Improvements to the activation logic for the E2085 (Invalid Articulation Response Detected) Event to open the threshold for activation from 3.5 degrees of articulation movement in a 3 minute period to 5 degrees to reduce unnecessary events.
-Enhancement to the Wheel Lean, Center Shift, and Circle functionality to smooth operation.

MESSENGER:

-Improvements to allow precise adjustment of the articulation gauge needle in the instrument cluster to ensure it is centered when the machine is in the neutral state.
