With the ALERT_x and TRANS_ALERT_x parameters, you can independently display up to 10 diagnostic
codes on engine and transmission status bits in NMEA 2000 (see V.10 and V.34).
3. Bombardier BRP Engines
The Engine Gateway supports native fault codes of BRP engines in addition to fault and diagnostics codes
transmitted with J1939 DM1 messages (see Table 2 above).
