B2117 ADJ PEDAL MOTOR
B2117 ADJ PEDAL MOTOR
Description
INFOID:0000000006163473
• The pedal adjusting sensor is installed to pedal adjusting motor assembly.
• The resistance of pedal adjusting sensor is changed according to the forward/backward position of pedal
assembly.
• The terminal voltage of automatic drive positioner control unit will be changed according to a change of
pedal adjusting sensor resistance. Automatic drive positioner control unit calculates the pedal position from
the voltage.
