● The “RF” failure code is required for essential module flash/reprogramming and can only be used after
confirmation that the VIN is included on the RSU.
● The failure code “RF” (Required Flash) can no longer be used on Technical Service Bulletin flashes. The
“RF” failure code must be used on an RSU.
