Hi, the c1c63 code indicates a unknown issue that could relate to a specific system or
component in your vehicle. This requires manufacturer specific diagnostics for
accurate identification. But you worked on the front bearings so check the abs sensor
wiring and conne ctors.

Hi, check if the left and right rotation of the wheels is the same, if so try a deep
reset,check the abs fuse,if it is blown it could trigger abs warning light to come on,also
disconnect battery cables and turn on the headlight switch to drain the system and so
reset the abs light.

Hi, you really must check the Subaru service manual for manufacture's -specific details
on c1c63. There is no other way because this code you gave is a unknown code.
