IMPORTANT: Many heavy duty vehicles are changing
from the older J1587 communication standard to the
new J1939 communication standard. As a result, both
communication standards (J1587 and J1939) may be
available on vehicles equipped with the 9-Pin
Deutsche connection. In cases where no diagnostic
trouble codes are found or some of the data items
appear suspect in the J1939 standard, try the J1587
standard to verify the results.
