2.

DIAGNOSIS FOR DETECTED DTC

Perform diagnosis on the detected DTC and repair or replace the applicable item. Refer to 

CCS-91, "DTC

Index"

.

>> GO TO 6.

3.

PERFORM SELF-DIAGNOSIS OF ABS ACTUATOR AND ELECTRIC UNIT (CONTROL UNIT)

1.

Perform self-diagnosis of ABS actuator and electric unit (control unit).

2.

Check if DTC is detected. Refer to 

BRC-87, "DTC No. Index"

.

Is any DTC detected?

YES

>> GO TO 4.

NO

>> GO TO 5.

4.

REPAIR OR REPLACE APPLICABLE ITEM

Repair or replace the applicable item identified by the self-diagnosis result.

>> GO TO 6.

5.

REPLACE ICC SENSOR INTEGRATED UNIT

1.

Replace ICC sensor integrated unit.

2.

Adjust laser beam aiming. Refer to 

CCS-7, "LASER BEAM AIMING ADJUSTMENT : Special Repair

Requirement (Preparation)"

.

>> GO TO 6.

6.

CHECK ICC SYSTEM

U1000 CAN COMM CIRCUIT

U1000 CAN COMM CIRCUIT

Description

INFOID:0000000000965461

• CAN communication is a multiplex communication system. This enables it to transmit and receive many

communication signals at high speed by connecting control units with two communication lines (CAN-H and
CAN-L).

• Control units on the CAN network transmit signals with CAN communication control circuit in the control unit

and receive only necessary signals from other control units for various controls.

• CAN communication lines adopt twisted-pair line style (two lines twisted) for noise immunity.
