Problem Description
Bendix has determined that a component manufactured at a Bendix sub-supplier was not within specification
limits, leading to the potential defect. The defect is an undersized hole in the non-adjustable brake pedal that may

Dear Glen R. Braly Jr. :
IMPORTANT RECALL INFORMATION – RESPOND IMMEDIATELY
This is to inform you that Bendix Commercial Vehicle Systems LLC (Bendix) notified the National Highway
Traffic Safety Administration (NHTSA) of the start of a voluntary safety recall campaign involving the Bendix®
Brake Switch Interface within select Bendix Driver Control Module (DCM)s. The recall has been assigned number
22E033.
A copy of our April 13, 2022, Defect and Noncompliance Information Report submission to NHTSA can be found
on the NHTSA website (https://www.nhtsa.gov/recalls) under recall number 22E033. As required by law, Bendix
informed NHTSA that Blue Bird is the only vehicle manufacturer customer to whom Bendix sold the affected
products outright.
IMPACTED PRODUCT
This recall includes the brake pedal contained within all Bendix Driver Control Modules (DCM) produced for
Blue Bird C-Chassis with hydraulic brakes, a Cummins® engine, and a non-adjustable pedal – brake pedal part
number K025587 | Blue Bird DCM part numbers 10049991 and 10049992 – manufactured between May 1, 2021,
and March 16, 2022. This action does not affect DCMs manufactured prior to or after the stated dates, nor those
manufactured for any other OEM.
Affected DCMs are identifiable solely by the presence of a serialized, Bendix-generated identification label.
Bendix will provide a list of the affected serial numbers under separate cover.
PROBLEM DESCRIPTION
Bendix has determined that a component manufactured at a Bendix sub-supplier was not within specification
limits and has led to the potential defect – an undersized hole in the brake pedal that may not allow for proper
movement of the brake light switch interface components. The interface between the brake pedal and the brake
light switch may bind and not change states, leading to improper brake light operation. Brake lights may not come
on when the brake lights are applied, or brake lights may remain illuminated when the brakes are not applied. The
binding condition and the associated malfunction may be intermittent.
2
WHAT WE WILL DO
Bendix Commercial Vehicle Systems LLC (Bendix) will voluntarily remedy the defect within the DCM with
the impacted brake pedal, with a kit of parts that do not have the potential defect. As a reminder, the kit will
be provided to you free of charge. The installation labor charge to complete the remedy will be covered by Bendix.
WHAT YOU NEED TO DO
First, we are providing you with this information to enable your business to determine whether there is a safetyrelated
defect on your vehicles where the affected brake pedal within the Driver Control Module (DCM) has been
installed.
Based on your determination, you may need to file a Defect and Noncompliance Report to the National
Highway Traffic Safety Administration (NHTSA) with respect to new motor vehicles with an affected
Bendix DCM sold in the United States. A similar notification may be required to Transport Canada for all
impacted vehicles sold in Canada.
Our records indicate that Blue Bird purchased the following suspect DCMs from Bendix:
Bendix OE Part Number Quantity
10049991 806
10049992 29
We value our business relationship with you. We regret the inconvenience that may result from these
circumstances, and we sincerely appreciate your understanding and cooperation in this matter. If you have any
questions or require more information, please do not hesitate to reach out to your Bendix Account Manager
directly. You may also contact us via email at BBSwitch22@bendix.com, or by telephone – toll-free – at
1-800-AIR-BRAKE (1-800-247-2725), option 2. Bendix Tech Team representatives are ready to assist you
