In order to allow equitable parts availability to all participating dealers, please limit your initial parts order to not exceed 45% of dealership population. This is an initial order recommendation only, and the ultimate responsibility for ordering the total number of parts needed to satisfy the program lies with the dealer.
ACTION REQUIRED
New engine software needs to be installed to correct the issue. A parameter called "Fuel Enable Input" has been added in ET Configuration screen under Configuration Group 1. Setting this parameter to "ON" will allow the Engine ECM to look for the CAN Fuel Disable signal from EMCP panel. Functionality of the Stop button on the EMCP will be restored.
Refer to the Service Manual if/as necessary and follow these steps:
A. Flash engine ECM with the new engine software that is applicable to the engine serial number being serviced.
Note: Always use the latest software available. Sometimes the flash file part numbers are updated before the program terminates.
B. Engines equipment with EMCP Panels - Turn on Fuel Enable Input parameter in configuration screen using CAT ET, please reference image 1.
Note: If you do not turn on the Fuel Enable Input in ET, engine will not shutdown using the EMCP Stop Button.
C. No changes are required in the EMCP configuration.
D. Vessel wiring may also need to be reworked. If vessel wiring is incorrect with new software the engine will not start.
E. If the vessel equipment was using Fuel Enable Input in the previous engine software version, you will need to turn on the Fuel Enable Input in ET Configuration (reference image 1) after flashing new software.
Note: Engine may not shutdown when requested to do so by the vessel equipment if Fuel
