how do you check the codes on these engines.
we were running it yesterday and the red light was on and horn was beeping.
it was running really rough when it did this.
oil on the dipstick is good and it has a good pee stream.

possibly overheated and warped the head.
check plugs for signs of water, do a compression check or leakdown test on the cylinders

The diagnostic software and cable is relatively cheap. Find it plenty of places. Last I checked it was under $100. This will give you codes and live data as well as the ECU tracked engine hours

That appears to be correct. It is an aftermarket cable and probably ripped off software but it may very well work. The real deal is around $200 now and is genuine Suzuki

I can’t get a link to display. Amazon does list the OEM Suzuki SDS
