No ECM signal warning?

Recommended Posts

Had this pop up on my screen 2 times this week. All gauges and needles go dead. All dash is locked up no buttons work. Boat continued to run properly just can't use cruise, read speed,rpm,temp,lake temp, engine hours,ETC. All read 0. This happened after boat was running and all things were normal. After shutting off and restarting, all went back to normal. Any Ideas? I love this boat but it sure is giving me some issues this year.

Check your cannon (engine to dashboard wireing) plug.

Is that a round plug in the engine compartment?

On an 06 it is actually a square connector that goes into the ECM should on the starboard side of the motor. Probably has about a dozen wires going into/out of it. It is farily easy to find because the wires go into the stringer up to dash. So just find the bundle of wires sticking out of the stringer and follow to the connection. Also check the connections at the MMDC under the dash (black box).

What does ECM and MMDC stand for?

Engine Control Module - the engine computer, mounted above the transmission (probably behind a metal shroud)

Mini Multiple Data Collector (I kinda made that one up) - the computer under the dash that runs the gauge cluster
