THOMAS C2 - AMU PARK BRAKE SWITCH, 2007-2008 YEAR MODELS PROBLEM: MY OFFICE RECEIVED REPORTS FROM SCDE MAINTENANCE FACILITIES OF CONTINUED FAILURES WITH THE AIR BRAKE INTERLOCK SYSTEM AIR MANAGEMENT UNIT (AMU). THE FAILURE MODE OF CURRENT CONCERN IS WITH THE PARK BRAKE SWITCH IN THE AMU. THIS FAILURE MODE PREVENTS THE RELEASE OF THE PARK BRAKES. THE SCDE OPERATES 879 OF THESE UNITS. CONCERN: WHEN THIS TYPE OF FAILURE OCCURS, THE DRIVER CAN NO LONGER RELEASE THE PARK BRAKES. SCHOOL BUS DRIVERS ARE TRAINED TO SET THE PARK BRAKES EACH TIME THEY ARE LOADING/UNLOADING STUDENTS. IN MOST CASES THERE IS NO WARNING OR INTERMITTENT FAILURE. FAILURES OF THIS TYPE LEAVE THE BUS AND STUDENTS SITTING IN THE MIDDLE OF THE ROAD CREATING A VERY DANGEROUS SITUATION. THE BUS CAN NOT BE MOVED FROM THE ROADWAY UNTIL A TECHNICIAN IS DISPATCHED TO MANUALLY RELEASE THE PARK BRAKES AND ALLOW THE BUS TO MOVE. THE STUDENTS MUST THEN BE OFF LOADED ONTO A SPARE BUS BEFORE CONTINUING THE ROUTE. BACKGROUND: THE AMU WAS PREVIOUSLY INVOLVED IN SAFETY RECALL FL538 A-B FOR THE BRAKE LIGHT SWITCH MODULE FAILURE. WE ARE NOW EXPERIENCING PROBLEMS W/ FAILURES ON THE PARK BRAKE MODULE. WHEN THIS PROBLEM WAS BROUGHT TO MY ATTENTION, I HAD OUR STAFF PULL INSTALLATION INFORMATION FOR THE PART NUMBERS INVOLVED FROM ALL 45 MAINTENANCE FACILITIES. TO DATE OUR RECORDS INDICATE THAT WE HAVE EXPERIENCED THIS TYPE FAILURE ON 139 BUSES OR 16% OF THE 879 UNITS IN OUR FLEET. THESE UNITS ARE IDENTIFIED IN THE ATTACHED EXCEL FILE.

ODI received a complaint regarding a corroded battery post located behind a service panel near the driver's seat on a 2006 Thomas Built C2 school bus that resulted in a fire on the vehicle.It was determined that like buses built prior to a December 26, 2005 design change which added a flange to the lower edge of the panel were susceptible to water intrusion.The design change was meant to address concerns of loose panels but consequently prevented water ingress and the subject corrosion. Daimler Trucks North America (DTNA) submitted a recall notice on October 18, 2011 involving 3,300 of the estimated 6,139 vehicles subject to this investigation.In subsequent communication with ODI, DTNA explained that nearly two thirds of 4,773 MY2007 vehicles were built with the December 26 design change and therefore do not contain the safety related defect.DTNA's announcement of a safety recall on this matter, and subsequent explanation of the scope of vehicles involved, addresses ODI's concerns.The 573 letter was received prior to the due date of the IR response, therefore DTNA has been relieved from having to submit an IR response.DTNA will inspect, clean, repair and protect power cables as needed.The subject vehicles have been recalled and this investigation is closed.The ODI report cited above can be reviewed at www-odi.nhtsa.dot.gov/owners/SearchNHTSAID under the following identification (ODI) number: 10395455

PE11032 · Brake Line Chafing
Opened Sep 12, 2011 · Closed Jan 30, 2012
Status: closed (inferred from source dates) · Service Brakes, Hydraulic:foundation Components:hoses, Lines/piping, And Fittings
The Office of Defects Investigation (ODI) received a complaint alleging brake fluid loss caused by a ruptured brake line that had chafed against a wire harness in the engine compartment of the complainant?s vehicle.It was determined that the chafing was caused by contact between the convoluted tubing covering the fuel supply line and the metal brake lines.This issue only affects units with a Caterpillar (CAT) C7 engine and a fuel water separator mounted in a specific location on the frame rail.Not all units with CAT engines were equipped with fuel water separators, but all units with CAT engines and a fuel water separator have them mounted in the same location.Units with other engines have a different fuel supply line routing and are not affected by this defect.Daimler Trucks North America (DTNA) submitted a recall notice on 18 October 2011 involving seven-hundred (700) model year (MY) 2005-2009 vehicles.In its notice, DTNA provided an explanation that MY2010 vehicles were not built with CAT C7 engines and, that of the model years that were built with C7 engines, only 700 had fuel water separators.All 700 such vehicles are included in this recall.DTNA's announcement of a safety recall addresses ODI's concerns.The recall remedy involves replacement of any damaged brake lines and rerouting as needed.This investigation is closed.The ODI report cited above can be reviewed at www-odi.nhtsa.dot.gov/owners/SearchNHTSAID under the following identification (ODI) number: 10383939
