Service Tool Requirement - Cat® Electronic Technician (ET) 2015C or later required for this software releaseNew Features
Selective Catalyst Reduction (SCR) Inducement Emergency Override
In case of 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.Eliminate Key Off Cycle -7 Code False Trip
Issue
The -7 code is not persistent active during key cycle.Resolution
Make the injector not responding code persistent active over key cycle for better troubleshooting.Change -7 Code Tripping Thresholds
Issue
The -7 code is tripped excessively and the -7 code causes dealers to replace injectors when this error code is found.Resolution
Improved sensitivity to the -7 code to reduce false trip and unnecessary injector changes.-499 Code False Trip
Issue
The -499 code is false tripping. This drives replacement of the high-pressure pump. The high volume of returned pumps is showing no fault found.Resolution
Changed the sensitivity and severity of diagnostic code E499 to eliminate false trips.Channel 1 Video (QR Code And Link)

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.SPN 7502 Support for Mid Range (MR)
Issue
No Aftertreatment requested engine speed available in Mid Range Engines.Resolution
Aftertreatment Engine Speed request has been added to align with the Heavy Duty (HD) StrategyActive 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 conditi
