E9 Check ABS Control Module Ground

- Ignition switch OFF.

- Measure resistance between pin 1 (BK) of the 4-pin connector and ground.

- Is the resistance less than 5 ohms?

YES -- Replace ABS module.

NO -- Service circuit 57 (BK) for open.

NOTE: On early production vehicles, circuit 601 may change color from LB/PK to R through the harness connector. Circuit 603 may change color from DG to Y as it passes through the harness connector.
