I get the 9999 from time to time in my CX (D16Y7) I think it's just a software issue.
I was also under the impression that the HX was a 50 state model, while the VX had a 49 and CA variant.
However, Car-part.com shows no selection for CA/49 models. So it is possible one could exist for the HX (D16Y5).
