FUEL INJECTION SYSTEM RECONFIGURATION TO COMPLY WITH ENGINE EMISSION STANDARDS CAUSE HIGHER ENGINE VIBRATION LEVELS WHICH LEAD TO EARLY WEAR AND COMPLETE FAILURE OF THE SECONDARY THROTTLE RETURN MECHANISM.
Consequence & remedy
Consequence: IN THE EVENT THE PRIMARY THROTTLE RETURN FAILS, FAILURE OF THE SECONDARY THROTTLE RETURN SYSTEM WOULD NOT PROVIDE PROTECTION AGAINST LOSS OF THROTTLE CONTROL.
Remedy: A NEW PRODUCTION SECONDARY THROTTLE RETURN SYSTEM CONFIGURATION WILL BE INSTALLED.
A TOLERANCE MISMATCH IN THE CRANK ASSEMBLY OF THE BOSCH WINDSHIELD WIPER MOTOR COULD CAUSE INSTANTANEOUS SEPARATION OF THE CRANK FROM THE LINKAGE ASSEMBLY IN THE LEFT HAND CONTROL ARM ASSEMBLY; THIS WOULD MAKE THE SYSTEM INOPERABLE.
Consequence & remedy
Consequence: WIPER FAILURE DURING VEHICLE OPERATION COULD REDUCE DRIVER'S ABILITY TO SEE THE ROAD, AND CREATES A POTENTIAL FOR AN ACCIDENT.
Remedy: REPLACE LEFT HAND CONTROL ARM LINKAGE ASSEMBLY.
