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 and 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.
