Customer Concern

The dealer must choose which failure code to use depending on if this is a Rapid Service Update
(RSU) or Technical Service Bulletin.
● 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.
● If the customer’s concern matches the SYMPTOM/CONDITION identified in the Technical Service Bulletin,
failure code CC is to be used. When utilizing this failure code, the 3C’s must be supplied.
