(1) All languages excluding Chinese and Japanese
(2) English and Chinese
(3) English and JapaneseEnhancement of Transmission/Chassis Software
New 522-9045 Power Train Software Gp replaces the former 521-2516 Power Train Software Gp.
Added Histograms for Axle oil temperature on C2 machines.Note: Center Axle Temperature Histogram requires ET 2017A or higher to view, ET 2017A release date Tuesday 14th February 2017
Added elevated (800rpm) idle during brake charging events (735C machines only).
Added cycle segmentation feature which improves payload function when installed.
Improved park brake switch fault tolerance and improved fault state reporting for service brake switch.
Updated Brake Oil Filter Monitoring enablement temperature from 10° to 40°C (50° to 104°F). This will ensure the ECM does not monitor for a brake oil bypass until the brake oil is sufficiently warm and has exceeded 40° C (104° F).
Resolved issue with lifetime operating hours not working with ECM replacement feature.
Improved switch responsiveness of Waiting Brake button.
Added support for coasting in neutral event.
Improved diagnostic support for transmission intermediate speed sensors.
Improved transmission clutch control and shift control logic to provide better interrupted shift protection.
Improved transmission calibration and service test thresholds for robustness.Enhancement of Chassis Software
New 521-3629 Machine Software Gp replaces the former 502-0885 Machine Software Gp.
Improved engine oil level monitoring feature to reduce risk of false occurrences of EID 171-1 with multiple successive engine starts.
Improved inertial measurement unit fault handling to reduce false occurrences of EID 4320-2 and EID 4321-2.
Improved traction control performance in soft underfoot conditions.
Improved Traction Control behavior in the event that the rear IMU is faulted.
Added "Automatic Traction Control Slip Reduction Aggressiveness" configuration within Electronic Technician. This is defaulted to “Low”. “High” should only be used with supporting hardware which will be available in 2017; making it active without the hardware may provoke additional diagnostics error codes.
Updated Traction Control behavior when stopped on a grade to reduce risk of low brake pressure warnings.Enhancements for following machine events and diagnostics
