PROBLEM
New power train system software, implement system software, and Messenger software need to be installed on certain 16M 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. -Enhancement of the "Limited Inching" strategy to set the default status to "Enabled". -Improvement to compression brake logic that turns the compression brake off at engine speeds less than 1250 rpm. -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. |
