Consequence

INSUFFICIENT TIGHTENING PERMITS MOVEMENT BETWEEN THE COMPONENTS THAT COULD RESULT IN BOLTS AND STUDS BREAKING, INCREASING THE RISK OF A CRASH.

Remedy

DEALERS WILL REPLACE THE 5/8" GRADE 8-HANGER BOLTS. IN ADDITION, AXLE SPRING SEAT FASTENERS WILL BE CHECKED FOR PROPER TIGHTNESS AND, IF NEEDED, TIGHTENED TO SPECIFICATIONS. OWNER NOTIFICATION BEGAN JANUARY 18, 2002.

Consequence

THIS CONDITION CAN RESULT IN POWER FAILURE AND/OR RISK OF FIRE IN THE ENGINE COMPARTMENT.

Remedy

Defect

VEHICLE DESCRIPTION: TRANSIT AND SCHOOL BUSES EQUIPPED WITH MERITOR WABCO PHASE 1, D-VERSION ANTILOCK BRAKE SYSTEM (ABS), FAIL TO COMPLY TO THE REQUIREMENTS OF FMVSS NO. 105, "HYDRAULIC AND ELECTRIC BRAKE SYSTEMS." AN INTERNAL DIAGNOSTIC SYSTEM IN THE ABS MAY NOT DETECT AN EXTREME WHEEL SPEED SENSOR AIR GAP. SUCH A CONDITION COULD POSSIBLY OCCUR DURING (1) ORIGINAL ASSEMBLY OR (2) SUBSEQUENT WHEEL END SERVICE.

Consequence

FAILURE OF THE ELECTRONIC CONTROL UNIT TO DETECT AN EXTREME WHEEL SPEED SENSOR AIR GAP CAN RESULT IN THE LOSS OF ANTILOCK BRAKING FUNCTION ON THE WHEEL(S) WHERE THE AIR GAP EXISTS, INCREASING THE RISK OF A CRASH.

Remedy

THE ABS ECU WILL BE REMOVED AND REPLACED OR THE ECU WILL BE REPROGRAMMED.

Defect

VEHICLE DESCRIPTION: SCHOOL AND TRANSIT BUSES EQUIPPED WITH ELECTRONIC ENGINES AND FELSTED ELECTRONIC ACCELERATOR PEDALS. THE RETURN SPRINGS CAN BREAK ON THE ACCELERATOR PEDALS THAT ARE EQUIPPED WITH STAINLESS STEEL OR ELECTROPLATED MUSIC WIRE RETURN SPRINGS.

Consequence

THIS CONDITION COULD CAUSE THE PEDAL TO GO TO FULL THROTTLE IF BOTH RETURN SPRINGS BREAK, INCREASING THE RISK OF A CRASH.

Remedy

REPLACEMENT ACCELERATOR PEDALS EQUIPPED WITH RETURN SPRINGS MANUFACTURED OF MUSIC WIRE WITH ONE ADDITIONAL COIL ON EACH SPRING AND WITH AN ORGANIC COATING, ELIMINATING ELECTROPLATING WILL BE INSTALLED.

Defect

VEHICLE DESCRIPTION: SCHOOL AND TRANSIT BUSES EQUIPPED WITH BENDIX AIR BRAKES. BENDIX CHANGED THE INTERNAL DESIGN OF THE QR1C RELAY VALVE BY ADDING A HOLE IN THE INTERNAL DIAPHRAGM. WHEN THE HOLE IN THE DIAPHRAGM ALIGNS WITH THE HOLE IN THE VALVE BODY, THE BRAKE APPLICATION TIME INCREASES.

Consequence

UNDER CERTAIN CONDITIONS, SUCH AS PARKED ON AN INCLINE, DRIVER ACTIVATES THE PARKING BRAKE BUT REMOVES FOOT FROM THE THREADLE VALVE, THE BUS COULD ROLL BEFORE THE PARKING BRAKE IS FULLY ENGAGED.

Remedy

DEALERS WILL REPLACE THE DIAPHRAGMS WITH HOLES WITH SOLID DIAPHRAGMS FOR THE QR1C VALVES.

Defect

VEHICLE DESCRIPTION: SCHOOL BUSES EQUIPPED WITH TRANSIT SLIDING PUSHOUT WINDOWS. POTENTIAL STICKING AND/OR BINDING OF THE PUSHOUT WINDOW INNER FRAME WITHIN THE OUTER FRAME RESULTS IN OPENING FORCES EXCEEDING THE REQUIREMENTS OF FMVSS NO. 217, "BUS WINDOW RETENTION AND RELEASE."

Consequence

PERSONAL INJURY COULD OCCUR IN THE EVENT OF A CRASH.

Remedy

OWNERS WILL BE PROVIDED WITH STEP-BY-STEP PROCEDURES FOR MODIFYING THE TRANSIT SLIDING PUSHOUT WINDOWS TO CONFORM THE FMVSS 217 REQUIREMENTS.

Defect

VEHICLE DESCRIPTION: SCHOOL AND TRANSIT BUSES EQUIPPED WITH BENDIX ABS ANTI-LOCK BRAKING SYSTEM. THE PRIMARY AND SECONDARY BRAKE TREADLE VALVE AIR LINES WERE INSTALLED INCORRECTLY AT THE BENDIX R12DC RELAY VALVE.

Consequence

WITH THE BRAKE SYSTEM INSTALLED INCORRECTLY, FUTURE MAINTENANCE MIGHT BE AFFECTED BY THIS INCONSISTENCY, CAUSING THE BRAKES TO BE INSTALLED INCORRECT, INCREASING THE RISK OF A CRASH.

Remedy

DEALERS WILL CORRECT THE AIR LINE PLUMBING AT THE BENDIX R12DC RELAY VALVE.
