I've been doing a somewhat leisurely brake caliper rebuild and fitting new Exact lines, pads and discs.
Once i finished I bled the brakes with the engine running in the order specified, but now have ABS light on

So tried the flash dash method and came up with these ABS codes 11- 12-13 all wheel fast sensor system (broken wire or short)
Has anyone come across this after doing work on the brakes before ?
Could it be due to air entering the ABS system and the code not being cleared
Any help much appreciated
