Hi have an abs problem that persists. Have a bmw c110 diagnostic tool. Says problem with front left sensor and a pulse problem in both front left and right. I have replaced both and tried erasing problem but abs light and run flat light keep coming on. Want to check the wiring from abs pump but need to know which wires to test in the 48 pin plug. It's a 2002 cooper. Any help appreciated
