There is a new TSB out 24-NA-143 that requires Dealerships to do the above 24-NA-113 whenever an Ultium Vehicle is in for service and before vehicle is delivered to a customer as part of PDI (one time). This replaced an earlier PIT 6065 process that required Dealerships to update all modules of Ultium vehicle while in for service.
