4 Troubleshooting
If you notice unexpected operation of the Maretron J2K100, follow the troubleshooting
procedures in this section to remedy simple problems.
Symptom Troubleshooting Procedure
No engine, transmission
or genset data visible on
NMEA 2000
®
network.
Ensure that the J1939 network is operational by observing J1939
gauges or displays. You should see information transmitted from
the engine, transmission, or genset displayed on the J1939
displays. If you don’t see data, try disconnecting the J1939
connection you made to the J2K100 as something may have been
connected incorrectly.
Once you are sure that the J1939 network is operational with a
J2K100 connected, ensure that the NMEA 2000
®
network is
operational by observing displays. You should see information
from components besides the ones attached to the J2K100 which
verifies an operational NMEA 2000
®
network. If you don’t see data,
try disconnecting the NMEA 2000 connection you made to the
J2K100 as something may have been connected incorrectly.
Once you are sure that the J1939 and NMEA 2000 networks are
operational with a connected J2K100, ensure that the NMEA
2000
®
connector is securely connected to the NMEA 2000
®
network and the J1939 connector is securely connected to the
J1939 network.
Ensure that the J2K100 has the appropriate NMEA 2000
®
PGNs
enabled as described in 2.5.5.
If these steps do not solve your problem, please contact Maretron Technical Support (refer to
Section 6 for contact information).
Warning: There are no user-serviceable components inside the Maretron J2K100. Opening
the J2K100 will expose the sensitive electronic components to adverse environmental
conditions that may render the unit inoperative. Please do not open the J2K100, as this will
automatically void the warranty. If service is required, please return the unit to an authorized
Maretron service location.
