Most of the engine error codes point you in a specific direction rather that being specific about a problem. Not so with the ABS module. both of the codes point to the right rear wheel sensor. The 314 is no communication with the sensor, the 324 is a something strange happening but can communicate?

Either it is a bearing that is allowing the wheel to oscillate or a soldering gone bad in the ABS module. It is hard to examine the sensor as the rotor needs to be pulled off and the Ebrake gets in the way. If you pull the wheel, use a damp cloth to clean the ridges around the axle - the brake dust must not be made to go airborne. Inhaling it is dangerous.

The wiring needs to be inspected at the sensor. It is possible that chaffing occurred.

If the ABS still gets errors, then sending it off to Mattty Moo for soldering is required.
