Check ABS motor supply under loaded condition (connector E36 terminals 1 and 2).

Is the inspection result normal?

YES

>> GO TO 4.

NO

>> Check both power supply and ground circuit.

4.

CHECK ABS ACTUATOR AND ELECTRIC UNIT (CONTROL UNIT) GROUND CIRCUIT

1.

Turn ignition switch OFF.

2.

Disconnect ABS actuator and electric unit (control unit) connector.

3.

Check continuity between ABS actuator and electric unit (control unit) harness connector terminals and
ground.

Is the inspection result normal?

YES

>> Check battery for terminal looseness, low voltage, etc. if any malfunction is found, repair malfunc-

tioning parts.

NO

>> Repair or replace harness. (Check ABS ground bolt for tightness and corrosion.)
