CAN COMMUNICATION SYSTEM
System DescriptionINFOID:0000000001162753
 CAN communication is a multiplex communication system. This enables the system to transmit and receive
large quantities of data at high speed by connecting control units with two communication lines (CAN-H and
CAN-L).
 Control units on the CAN network transmit signals using the CAN communication control circuit. They
receive only necessary signals from other control units to operate various functions.
 CAN communication lines adopt twisted-pair line style (two lines twisted) for noise immunity.
System DiagramINFOID:0000000001162754
Each control unit passes an electric current to the termination circuits when transmitting CAN communication
signal. The termination circuits produce an electrical potential difference between CAN-H and CAN-L. CAN
communication system transmits and receives CAN communication signals by the potential difference.

DTC CONFIRMATION PROCEDURE
1.PERFORM DTC CONFIRMATION PROCEDURE
1. Turn ignition switch ON.
2. Check “Self diagnostic result” with CONSULT-III.
Is DTC detected?
YES >> Refer to SEC-30, "Diagnosis Procedure".
NO >> INSPECTION END.
Diagnosis ProcedureINFOID:0000000001404068
1.PERFORM INITIALIZATION
Perform initialization with CONSULT-III. Re-register all mechanical keys.
For initialization and registration of mechanical key. Refer to CONSULT-III Operation Manual.
Can the system be initialized and can the engine be started with re-registered mechanical key?
YES >> ID was unregistered.
NO >> GO TO 2.
2.PEPLACE BCM
1. Replace BCM. Refer to XX-XX, "*****"
.
2. Perform initialization with CONSULT-III. Re-register all mechanical keys.
For initialization and registration of mechanical key. Refer to CONSULT-III Operation Manual .
Can the system be initialized and can the engine be started with re-registered mechanical key?
YES >> BCM is malfunctioning.
NO >> GO TO 3.
3.PEPLACE ECM
1. Replace ECM. Refer to the following page.
- HR16DE (WITH EUR-OBD): XX-XX, "*****"
- HR16DE (WITHOUT EUR-OBD): XX-XX, "*****"
- MR18DE (WITH EURO-OBD): XX-XX, "*****"
