Got these three ABS codes, 42, 52, 54.  Cleared codes and they come back in a few minutes of driving.   1999 Subaru legacy sedan automatic 159,000 miles.   I'll clean ground wires close to ABS pump and start there.  My guess is that won't fix it though.   Brake lights work fine, I checked since bulbs/light issues can cause voltage problems and incidentally trip mulitple codes.   The reverse lights weren't working due to a broken wire where the harness pirvots for the trunk opening.  But
