ACTION REQUIRED
Before completing this work, please review the safety actions in the Operation and Maintenance Manual for the engine. Please choose one of the following actions: 1. If turbocharger has not failed, reflash the engine ECM with the new software. The new software holds the engine at a safe speed until oil pressure is detected. 2. If the turbocharger has failed, replace the turbocharger and reflash engine ECM with new software. For instructions on removing and installing the turbocharger, refer to KENR9105, "Turbocharger - Remove - First Stage Turbocharger", and "Turbocharger - Install - First Stage Turbocharger". Note that reflashing the ECM software on some of these engines may require Factory Passwords to complete the installation. This is due to some software being specific to certain OEM machine applications. |
