DIAGNOSIS SYSTEM [ABS ACTUATOR AND ELECTRIC UNIT (CONTROL
UNIT)]
NOTE:
1: A brief moment of On/Off condition occurs every 20 seconds after ignition switch turned ON. This is not malfunction because it is an
operation for checking.
ACTIVE TEST
CAUTION:
• Do not perform active test while driving vehicle.
 Make sure to completely bleed air from brake system.
 The active test cannot be started when ABS warning lamp and brake warning lamp are ON.
 ABS warning lamp and brake warning lamp are ON during active test.
NOTE:
 When active test is performed while depressing the pedal, the pedal depression amount will change. This is
normal. (Only solenoid valve and ABS motor.)
 “TEST IS STOPPED” is displayed 10 seconds after operation start.
 After “TEST IS STOPPED” is displayed, to perform test again.

DescriptionINFOID:0000000003766748
PUMP
The pump returns the brake fluid stored in the reservoir to the master cylinder by reducing the pressure.
MOTOR
The motor drives the pump according to the signals transmitted by the ABS actuator and electric unit (control
unit).
MOTOR RELAY
Activates or deactivates motor according to the signals transmitted by the ABS actuator and electric unit (con-
trol unit).

DTC DETECTION LOGIC
DTC CONFIRMATION PROCEDURE
1.DTC REPRODUCTION PROCEDURE
1. Turn the ignition switch ON.
2. Perform ABS actuator and electric unit (control unit) self-diagnosis.
Is DTC
“C 1111” detected?
YES >> Proceed to diagnosis procedure. Refer to BRC-25, "Diagnosis Procedure".
NO >> INSPECTION END
Diagnosis ProcedureINFOID:0000000003766750
1.CHECK CONNECTOR
1. Turn the ignition switch OFF.
2. Disconnect ABS actuator and electric unit (control unit) connector.
3. Check terminal for deformation, disconnect, looseness, etc.
Is the inspection result normal?
YES >> GO TO 2.
NO >> Repair or replace damaged parts.
2.CHECK ABS MOTOR AND MOTOR RELAY POWER SUPPLY CIRCUIT
Check the voltage between the ABS actuator and electric unit (control unit) harness connector and ground.
Is the inspection result normal?
YES >> GO TO 3.
NO >> Repair or replace damaged parts.
3.CHECK ABS ACTUATOR AND ELECTRIC UNIT (CONTROL UNIT) GROUND CIRCUIT
Check the continuity between ABS actuator and electric unit (control unit) harness connector and ground.
