Service Tool Requirement - Cat® Electronic Technician (ET) 2015C or later required for this software release.New Features
Selective Catalyst Reduction (SCR) Inducement Emergency Override
If there is emergency situations, the EPA allows the override of SCR Inducements. This feature can be enabled through Cat ET service Tool. once enabled (factory password required), this feature provides 120 hours of inducement free operation. The override timer can be activated with either a physical switch (J1–22 on A5E2) or Cat ET service tool.Caterpillar Regeneration System (CRS) Lean Burn Strategy
Lean burn strategy has been added to startup mode (SM) and maintenance timer (MTB) regens. This reduces the potential of regen issues related to a sooted up flame temp sensor.Enhancements to Existing Features
Flexxaire Settings
Issue
Operator is unable to adjust purge settings.Resolution
Default Purge Settings changed from 2 hours to 18 hours and duration from 5 seconds to 60 seconds. This setting is configurable in the Cat ET service tool.Selective Catalyst Reduction (SCR) Inducement Faults Snapshot
Issue
The operator is unable to use tool for Troubleshooting.Resolution
Removed the Snapshot support for the SCR inducement faults.Diesel Exhaust Fluid (DEF) Quality Detection
Issue
The DEF quality sensor is unable to detect degraded concentration under certain conditions.Resolution
The timer was changed to meet the sampling requirements.Active Regeneration Device (ARD) Nozzle Heater Diagnostic
Issue
Code 3182-4 Aftertreatment #1 Fuel Injector #1 Heater : Voltage Below Normal clears on key cycle and does not remain an active diagnostic for Troubleshooting issue.Resolution
Changed the code to be persistent active when tripped for better Troubleshooting.Fixes
Diesel Exhaust Fluid (DEF) Tank and Coolant Temperature Kick Out
Issue
During the Aftertreatment function test, the test immediately aborts if conditions are not met.Resolution
Changed initiate requirements to allow preconditions of coolant temperature to be met then DEF conditions. If DEF conditions are not meet, the Aftertreatment function test will abort.Cooling System Capacity Test
Issue
The EGR Gas MASS Flow is unavailable in the Cooling System Capacity Test forcing technician to abort test to view EGR Gas MASS Flow.Resolution
Added Exhaust Gas Mass Flow Rate status parameter to Cooling System Capacity TestCaterpillar Regeneration System (CRS) Nozzle Heater
Issue
The CRS nozzle heater shorten cycle was causing heater nozzle plugging.Resolution
CRS nozzle heater timer resets and timer durations have been updated to correct this issue.Post Regen Main Fuel Spritz
Issue
A popping sound is noticed during the post regeneration main fuel spritz.Resolution
Spark has been disabled during the main fuel spritz action.Maintenance Timer (MTB)
Issue
Forced MTB regens with the auto regen capability disabled on applications are unable to reset the regen trigger request. This is leading subsequent regen requests without the trigger getting reset. This can lead to operator confusion in the field.Resolution
Logic was updated to go from MTB to Non-MTB at the end of the regen. This will allow the reset.Low Battery Voltage Diagnostic
Issue
False trip battery diagnostic during operator forced shutdown. This creates derate without active fault code.Resolution
Robustness of diagnostic was improved to reduce false tripping and derate issue.DPF #1 Intake Pressure Sensor Out of Calibration
Issue
False trip code 3464-13 under cold ambient temperature.Resolution
Changed the minimum DPF inlet temperature condition set point for DPF Intake Pressure Sensor Code 3464-13.SCR Inducement DEF Control Unit Faults
Issue
DCU faults were considered tampering faults which caused downtime and loss of productivity.Resolution
DCU faults have been categories into tampering and non-tampering. This new change will trigge
