A G2 system contains a Public and a Private network. There are 2 networks because they provide redundant signaling between the control head(s) and the engine EMM(s) thus providing an additional safety factor in the event of a loss of communication in one of the networks.
Code 114
Loss of NMEA 2000 network communication - EMM detects no communication on the NMEA 2000 network. Check NMEA 2000 devices, buss cables, tees and backbone cable.
Code 115
Loss of Remote Control network communication EMM detects no communication on the Remote Control network. Check remote control connections, buss cables, hubs and backbone cable.
See your dealer as there may be software updates to the controls and engine that may take care of the problem, but your dealer also has to check for poor connections, intermittent wiring faults, or other interruptions of both networks. They should also check or replace the key switch if needed as there is an improved design that may or may not be needed on your engine.
