The device JVM-407B with the own SA of 20 wants to receive and display the
current fuel temperature. The parameters InhibitTime and EventTime are not
explicitly specified when calling up the function. In this case, the default values
are used. The controller for capturing the fuel temperature has got SA 0. In
practice, the address of the controller can be found in the engine
manufacturer's documentation.
The fuel temperature has the SPN 174 and is a component (byte 2) of the
PGN 65262 Engine Temperature 1.
