Electronic Controlled Fuel System C8.3 Industrial Page 1-12 Section 1 - Operating Instructions Engine Shutdown General Information Allow the engine to idle 3 to 5 minutes before shutting it off after a full-load operation. This allows adequate cool down of pistons, cylinders, bearings, and turbocharger components. NOTE: For engines equipped with an electronic control module (ECM) ensure the keyswitch is turned off for a minimum of 70 seconds prior to disconnecting the continuous (unswitched) battery power supply. If the unswitched battery power supply is disconnected in less than 70 seconds after the keyswitch is turned off active fault codes and incorrect ECM information can occur.
Turn the ignition switch to the OFF position. If the engine does not shut down, refer to Troubleshooting Symptom (Section TS) in appropriate Operation and Maintenance manual. Failure to follow the correct shutdown procedure may result in damage to the turbocharger and shorten the turbocharger life. CAUTION Electronic Controlled Fuel System Fault Lamp Sequencing General Information The ENGINE FAULT AND MAINTENANCE lamps are illuminated when the keyswitch is turned to the ON position. After 2 seconds, the red STOP ENGINE lamp will turn off. After an additional 1/2 of a second, the amber CHECK ENGINE lamp will turn off.
After an additional 1/2 of a second, the amber ENGINE MAINT lamp will turn off. The lamps will remain off until a fault is detected. NOTE: This is a self-test feature of the lamp wiring and lamps. NOTE: The names and colors of the lamps can vary with vessel manufacturer if non-Cummins panels are used.
