Electronic compass location The electronic compass, also known as the compass module, is mounted on a bracket, which is clipped into the combination bracket frame.
Electronic compass task The electronic compass is used to measure the direction of the near-earth magnetic field and thus determines the heading direction of travel. Only 8 typical cardinal points (N, NW, W, SW, S, SO, O, NO) are shown in the multifunction display (A1p13).
Electronic compass design
  • Magnetic field sensor for measuring alignment of near-earth magnetic field
  • EPROM memory for continual storage of given calibration data and settings
Electronic compass function
  • Transmission of direction information as from active CAN-B
  • Compensation of spurious magnetic fields such as, e.g. heated seat
  • DIAGNOSABLE
  • Performance of self-test, when ignition switched on
