YES -Replace the appropriate wheel speed sensor (see WHEEL SPEED
SENSOR REPLACEMENT ).

NO -Repair short in the wire between the appropriate wheel speed sensor and
the VSA modulator-control unit.

10. Disconnect the appropriate wheel speed sensor 2P connector.
11. On the sensor side, check for continuity between appropriate wheel speed

sensor 2P connector terminals No. 1 and No. 2, then check for continuity
between the same terminals and reverse the positive and negative tester probes.
