SUBJECT:
ABS Sensor Lead Faults/Repair Procedure

MODELS:
E30, E32, E34

Situation:
Previously, if a problem was encountered in an ABS Sensor Lead on one of these models, the repair required replacement of the vehicle main harness. Separate leads are now available that allow individual replacement of each of the 4 separate sensor leads.

In most cases a fault in a sensor lead will show up as an intermittent fault (ABS warning lamp comes on while driving).

If the ABS warning lamp is continuously illuminated after starting the vehicle, the BMW Service Tester should be used to diagnose the problem.

Parts Information:
These sensor leads are available under the following part numbers.

One lead and the necessary connectors for the repair are included in each package.

Sensor lead E32/E34 - P/N 61 13 9 061 686

Sensor lead E30 - P/N 61 13 9 061 687
