JVM-407B with own SA of 20 wants to request the PGN 65253 Engine Hours
from an engine control unit with the SA 0. The SPN 247 Engine Total Hours of
Operation should be read from this PGN. It is therefore necessary to register
receipt of the SPN 247 by calling up the function SAEJ1939AddRx () .
The parameter
byPriority
is not explicitly specified when calling up the
function. In this case, the default value is used.
