DESS not communicating

Bad DESS connection or wrong lanyard key.

The gauges will come to life even if you put the wrong key on it, they will also come to life for 33 seconds if you press the start button with the lanyard off which tests your start button function.

One beep = mpem does not recognize the key's embedded security code. You will need to take the ski
to a dealer or pwc shop who has a "BUDS" programmer. Try cleaning the key & post with a pencils eraser, and remove the dess post from the consul for examination of the wires for kinks and breakage.
check the four wireing points that are under the post. An MPEM can hold 7 key's codes in its ROM.
Did you check your 15A fuse in the rear black box for corrosion? that fuse supplies the MPEM it's main power. You should check the fuse holder as well, and clean & Dielectric grease all wire connectors.

A DESS switch has a 4 way connector up under the dash, if the terminals are corroded, or the switch is bad, the mpem never reads the lanyard code. This will block out the function of the starter switch to activate the solenoid in the coil box, as well as any spark from the now dead ignition.

I have the same problem with mine but I hav took it to a dealer but he can't reprogram the key as when. He connects the computer it can't read the mpem, I have checked all fuses all connections and all the cables are in good condition, I believe it to be the mpem itself but I don't know how to test the unit can you help?
Also mine recognizes the key as if I do self test without the key it beeps twice with it on it beeps once!

Thanks

I dont know why, but a dealer should have a good used post to try when they have issues. Although it should mean is just cant read the key, I bet its the post.

Post #4 X 2. Everything else must be connected. We also need to know what SKI you are talking about as the electrical systems very.
We suggest you also obtain & read the MANUAL specific to your ski so to be familiar with the jargon descriptions.

Is the small black wire connected at the battery?

Where are you not getting power? In older skis the battery cables rot internally at the lugs. Cut them off and re-solder & marine shrink-wrap.
Jump the starter solenoid posts with a wrench to see if theres power there.

The electrical componets must all be in working order before R&R a known good MPEM.
