( 1 ) Software is flashed over the airProduct Link Improvements and Enhancements for 523
The following Product Link improvements and enhancements for the 523 are included in the new software.
This update addresses erroneous fuel loss alerts by eliminating the large delta between fuel level data sent by Product Link during a key ON event. Now Product Link sends a more accurate fuel level value during a key ON and key OFF event.Note: To obtain the full benefit of this improvement and all previous improvements, both the radio and the gateway software must be flashed. It is important to submit a field support case to have the Radio flashed over the air after the Gateway software has been downloaded and installed.VIMS Improvements and Enhancements for 523
