Error Code DTC 147

[JDFugit]

Just got this error code on 2022 Super Air Nautique G23:
DTC 147: ECM CAN COMMUNICATION ERROR. (LOSS OF CAN) CHECK EMERGENCY CUT-OFF SWITCH.
Anyone have any experience with this?

In my Range Rover That means the serial network, aka CANBUS cannot comm with your kill switch unit presumably. So i'd check the connections to that unit, perhaps it's fiber-optic if they are slick.

Hey there JDFugit,

I have the same DTC 147 error message which you encountered showing up on my rig (also have a 2022 G23). Did you get it resolved by chance? Any help is appreciated.

Thanks!

hello! its more than likely the plug on your dead man switch. pull the helm control pad up and find the plug where your dead man switch hooks to harness and mess with it, squeeze it you will hear the fuel pump click on and off and the volts on dash change. I butt spliced mine together and good to go. Nautique used deutsch connectors everywhere else and use some cheap connecter there. good luck!

I don't see that DTC documented in the PCM Diagnostic Service Manual.

Any body can help me with code DTC 147. What should I check or pay attention to?

Good news, I've solved the problem. ECM fuse showed 3.4V. The wire (power supply side) had a loose/bad connection. I put a 12v wire from the nearest fuse to the ECM fuse and the ignition started to work again. I will start trying to find the bad wire this weekend. If you guys know where the bad wire is located at, let me know to save my time, want to go surfing Thanks.

I traced the bad red wire to the battery switch box, 15Amp Circuit Breakers with Push Button Reset, the problem was in the fuse which was causing the loose connection.
