Tyre pressures on CAN?
Posted: Wed Aug 15, 2018 11:27 pm
Hi all.
This will no doubt be the first post of many as I'm about to embark on a small project on my 2018 Wildtrack. I work as a mechanical engineer for a company in the rail industry, building road-rail vehicles. For many years we've used an external contractor for our electrical and control systems but next month are bringing it in-house.
As part of this we're employing an experienced PLC programmer with extensive CAN experience, in particular J1939 on off-highway vehicles.
I'm going to use the opportunity to grow my knowledge by developing a PLC system to do a few things on the vehicle, including a tyre inflation/deflation system where I can set the desired pressure on a small screen and let the PLC decide if it needs to let air out of the tyre or run the compressor.
Currently my plan for this is to fit a pressure transducer at the compressor end of the air hose but I was wondering if the tyre pressure information is on the CAN anywhere?
I've looked through he PID list provided on this forum and it's not listed - But has anyone found them?
