Precautions for Trouble DiagnosisINFOID:0000000009461391
CAUTION:
Follow the instructions listed below. Fail ure to do this may cause damage to parts:
• 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.
Precautions for Harness RepairINFOID:0000000009461392
• 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 the 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.

CAN COMMUNICATION SYSTEM
CAN COMMUNICATION SYSTEM : System DescriptionINFOID:0000000009461393
CAN (Controller Area Network) is a serial communication li
ne 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.

DESCRIPTION
“Diag on CAN” is a diagnosis method which uses t
he CAN communication line for the communication between
the control unit and the diagnostic tool.
Name Harness Description
DDL1 Tx
Rx For communications with the diagnostic tool. (CAN-H and CAN-L are used for control-
ling)
DDL2 K-LINE For communications with the diagnostic tool. (CAN-H and CAN-L are used for control-
ling)
Diag on CAN CAN-H
CAN-L For communications with the diagnostic tool. (CAN-H and CAN-L are also used for con-
trol and diagnoses.)

Condition of Error DetectionINFOID:0000000009461396
DTC (e.g. U1000 and U1001) of CAN communication is
indicated on SELF-DIAG RESULTS on CONSULT if a
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 DTC OF CAN COMMUNICATION IS I NDICATED EVEN 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 DTC of CAN communication is indicated on SELF-DIAG RESULTS of
CONSULT under the above conditions. Erase the memory of the self-diagnosis of each control unit.
