PRECAUTIONS
Precaution for Trouble DiagnosisINFOID:0000000001451944
CAUTION:
• Never apply 7.0 V or more to the measurement terminal.
 Use a tester with open terminal voltage of 7.0 V or less.
 Turn the ignition switch OFF and disconnect th e battery cable from the negative terminal when
checking the harness.
Precaution for Harness RepairINFOID:0000000001451945
• Solder the repaired area and wrap tape around the soldered area. NOTE:
A fray of twisted lines must be within 110 mm (4.33 in).
 Bypass connection is never allowed at the repaired area. NOTE:
Bypass connection may cause CAN communication error. The
spliced wire becomes separated and t he characteristics of twisted
line are lost.
 Replace the applicable harness as an assembly if error is detected on the shield lines of CAN communica-
tion line.

SYSTEM DESCRIPTION
SYSTEM DESCRIPTION
CAN Communication SystemINFOID:0000000001451946
 CAN communication is a multiplex communication syste
m. This enables the system to transmit and receive
large quantities of data at high speed by connecting c ontrol units with two communication lines (CAN-H and
CAN-L).
 Control units on the CAN network transmit signals us ing the CAN communication control circuit. They
receive only necessary signals from other c ontrol units to operate various functions.
 CAN communication lines adopt twisted-pair line st yle (two lines twisted) for noise immunity.
SYSTEM DIAGRAM
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.
SKIB8887E
Component Description
Main line CAN communication line between splices
Branch line CAN communication line between splice and a control unit
Splice A point connecting a branch line with a main line
Termination circuit Refer to "CAN COMMUNICATION CONTROL CIRCUIT".

CAN COMMUNICATION CONTROL CIRCUIT
*: These are the only control units wired with both ends of CAN communication system.
Diag on CANINFOID:0000000001451947
DESCRIPTION
“Diag on CAN” is a diagnosis using CAN communication instead of previous DDL1 and DDL2 communication
lines, between control units and diagnosis unit.
SKIB8713E
Component System description
CAN controller It controls CAN communication signal transmission and reception, error detection, etc.
Transceiver IC It converts digital signal into CAN communication signal, and CAN communication signal into digital
signal.
Noise filter It eliminates noise of CAN communication signal.
Termination circuit
*
(Resistance of approx. 120 Ω) It produces potential difference.

TROUBLE DIAGNOSIS
Condition of Error DetectionINFOID:0000000001451948
“U1000” or “U1001” is indicated on SELF-DIAG RESULTS on CONSULT-III if CAN communication signal is
not transmitted or received between units for 2 seconds or more.
CAN COMMUNICATION SYSTEM ERROR
 CAN communication line open (CAN-H, CAN-L, or both)
 CAN communication line short (ground, betw een CAN communication lines, other harnesses)
 Error of CAN communication control circuit of the unit connected to CAN communication line
WHEN “U1000” OR “U1001” IS INDICATED EV EN THOUGH CAN COMMUNICATION SYSTEM IS
NORMAL
 Removal/installation of parts: Error may be detec ted when removing and installing CAN communication unit
and related parts while turning the ignition switch ON. (A DTC except for CAN communication may be
detected.)
 Fuse blown out (removed): CAN communication of the unit may cease.
 Voltage drop: Error may be detected if voltage drops due to discharged battery when turning the ignition
switch ON (Depending on the control unit which carries out CAN communication).
 Error may be detected if the power supply circuit of the control unit, which carries out CAN communication,
malfunctions (Depending on the control unit which carries out CAN communication).
 Error may be detected if reprogramming is not completed normally.
NOTE:
CAN communication system is normal if “U1000” or “U 1001” is indicated on SELF-DIAG RESULTS of CON-
SULT-III under the above conditions. Erase the memory of the self-diagnosis of each unit.
Symptom When Error Occurs in CAN Communication SystemINFOID:0000000001451949
In CAN communication system, multiple units mutually transmit and receive signals. Each unit cannot transmit
and receive signals if any error occurs on CAN communicati on line. Under this condition, multiple control units
related to the root cause malfunction or go into fail-safe mode.
ERROR EXAMPLE
NOTE:
 Each vehicle differs in symptom of each unit under fail-safe mode and CAN communication line wiring.
 Refer to LAN-37, "
Abbreviation List" for the unit abbreviation.
Example: TCM branch line open circuit
SKIB8738E
Unit name Symptom
ECM Engine torque limiting is affected, and shift harshness increases.
