Wildcat 1000 : Need help!

[southwestvawildcat]

So I just bought a 2012 Wildcat 1000.  When I bought it, it was throwing the code P0500.  I followed suit and replaced the speed trigger and speed sensor.  The speedo and odometer still didn't work.  I went ahead and cleaned all connections including to the LCD gauge.  This past weekend, we rode and at acceleration I continued getting the P0500 code along with C1312.  After riding a couple miles, the speedo starting acting crazy and then all of a sudden worked.  I found after I cut off the machine, on restart, back to the codes until I rode a couple miles.  Any help on how to fix this issue would be greatly appreciated!  Thanks in advance.

Not sure if you have this but the service manual is available here; https://support.countrycat.com/posts/2799423-2012-wildcat-service-manual

I do, but I've replaced what those codes refer to and can not find any broken wires.
