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.

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.

DescriptionINFOID:0000000003766819
CAN (Controller Area Network) is a serial communication line for real time application. It is an on-vehicle mul-
tiplex communication line with high data communication speed and excellent error detection ability. Many elec-
tronic control units are equipped onto a vehicle, and each control unit shares information and links with other
control units during operation (not independent). In CAN communication, control units are connected with 2
communication lines (CAN-H line, CAN-L line) allowing a high rate of information transmission with less wiring.
Each control unit transmits/receives data but selectively reads required data only.
