BLUE BIRD BODY COMPANY 3920 Arkwright Road, Suite 200, Macon, GA 31210 – (478) 825-2021 R22BP IMPORTANT SAFETY RECALL NOTICE NHTSA Campaign Number: 22V-049 (School Bus) DATE: March 17, 2022 SUBJECT: R22BP: FMVSS 403 Noncompliance – Wheel Chair Lift Brake Interlock Inoperative Dear Blue Bird Owner: This notice is sent to you in accordance with the requirements of the National Traffic and Motor Vehicle Safety Act. This important safety recall notice applies to your bus(es) identified by both Blue Bird Body Number and Vehicle Identification Number (VIN) on the enclosed yellow cover sheet. If you no longer own the subject bus(es), please complete the appropriate section of the yellow cover sheet and return to Blue Bird in the enclosed pink postage prepaid envelope. Blue Bird Body Company is voluntarily recalling the following:  Certain model year 2023 Blue Bird Vision School Buses o manufactured from December 2, 2021 through December 18, 2021 On the subject buses, it has been determined that certain Blue Bird buses could fail to conform to the Federal Motor Vehicle Safety Standard Number FMVSS 403, Platform Lift Systems. Blue Bird shall conduct a voluntary safety recall to correct this noncompliance. It has been determined that certain Blue Bird Vision (BBCV) School Buses equipped with brake interlock features may fail to conform to the Federal Motor Vehicle Safety Standard FMVSS 403, Platform Lift Systems. During normal interlock operation, a vehicle cluster notification identifies when the interlock is active when the lift is not in the stowed position. With the affected units, the indicator for active interlock would not be present. No additional notification is present other than the absence of the indicator. This is due to an incorrect software file in the vehicle multiplex. The affected units are not sending a signal to activate the brakes, when the wheel chair lift is in use. The root cause of this issue was determined to be an error in the software configuration database. The safety risk is the bus could move while the platform lift is in operation. Unexpected movement could result in increased risk of injury to the user and/or operator of the platform lift. Corrective Action: To correct this noncompliance, Blue Bird will notify the affected dealers and owners and provide repair instructions. Labor Reimbursement: Blue Bird will reimburse the labor cost of repairs relating to this recall at no cost to you the vehicle owner. The Repair Option and allowable labor time for this campaign is outlined below:  R22BP Repair o 0.5 hours (30 minutes) Administering the Recall: Buses with this non-compliance must be corrected immediately. A software update is currently available. The expected out of service time necessary to accomplish the software update is 30 minutes.

This is due to an incorrect software file in the vehicle multiplex. The affected units are not sending a signal to activate the brakes when the wheel chair lift is in use. The root cause of this issue was determined to be an error in the software configuration database. Production Dates : DEC 02, 2021 – DEC 18, 2021 VIN Range 1 : Begin : NR End : NR Not sequential Description of Defect : Description of the Defect : Federal Motor Vehicle Safety Standard FMVSS 403, Platform Lift Systems: This is due to an incorrect software file in the vehicle multiplex. The affected units are not sending a signal to activate the brakes when the wheel chair lift is in use. The root cause of this issue was determined to be an error in the software configuration database. FMVSS 1 : 403 – Platform lift systems FMVSS 2 : NR Description of the Safety Risk : The risk is the bus could move while the platform lift is in operation. Unexpected movement would result in increased risk of injury to the user and/or operator of the platform lift. Description of the Cause : Blue Bird determined the database referenced by configuration software had been incorrectly updated, causing the interlock to not activate according to the FMVSS 403 regulation. Part 573 Safety Recall Report 22V-049 Page 2 The information contained in this report was submitted pursuant to 49 CFR §573 Identification of Any Warning that can Occur : During normal interlock operation, a vehicle cluster notification identifies when the interlock is active when the lift is not in the stowed position. With the affected units, the indicator for active interlock would not be present. No additional notification is present other than the absence of the indicator. Involved Components : Component Name 1 : Vehicle S19 file Component Description : Individual Vehicle Software File (unique to each unit, and stored by Body Number) Component Part Number : N/A Vehicle software file is stored on a dedicated Blue Bird server, available to our dealers. Supplier Identification : Component Manufacturer Name : NR Address : NR NR Country : NR Chronology : In early January, 2022, an issue was raised by the Blue Bird internal quality team about a BBCV unit with an inoperative wheel chair lift brake interlock. The Blue Bird Engineering Team reviewed the affected unit and determined that a new software file was needed and proceeded to correct the unit. The engineering team continued to sample similar units to determine the root cause. It was determined on January 31, 2022, that the software issue was caused by an error in the software configuration database. The database error occurred in the initial product launch on October 1, 2021. Engineering made an update to the database on November 16, 2021, to correct an internal feature definitions issue, at that time it was not known that software compiled before this date would experience an issue with the wheel chair lift brake interlock function. All affected specific units where the vehicle software file was generated between October 1, 2021, and November 16, 2021, were deemed to be suspect. At this time, all affected units that have not yet been delivered have been updated with the correct software. There have been no reports from the field related to this issue. Part 573 Safety Recall Report 22V-049 Page 3 The information contained in this report was submitted pursuant to 49 CFR §573 Description of Remedy : Description of Remedy Program : Blue Bird will provide a software update which can be performed by the owner’s local Dealer or Authorized Service Center. Labor Reimbursement: Blue Bird will reimburse the labor cost of the repair related to this recall at no cost to the Dealer or to the vehicle owner. How Remedy Component Differs from Recalled Component : Remedy component is a lift-equipped vehicle software file that was created and loaded after November 16, 2021. The recall component is a lift-equipped vehicle software file created and loaded between the start of production, October 1, 2021 and November 16, 2021. Identify How/When Recall Condition was Corrected in Production : Engineering made an update to the database on November 16, 2021 to correct an internal feature definitions issue, which inadvertently CORRECTED the issue. Once engineering was able to determine that the initial configuration database that was in place from October 1, 2021 up to the change on November 16, 2021 was the issue, all units that had not shipped were reprocessed with the updated vehicle software file. Recall Schedule : Description of Recall Schedule : Dealer and Owner Notifications are to be issued on or before March 30, 2022. Parts are not required. Planned Dealer Notification Date : MAR 30, 2022 – MAR 30, 2022 Planned Owner Notification Date : MAR 30, 2022 – MAR 30, 2022 * NR – Not Reported
