In order to allow equitable parts availability to all participating dealers, please limit your initial parts order to not exceed 13% 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.
|
Install the new 491-4356 Software which correctly matches the faults code with the electric schematic.
Refer to M0077736, Special Instruction, "Procedure To Flash Application Files To Certain AP255E Asphalt Pavers", to flash the new software into the ECM.
Note: Always use the latest software available. Sometimes the flash file part numbers are updated before the program terminates. |
