Description of Change: New G3500B engine ECM software is now being used. This new engine ECM software has the following enhancement that improves the performance of the previously released engine ECM software.
Two new diagnostics have been added to aid in throttle and bypass actuator troubleshooting. Refer to Table 1.
Table 1
New Diagnostics    
1440-12     Throttle Internal Failure    
1720-12     Bypass Internal Failure    Both of the diagnostics shown in Table 1 indicate that an internal failure of the actuator has occurred, and that the unit requires replacing.Adaptable To: The new G3500B Production Software supports the new 256-7635 Engine Electronic Control Group (ADEM III-16 8kHz ECM) and is backward compatible with 209-5500 Engine Electronic Control Group (ADEM III-16 8kHz ECM) and 151-4790 Engine Electronic Control Group (ADEM III-16 ECM's used on G3500B product).A list of the new G3500B Production Software Part Numbers is provided in Table 2. Note: Installing the new G3500B Production Software is NOT considered warranty repair.
