LINES GP-FUEL 1514807 - Caterpillar

Introduction
The problem that is identified below does not have a known permanent solution. Until a permanent solution is known, use the solution that is identified below.Problem
Reports have been received that the machine ECM may malfunction intermittently on the machines listed above. This issue occurs due to false diagnostic codes and ECM processor communication issues which prevents successful hydrostatic drive pump and drive motor calibrations, resulting in machine down situation.Solution

(1) The former part number listed is for reference only and may differ.The new 539-3691 Machine Software Gp has the following enhancements:
Implemented feature to determine the idle status of the machine for product link reporting purposes
Added software enabled attachment to allow the install of the optional 8 button switch panel on the machines in the field - Password protected
Added configuration to allow custom brightness setting for the optional 8 button switch panel - Via Electronic Technician (ET)
Updated minimum configurable vehicle speed limit from 20KPH to 15KPH on 906K, 906M, 907K, 907M, 908K and 908M machines
Updated implement valve calibration process to provide improved repeatability of the linkage start to move command on 906K, 906M, 907K, 907M, 908K and 908M machines - Low and high idle cals
Updated machine idle features to provide a smoother transition to higher engine speeds - Slower ramp rate
Updated bucket shake out control to prevent undesired operation - now variable to mode. For example: Fine 60% input required
Updated implement valve calibration process to prevent an operator activating a kick out or float during calibration - float off during cal
Updated rim pull feature to have 3 settings as per hydraulic aggressiveness and hydrostatic aggressiveness
Improvements to control and for calibration on Lesser Regulated Countries (LRC) governors - For 90XK machines only
Improved hydrostatic control and aggressiveness feature to provide improved performance and greater definition between modes
New feature to allow the configuration of the machine hours using ET, the feature allows the machine to be manually or automatically synchronised
Anti-stall now selectable on/off via ET - For 910/914K machines in Highly Regulated Countries (HRC) only
Improved implement control and aggressiveness feature to provide improved performance and greater definition between modes - Including float performance
Improvements to cold weather elevated idle strategy - Lowered activation temperature to reduce unrequired elevated idle
Improved reduced rimpull feature to prevent the operators setting being changed when in high gear on a 90XK/M machines only with a stop to shift transmission
Updated 35kph transmission shift strategy to improve shifting performance by extending the cylinder pressure time by 2 seconds - For 90XK/M machines only
Updated the throttle lock feature to add a configuration that prevents the function disabling when the inching pedal is pressed - For 90XM machines only - Created for OEM machines
Updated the differential lock control strategy to be common across all K/M series Compact Wheel Loaders (CWL). It adds the ability to activate/de-activate with a short press, to configure via ET if a forward to reverse command deactivates the differential lock
Updated float feature
