A1 2-3-2 is "speedometer signal missing"
A3 3-1-2 is "rt. rear wheel sensor signal missing"

speedo sensor is in the trans. above the rt. drive shaft but could also be the speedo itself. clean all applicable connectors and reset the code before replacement though.

as far as ABS this code is usually precurser to contro unit replacement before you do that however I would clean the rear ABS sensors,completely flush the brake fluid, erase the code and see if it comes back.... if it does then change the ABS control unit. There are two variations for this year model one with TRACS and one with out ....be sure and get the correct one!

good luck ...
