I am having asr abs light issues

several months ago they would come on when I hit a bump. Kill and restart and lights stayed off.

recently, the lights stay on at start up.

38 pin test pin #6 4 blinks. Open circuit rear left.

both rear sensors cleaned and ohm out at 1600 which seems fine. I have checked at both sides (under car and in cabin) of the multi pin connector by the fuel pump.

so far I have spent several evenings looking for cracked damaged wiring from the multi pin inside the cabin, through the rocker and under the dash but have not found a thing wrong or obvious.

I am trying to avoid buying a new used rear speed sensor if I don’t have to.

any ideas what the problem could be?
