The new software has various improvements that are listed below.

Turbocharger Monitoring - Added Cat^® Electronic Technician (ET) configurable turbocharger failure detection strategy.

Sensor Diagnostics - Improve sensor diagnostic strategy filters to reduce intermittent tripping of sensor codes leading to a shutdown.

Snapshot Support - Added snapshot feature to improve troubleshooting capability for intermittent issues.

Engine Percentage Load Rounding Fix - Updated the engine percentage load calculation resolution to display the value more accurately for Locomotive applications.

Fuel Consumption and Engine Hours Display Update - Updated total fuel consumption SPN 250 range to prevent calculation from resetting and freezing at 0 L. Updated the engine hours SPN 247 range for similar reason.

Sensor Diagnostic Derate Updates - Nuisance and engine protection diagnostic codes will report a derate and can cause a shutdown.

Pre-lubrication Override Support - Added engine oil pre-lubrication override support to reduce troubleshooting time.
