   2. Disconnect ABS actuator and electric unit (control unit) connectors.
   3. Check connectors and terminals for deformation, disconnection, looseness or damage.

   Is the inspection result normal?

   YES 

   GO TO STEP 2  .

   NO 

   Repair or replace as necessary.

2. CHECK ABS ACTUATOR AND ELECTRIC UNIT (CONTROL UNIT) IGNITION POWER SUPPLY CIRCUIT
   
   

   Check voltage between ABS actuator and electric unit (control unit) connector E33 terminal 6 and ground.
