RETAINER 1078085 - Caterpillar

Use this procedure in order to troubleshoot a failed aftertreatment regeneration or use this procedure if one of the following event codes are active. Refer to Troubleshooting, "Event Codes" for information about event codes. For information on the engine monitoring system, refer to Troubleshooting, "Engine Monitoring System".Active regenerations usually occur during normal engine operation. However, engine operation or operator desire may cause the operator to activate the force regeneration switch. This switch signals the Engine Electronic Control Module (ECM) that a forced regeneration is desired. The engine ECM will determine the status of the engine and the products operating condition and determine if it is okay to begin an active regeneration. The elapsed time is approximately 5 seconds for the engine ECM to determine if the conditions are acceptable for an active regeneration to begin.If conditions allow that an active regeneration may begin, the ECM will illuminate the appropriate indicators and begin the active regeneration. If conditions will not allow an active regeneration to begin, the ECM will illuminate the Action Lamp and annunciate one of the following Diagnostic Trouble Codes (DTCs). The code will appear on the Messenger Display. The code will also be displayed on Cat ET.Note: One forced regeneration per key cycle is permitted if a failure to ignite, insufficient temperature to complete regeneration, or loss of combustion diagnostic trouble code is active. This determines if the regeneration can run and clear the event.
