and the claim comments (For example: B72 01 21 WP 1), unless otherwise required by State law.
Programming and Encoding – Vehicle Control Units (RO and Claim Comments Required)
This procedure automatically reprograms and encodes any vehicle control modules that do not have the
latest software I-level.
If one or more control modules fail during the reprogramming procedure, claim the required consequential
repair work procedures to address this issue (including performing the IRAP Control Unit Recovery first as
required, refer to the SIB in AIR) under the Defect Code in this bulletin with the labor operations in AIR that
apply.
Please explain the additional work procedures that were performed (The why and the what) on the repair
order and in the claim comments.
For covered repairs that address control module failures that occurred prior to performing this
reprogramming procedure, claim this work with the Defect Code and labor operations (including diagnosis)
in AIR that apply.
Based on which one applies to your center, please refer to SI B01 01 20 or B01 07 20 for the applicable
procedure for documenting, claiming, and explaining, on the RO and in the claim comments, your diagnosis
work time (WT), job/repair work time (WT), and the vehicle repairs your center performed, unless otherwise
required by State law.
Reimbursement of Prior Customer-Pay Repairs (TREAD Act)
Based on the issue and the age of the Affected Vehicles being addressed by this Safety Recall Campaign, a
reimbursement request for a qualifying prior customer-pay repair is not likely.
However, if you receive a reimbursement request from a customer for a prior repair that may qualify, please
contact the Warranty department (include a legible copy of the invoice) through IDS by selecting Coverage,
Policy, Coding Questions and Mileage Corrections. The Warranty department will review and respond to
your inquiry accordingly.

of recall parts.
We appreciate all your assistance with this Recall.
