[CA] [CA11] Yamaha CL 6YG stopped displaying 2019 F70 Yamaha engine data - troubleshooting

ray18,

Q1. Could a dying battery cause my F70 motor ECM to stop sending data to gateway?
A1. Yes. All product testing / verification of operational state should only be performed after fully charging the vessel's batteries.

A2. I think I may need a ECM reset like what we do for cars using OBD II reset tool. If yes, is there a cheap solution to reset the Yamaha 70 hp ECM other than taking it to the dealer?
A2. It is recommended that this question be addressed to Yamaha.

Q3. isn't LH 3.11.42 essentially a NMEA 2000 analyzer? Why do I still need to get a NMEA 2000 analyzer
A3. To a limited degree, yes. However, N2K analyzers such as that which was previously referenced will yield a greater down of the data within NMEA 2000 PGNs. Such gateways can often be useful in diagnosing issues on the engine backbone as well.
