During the same workshop visit, if a vehicle also requires another Technical Campaign or repair that
also includes programming and encoding the control units, the programming procedure may only
be invoiced one time.
Programming and Encoding - Vehicle Control Units (RO and Claim Comments Required)
A. The programming procedure automatically reprograms and encodes all vehicle control modules
which do not have the latest software I-level. If one or more control module failures occur “during” this
programming procedure:
Please claim this “consequential” control module-related repair work under the defect code listed in
this bulletin with the applicable AIR labor operations.
Please explain this additional work (The why and what) on the repair order in the claim comments section.
B. For control module failures that occurred “prior” to performing this programming procedure:
When “covered” under an applicable limited warranty, claim this control module-related repair
work using the applicable defect code and labor operations (including diagnosis) in AIR.
