OPERATION LOGIC IMPROVEMENT (SA557)
This bulletin provides the procedure to update the software logic of the Power Seat Module (PSM) system on
certain 2024MY EV9 (MV) vehicles produced from September 24, 2023 through November 6, 2023 to improve
the front seat Easy Assist and Leg Rest operation, preventing the driver's leg rest from extending while driving.
In addition, the software also improves the logic of the cargo area power folding seat buttons, so that the left
seat will fold partially if the front row seat is too far back, which is the existing logic for the right seat. Follow
the procedure outlined in this publication to apply the improved logic to the ‘PSM’ system using the KDS ECU
Upgrade function as described in this bulletin. For confirmation that the latest reflash has been applied to a
vehicle you are working on, verify the ROM ID using the table on page 6 of this bulletin.
