1986 Lincoln Mark VII Review

Summary: SPRING LOCK FUEL LINE COUPLING MAY NOT BE PROPERLY ENGAGED.

Consequence: COUPLING COULD DISENGAGE DUE TO FUEL PRESSURE,VIBRATION, AND ENGINE MOVEMENTS; THIS WOULD CAUSE LOSS OF FUEL WHICH, INPRESENCE OF AN IGNITION SOURCE, CREATES A FIRE RISK.

Remedy: INSTALL RETAINER CLIPS OVER THE COUPLINGS TO PREVENT COUPLING SEPARATION AND FUEL LEAKAGE.

Notes: SYSTEM: FUEL LINE COUPLINGVEHICLE DESCRIPTION: PASSENGER CARS AND LIGHT TRUCKS EQUIPPED WITH FUELINJECTION.

Summary: 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.

Remedy: REPLACE IGNITION LOCK CYLINDERS WITH REVISED DESIGN CYLINDERS.

Notes: SYSTEM: IGNITION LOCK CYLINDER/BRAKES.VEHICLE DESCRIPTION: PASSENGER CARS EQUIPPED WITH A BRAKE SYSTEM SUPPLY MOTOR FOR HYDRAULIC REAR BRAKES AND POWER ASSIST FRONT BRAKES.

Summary: 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.

Remedy: REPLACE PUMP MOTOR RELAYS.

Summary: 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.

Remedy: RE-CONFIGURE WIRING TO THE FLUID LEVEL SENSOR CONNECTOR.

Notes: SYSTEM: BRAKE FLUID INDICATOR/FMVSS 105.VEHICLE DESCRIPTION: PASSENGER CARS.

Summary: 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.

Remedy: REMOVE EXCESS CASTING FLASH.
