I'm working at a jetski rental and running into a strange issue. I've read through a lot of the forums discussing DESS post issues but still haven't been able to resolve my problem. To start, the ski is a 2016 gts 4-tec. The ski starts and runs fine but will constantly be reading the key. I've switched out the ecm, post, key, and the wiring harness from the front but still no luck of getting rid of the "reading key" message. The parts were from an identical ski although, I guess they could also be faulty. Any thoughts?
