MTU ADEC showed random ECU fault codes. ECU sent 8 bytes of data, but controller
expected only 1 byte value. Due to this controller evaluated rest of data as fault codes. The
new function has been added, now the random values are masked. DM1_serve_tdc function is
called only if the length of the incoming data is sufficient.
Background of the sensor calibration
To correct measuring error of each analog input (pressure, temperature, level) calibrating constants
within 10 % of measure range should be set. Two calibrating constants are set in physical units - bar,
o
C, % .Calibration is made by adding the value of setpoint AIxCalibration directly to the calculated
value at analog input.
Hint:
The calibration must be done at the operational point of the analog input (e.g. 80°C, 4,0Bar etc..)
Default sensor curves
There are 20 resistive curves available. The following table provides information on
minimum/maximum values of respective sensors. Actual values especially of temperature curves may
differ. Meaning is to prolong curve to the lower temperature values, so the cold engine will not raise
alarm fail sensor.

Hint:
When measured value is 6% out of range the Sensor Fail FLS is detected. You can find detailed
