Stopping the engine immediately after the engine has been working under load can result in overheating of SCR components.Refer to the Operation and Maintenance Manual, "Engine Stopping" procedure to allow the engine to cool and to prevent excessive temperatures in the turbocharger housing and the DEF injector.
Allow the engine to perform a DEF purge of the DEF system before you turn the battery disconnect switch to OFF. Disconnecting the battery power too soon may prevent purging of the DEF lines after the engine is shut down. Refer to this Operation and Maintenance Manual, "Battery Disconnect Switch" for more information.
Warning Strategy
The Electronic Control Module (ECM) will be enabled with a world-wide warning strategy.Warning Indicators
The warning indicators consist of a level gauge for the DEF, a low-level lamp for the DEF, an emission malfunction lamp, and the application stop lamp.

Warning Levels
The SCR has three levels of warning. Depending on the fault that has been detected and software enabled will govern the time that the system will stay at each warning level.Any warning should be investigated immediately, contact your Cat dealer. The system is equipped with an override option. Once the override option has been used and the fault still exist, the engine will be locked in de-rate or shutdown mode.Definitions
Self-correct Fault condition no longer exists. An active fault code will no longer be active.
Notification Action taken by the system to alert the operator of pending Inducement.
Inducement Engine derates, vehicle speed limits, or other actions intended to prompt the operator to repair or maintain the emission control system.
Inducement Categories The Inducements are separated into categories. DEF Levels have inducement fault codes separate from the other inducement categories. DEF level inducements are based on the DEF level, the other inducement categories are based on escalating time. The escalating time inducements will always have an associated fault code along with the inducement fault code. The associated fault is the root cause. The escalating time inducement fault code is just an indicator of what level of inducement the engine is in. The escalating time inducement fault code also indicates how much time remains until the next level of inducement. There are three inducement categories that will trigger an escalating time inducement fault code.Note: The associated codes for each of the escalating time categories can be found in Troubleshooting, SCR Warning System Problem.
First Time When an escalating time inducement fault code becomes active for the first.
Repeat occurrence When any escalating time inducement fault code becomes active again within 40 hours of the first occurrence. Engine must run for 40 hours without tripping any escalating time inducement fault before returning back to first occurrence times.
Safe Harbor Mode (Worldwide) Safe Harbor Mode is a 20 minute engine run time period. Once in level 3 inducement, the operator can perform a key cycle and the engine will enter Safe Harbor Mode. Safe Harbor Mode can only be implemented once. Safe Harbor Mode is not allowed for DEF level inducements with Worldwide configuration.World-Wide SCR Warnings
At Level 1 the emission malfunction lamp will be on solid.
At Level 2 the emission malfunction lamp will flash.
At Level 3 the emission malfunction lamp will flash and the stop lamp will activate.
At Level 3 the engine may shut down, or operate at 1000 Revolutions Per Minute (RPM).
At Level 3 cycling the keyswitch will give 20 minutes override at full power, before the shutdown or idle is triggered. The emission malfunction lamp will continue to flash.World-Wide Reduced Performance Setting
