B1B94-PASSENGER SEAT TRACK POSITION SENSOR CIRCUIT HIGH





For a complete wiring diagram Refer to Section 8W.


  • When Monitored:

    While the CAN bus ignition status is in IGN_RUN and the module is configured for a Passenger Seat Track Position Sensor, the module checks the sensor input current ranges.

  • Set Condition:

    If the module detects that the sensor input is greater than or equal to 20.5 mA. This DTC may set when the current is between 17 mA and 20.5 mA.
