2010 22ve Depth Sounder Reading 0.0

[dukesofhazzard]

Like the title says, on my 2010 22ve with tige touch the depth sounder just starting reading 0.0 I am not sure where to start looking so I thought I would ask here first. I have the boat at home now out of the water so can have a better look now. thanks in advance

anyone?

ok so I found the triducer, problem is I have no idea how to check it, the speedo works, temp seems to work good, it is making a ticking sound when put in a bucket of water, just not reading anything other than 0.0
Can these be fixed, new ones are 300$

So I've never heard of a transducer going bad, to me more likely a wiring or connector issue. I would say the next most likely item after that would be the sender/electronics... which probably is even more expensive.

The triducer reports data in two ways: A pulse train for the paddlewheel, and CAN data for all three sensors (paddlewheel, temperature, depth). If you're getting temperature then CAN is working, because that's the only way the triducer can communicate temperature. This means the questionable element is unfortunately the depth sensor portion of the triducer. That you can hear ticking suggests it's pinging with ultrasonics, so the transducer itself isn't broken.

The AirMar triducers allow you to configure them via CAN for various parameters, including enabling/disabling each sensor and changing the rate at which each sensor's data is reported on the CAN network. Maybe one of those parameters has gone wonky, and the unit is (not) doing exactly what it (believes it) is supposed to be (not) doing. I don't know of a way to reconfigure that from the onboard systems. If it were me, I would have the onboard system send out configuration data each time it powers up to avoid problems like this. Maybe they already do that, I haven't researched it.

Just trying to help with education. I don't have a good solution that doesn't involve having a known-good triducer to compare against, or a CAN network sniffer to examine the output data.

thanks, I read on another forum a mastercraft had the same prob and had to replace the triducer, I was hoping not, I can't believe how expensive it is. I will try connections tomorrow. Will have to start to trace back.

I filled up a bucket of water and placed triducer in there had no luck, so then I filled a plumbing pipe roughly 4-5 ft long with water and nothing, but all the time could hear the ticking. It is def picking up water temp, and if I spin the wheel I am getting a speed reading so they both work properly.
