CAUTION:
After disconnecting the CONSULT vehicle interface (VI) from the data link connector, the ignition must
be cycled OFF → ON (for at least 5 seconds) → OFF. If this step is not performed, the BCM may not go
to “sleep mode”, potentiall y causing a discharged battery and a no-start condition.
NOTE:
This vehicle is diagnosed using the CONSULT-III plus.
• When CONSULT is connected with a data link connector equipped on the vehicle side, it will communicate with the control unit
equipped in the vehicle and then enable various kinds of diagnos-
tic tests.
• Refer to “CONSULT-III plus Operation Manual” for more informa- tion.

U1000 CAN COMM CIRCUIT
DescriptionINFOID:0000000009463121
CAN (Controller Area Network) is a serial communication system for real time application. It is an on-vehicle
multiplex communication system with high data communication speed and excellent error detection ability.
Many electronic control units are equipped onto vehicl es, and each control unit shares information and links
with other control units during operation (not independent ). In CAN communication, control units are con-
nected with two 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. Refer to
LAN-32, "CAN COMMUNICATION SYSTEM : CAN Communication Signal Chart"
.

DTC CONFIRMATION PROCEDURE
1.PERFORM SELF-DIAGNOSIS
With CONSULT
1. Turn ignition switch ON and wait for 2 seconds or more.
2. Using CONSULT, perform “SELF- DIAGNOSIS RESULTS” of HVAC.
3. Check if any DTC No. is displayed in the self-diagnosis results.
Is DTC detected?
YES >> Refer to HAC-55, "Diagnosis Procedure".
NO >> Refer to GI-43, "Intermittent Incident"
.
Diagnosis ProcedureINFOID:0000000009463123

How to Use CAN Communication Signal ChartINFOID:0000000009461401
The CAN communication signal chart lists the signals trans
mitted/received among control units. It is useful for
detecting the root cause by finding a signal related to the symptom, and by checking transmission and recep-
tion unit.

CAN COMMUNICATION SIGNAL GENERATION
• Termination circuits (resistors) are connected ac ross the CAN communication system. When transmitting a
CAN communication signal, each control unit passes a cu rrent to the CAN-H line and the current returns to
the CAN-L line.
