Hello everyone my name is Bill, I brought my brand new 2023 Zforce 950 HO sport home tonight, I took it around the yard about 5 times and when I stopped it stalled out and now will not start.  It rolls strong but doesn't even try to start.  The codes on the screen are flashing P05601C, P062811, P026111, P026411, P00311, P069111.  Ive tried diconnecting the battery terminals to reset the ecm with no luck. I put it on a charger in case low voltage was an issue but that's fine too.  There is almost zero info on the web for ecm codes on these things.  I contacted the dealer and they said if it doesn't correct itself they will pick it up on tuesday when they open again to troubleshoot it.

Here are the fault codes for the 2020 and up...I believe. From what I see they mostly are low voltage codes which...in the past.. indicates loose connections on the battery...and it is up to the dealer to install the battery and many came out with loose terminals, a main harness connector is loose...or the harness has a problem somewhere . Check all the battery connections first then start from there and work out on connectors and look for anything like a harness problem especially close to exhaust pipes.

And I think this service manual covers yours so download it too. These links expire in 48 hours so get them soon.

Thank you for the info and manuals.  I will check connections today to see if anything came loose! Otherwise the dealer is going to pick it up on Tuesday they said.  I'll keep you posted as to what they say!

Any trick to do a hard reset on the ecm?  I tried leaving battery unhooked for a while but that didn't work!

Not sure about the new ones but the older ones don't store codes. In all units new or old the codes won't display if the problem is fixed so if the codes are still there...so is the problem. If the new ones do store codes then it will take one of their readers..or an adapted OBD2 scanner/reader to delete codes.

You will need an OBDII code reader. The ECM and diagnostic port are behind the passenger seat backrest. You need to remove the plastic panel to access the OBD port.

Those codes sound like an electrical issue- I found my wiring harness got pinched in between the engine mount (underneath center console) so check battery connections are good and tight as well as inspect the electrical harness for damage

I am having the same problems. Did you find out what it was?
