In order to determine whether a specific vehicle has had this Service Action completed or is affected by this Service Action, first check the B-pillar
label for code number 548. If code number 548 has been punched out, the campaign has already been performed. If code number 549 has not been
punched out, it will be necessary to utilize the "Service Menu" of DCSnet (Dealer Communication System) or the Key Reader. Based on the
response of the system, either proceed with the corrective action or take no further action.
