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
“C1140” detected?
YES >> Proceed to diagnosis procedure. Refer to BRC-36, "Diagnosis Procedure".
NO >> INSPECTION END
Diagnosis ProcedureINFOID:0000000003766755
1.CHECK CONNECTOR
1. Turn the ignition switch OFF.
2. Disconnect ABS actuator and electric unit (control unit) connector.
3. Check terminal for deformation, disconnection, looseness, etc.
Is the inspection result normal?
YES >> GO TO 2.
NO >> Repair or replace damaged parts.
2.CHECK SOLENOID AND ACTUATOR RELAY POWER SUPPLY CIRCUIT
Check the voltage between 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 SOLENOID AND ACTUATOR RELAY GROUND CIRCUIT
Check the continuity between ABS actuator and electric unit (control unit) harness connector and ground.
DTC Display item Malfunction detected condition Possible cause

Component InspectionINFOID:0000000003767291
1.CHECK ACTIVE TEST
1. On “ACTIVE TEST”, select “ABS MOTOR”.
2. Touch “On” and “Off” on screen. Make sure motor relay and actuator relay operates as shown in table
below.
NOTE:
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.
Is the inspection result normal?
YES >> INSPECTION END
NO >> Proceed to diagnosis procedure. Refer to BRC-36, "
Diagnosis Procedure".
