2.CHECK ABS ACTUATOR AND ELECTRIC UNIT (CONTROL UNIT) POWER SUPPLY AND GROUND CIR-
CUIT Check the ABS actuator and electr ic unit (control unit) power supply and ground circuits. Refer to BRC-121,
"Diagnosis Procedure".
Is the inspection result normal?
YES >> GO TO 3.
NO >> Repair / replace harness, connector, fuse, or fusible link.
3.CHECK CONNECTOR AND TERMINAL
