Signal Specification

Connecting the breakout box and checking the ground terminals 

Before taking readings, the breakout box and ground terminal must be checked.

see CHECKING THE VOLTAGE / GROUND TERMINAL

U= DC voltage in volts (V) UAC = AC voltage in volts (V)
Ubat = Battery voltage (V) f = Frequency in Hertz (Hz)
Ulow = Voltage approximately 0 V t = Time in seconds

  #A2 Motor 1+ U = Ulow / U = Ubat U = Ulow / U = Ubat Regulates the front-rear adjustment of the seat.
  #A3 Motor 2+ U = Ulow / U = Ubat U = Ulow / U = Ubat Regulates the backrest rake.
  #A4 Motor 3+ U = Ulow / U = Ubat U = Ulow / U = Ubat Regulates the height of the seat.
  #A5 Motor 4+ U = Ulow / U = Ubat U = Ulow / U = Ubat Regulates the angle of the front edge of the seat.
