Code B1987 Ford Description

he Driver Seat Module (DSM) uses a Hall-effect switch attached to the pedal motor to identify the current pedal position. The DSM sends a reference voltage through the Hall-effect switch and back to the DSM along the signal return circuit.
When 1 or more of the following Diagnostic Trouble Code (DTC) is set, the adjustable pedals will enter a jog mode. When the pedals are in jog mode, the memory system recall will not function from either the Remote Keyless Entry (RKE) transmitter or the memory SET switch buttons. When the pedals are actuated using the adjustable pedal switch, the motor will move the pedals for one second in the direction selected regardless of the length of time the button is actually pressed.
This DTC is only set during a DSM on-demand self test. During the self test, the adjustable pedal motor will be commanded to move forward and then rearward. If the motor encounters a hard stop while moving, the DSM will attempt to move the pedals in the opposite direction. If the DSM does not see any pedal movement via the Hall-effect switch during this attempt, DTC B1987 will be set and the adjustable pedal system will be disabled.
