2017 Blue Bird All American TSBs

sensor replacement parts are not available. This provides a temporary ECM calibration that inhibits engine warning messages for communication errors with the DEF sensor allowing continued operation without engine derate. Regulators are allowing for this temporary calibration to be loaded in the engine ECM by a Cummins authorized repair location if the DEF sensor fails. This temporary calibration does not repair the failure therefore a final repair must be performed and the original calibration be re-installed. Field Service has been requesting an ECM image be uploaded within the support ticket as part of the diagnostics and is carried over into Service Update 2201 (SU2201). In order to receive an authorization code and utilize Cummins TRP2484, you must follow the process, as outlined in SU2201. The specific component affected is Assembly Code: 35-300 Emissions Components.

update improvement to reduce occurrence of Engine fault codes 3555 and 3556 on Cummins diesel engines with the following base ECM calibrations, "HC80145 thru HC80250 and HB80104 thru HC80195"

to include additional new fault codes for all applicable system types (brake, engine, and transmission). Also, "Powertrain, Ford" has been added to the drop-down tab as a system type selection. "Powertrain Ford" system type is used to identify both Ford engine and transmission fault codes.

Also listed is a new Ametek gateway module and applicable software. New Ametek gateway module is only applicable to the Ford Gasoline Vision. Revisions have been made to Ametek instrument cluster software that improve or addresses items noted below. Improved fuel level dampening (only affects diesel fuel systems) Average fuel economy not displaying accurately (only affects diesel fuel systems) High or fast idle set up process on service part replacements (only affects service mode set up) Park brake indicator flashes and audible beep sounds when multiplex module goes in sleep mode (only affects certain Actia to Ametek service part replacements)

To correct this it is necessary to replace both existing rear axle flange gaskets with new gaskets.

These codes indicate either a problem with the aftertreatment battery power/ground circuits, the proprietary data link circuits, or one of the components connected to the proprietary data link. Both Cummins and Blue Bird harnesses include the proprietary data link circuits, and power/ground circuits. Blue Bird harnesses include the aftertreatment powerground circuits, and the proprietary data link circuits on the OEM side of the 14-pin crossover connector that plugs to the Cummins engine harness. The Blue Bird supplied circuits go from the 14 pin OEM crossover connector to the SCR sensor table, DPF sensor table, and the DEF tank sensor. Proprietary data link circuits DO NOT go the the diagnostic port connector located inside the cab of the bus.

Regeneration Inhibit Vehicle Speed Threshold parameter value to 0 mph. Affected Units: All 2017-2020 model year Blue Bird All American School Buses with Cummins ISL-13 or L9 engines manufactured from January 20, 2016 through September 18, 2018 and all model year 2017 through 2020 Blue Bird All American Non-School Buses with Cummins ISL-13 or L9 engines manufactured from January 29, 2016 through September 7, 2018. On the subject buses, Blue Bird or Cummins Dealer is to use the Cummins INSITE electronic service diagnostic program to set the Regeneration Inhibit Vehicle Speed Threshold parameter value to 0 mph. Repair Parts: None Time Allowance: Time allowed to use the Cummins INSITE set the Regeneration Inhibit Vehicle Speed Threshold parameter value to 0 mph in each bus is 0.5 hours. Completion Notification: If you have an authorized Cummins Dealer perform this service bulletin, please notify your Blue Bird Dealer, when the repair is completed. Send the body number, repair date, and odometer reading to your Blue Bird Dealer. If you request reimbursement for labor, also send a copy of the work order/invoice to your Blue Bird Dealer.

School Buses manufactured from November 15, 2013 through August 3, 2016 and certain model year 2015-2017 Vision and All American Non-School Buses manufactured from July 20, 2014 through May 21, 2016 equipped with optional Air Disc Brakes will require replacement of both existing rear axle shaft flange gasket with a new gasket. The new rear axle shaft flange gasket reduces the possibility for oil leaking between the axle shaft and hub. Note: Service Bulletin Campaign S16YU replaces S16YN.

Service Memorandum updates the model year range, engine models affected, and includes Tank Assembly information.

Bird Visions and All Americans School and Non-School units equipped with optional Air Disc Brakes manufactured from November 15, 2013, through February 17, 2016, will require replacement of the existing rear axle flange nuts with a new non-locking nut and star washer. The new rear axle shaft nuts reduces the possibility for oil leaking between the axle shaft and hub.

school and non-school buses manufactured from June 5, 2010 through December 8, 2015, and equipped with optional Cummins diesel engines may experience failure of the 5.50? rear engine exhaust support cables. Instructions are provided for Service Bulletin S16YJ, Rear Engine Exhaust Cables.

manufactured from February 11, 2016, through August 22, 2016, and one model year 2017 All American Non- School Bus manufactured May 23, 2016, equipped with optional Coated Fuel Tanks will require the coating to be removed from the Certification label on the bottom of the fuel tank. On the subject buses, the Certification label on the bottom of the fuel tank may be covered by an applied coating. To correct, coating must be removed from the label.

optional Side Emergency Doors manufactured from October 21, 2014, through July 14, 2016, will require inspection of the heater pipe installation at the side emergency door.

Floor covering material may not be trimmed properly forcing heater pipe to be too high.

Emergency Doors manufactured from February 26, 2015 - May 4, 2016, will require inspection of the heater pipe installation at the side emergency door. On the subject buses, the floor covering material may not be trimmed properly forcing the heater pipe to be too high raising the temperature of the heater pipe cover. To correct this it is necessary to inspect for proper installation and trim the rubber floor covering, if needed. Time allowed for inspection and correction in each bus is 0.5 hours.

and Non- School Buses equipped with optional Side Emergency Doors manufactured from October 21, 2014, through July 14, 2016, will require inspection of the heater pipe installation at the side emergency door.

Additionally, the wiring harness (PN 10023917) connected to the relay base should be inspected for any sign of damage and replaced, if necessary. Blue Bird will provide parts at no cost and will reimburse the repair time in accordance with the information presented below. Affected Units: This service bulletin includes: Certain model year 2015-2021 Vision School Buses manufactured from August 5, 2014 through September 11, 2019.

information for buses equipped with new Diesel Exhaust Fluid (DEF) tank assemblies. Blue Bird buses equipped with new (DEF) tank assemblies have a Gen 5 Tri-Function Sensor. The Gen 5 Tri-Function Sensor provides the level, concentration, and temperature of the (DEF) Diesel Exhaust Fluid in the reservoir and returns a defined CAN message for these values. The sensor and controller communicates on a ?Private? J1939 data link with the Cummins ECM.

service of the Blue Bird products. These troubleshooting guides are available on the Vantage website.

The new cluster will be in full production beginning June 5, 2017. During the time between now and June 5, 2017 Blue Bird will be building some pilot units with the new cluster. Until full implementation Feature 40280 -14 will be added to pilot units. The new Ametek instrument clusters will also be used as a direct service part replacement for older Actia instrument clusters.
