## What is wrong

FAILURE OF THE BRAKE CONTROL MODULE MAY OCCUR WHEN THE PRIMARY BRAKE BOOSTER SYSTEM IS NOT OPERATING. IF THIS MODULE WERE TO FAIL AND A FAILURE OF THE PRIMARY BRAKE BOOSTER SYSTEM WERE TO OCCUR, THERE WOULD BE A LOSS OF POWER ASSIST TO THE BRAKE SYSTEM WITHOUT WARNING AND STOPPING POWER WOULD BE REDUCED.  A REDUCTION OF BRAKING ABILITY WHEN MINIMUM STOPPING DISTANCE IS REQUIRED COULD RESULT IN A VEHICLE CRASH WITHOUT PRIOR WARNING.
