SPRING LOCK FUEL LINE COUPLING MAY NOT BE PROPERLY ENGAGED.
THE IGNITION LOCK CYLINDER MAY HANG UP AND NOT FULLY RETURN TO THE "ON" POSITION FROM THE "START" POSITION AFTER STARTING THE ENGINE. IF THIS OCCURS, THE ENGINE WILL REMAIN RUNNING, BUT THE BATTERY CURRENT TO THE BRAKE SYSTEM SUPPLY MOTOR WILL BE INTERRUPTED. CONSEQUENCE OF DEFECT: WITH POWER TO MOST ACCESSORIES AND THE BRAKE SYSTEM SUPPLY MOTOR INTERRUPTED, THE POWER ASSIST TO THE FRONT BRAKE WILL BE LOST AND AFTER ABOUT 10 TO 15 NORMAL BRAKE STOPS, LOSS OF REAR BRAKE FUNCTION WILL RESULT, CAUSING INCREASED STOPPING DISTANCE. HOWEVER, THE INSTRUMENT BRAKE WARNING LIGHT WILL ILLUMINATE PRIOR TO REDUCED BRAKING CAPABILITY AND IF WARNING IS NOT HEEDED, AN ACCIDENT MAY OCCUR.
UNDER CERTAIN CONDITIONS, CONTACTS IN BRAKE SYSTEM RELAY COULD REMAIN CLOSED, CAUSING THE BRAKE PUMP MOTOR TO RUN CONTINUOUSLY, CAUSING IT TO OVERHEAT AND EVENTUALLY FAIL. CONSEQUENCE OF DEFECT: SHOULD THE BRAKE SUPPLY MOTOR FAIL, THE POWER ASSIST TO THE FRONT BRAKES WILL BE LOST, AND AFTER ABOUT 10 TO 15 NORMAL BRAKE STOPS, LOSS OF REAR BRAKE FUNCTION WILL RESULT, CAUSING INCREASED STOPPING DISTANCE. HOWEVER, THE INSTRUMENT BRAKE WARNING LIGHT WILL ILLUMINATE PRIOR TO REDUCED BRAKING CAPABILITY AND IF WARNING IS NOT HEEDED, AN ACCIDENT MAY OCCUR.
WIRING CONNECTIONS IN AN ELECTRICAL CONNECTOR TO THE MASTER CYLINDER RESERVOIR FLUID LEVEL SENSORS WERE REVERSED AND FAIL TO INDICATE LOW FLUID LEVELS AS SPECIFIED BY FMVSS 105, HYDRAULIC BRAKE SYSTEMS. CONSEQUENCE OF DEFECT: SENSOR WILL NOT TRANSMIT SIGNAL TO BRAKE WARNING LIGHT WHEN THE FLUID LEVEL IS LESS THAN ONE FOURTH FULL. WITHOUT THIS WARNING SIGNAL THE FLUID LEVEL MAY DECREASE TO THE POINT WHERE PARTIAL OR COMPLETE LOSS OF BRAKE WOULD BE EXPERIENCED AND MAY LEAD TO AN ACCIDENT.
AN ALUMINUM CASTING FLASH ON THE FACE OF THE THROTTLE BODY MAY BREAK OFF AND BECOME TRAPPED BETWEEN THE THROTTLE PLATE AND THE BORE IN THE THROTTLE BODY. CONSEQUENCES OF DEFECT: THROTTLE MAY FAIL TO RETURN TO IDLE POSITION WHEN RELEASED AND COULD RESULT IN LOSS OF VEHICLE CONTROL WHICH MAY CAUSE AN ACCIDENT.
