CAN COMMUNICATION

System Description

INFOID:0000000004211754

CAN (Controller Area Network) is a serial communication line 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.

This vehicle has two types of CAN communication systems; CAN and HEV SYSTEM CAN. The hybrid vehicle

control ECU functions as the network gateway ECU for signal transmitting/receiving between CAN and HEV

SYSTEM CAN.

Refer to 

LAN-27, "CAN Communication Signal Chart"

, about CAN communication for detail.

ON BOARD DIAGNOSTIC (OBD) SYSTEM

ON BOARD DIAGNOSTIC (OBD) SYSTEM

Diagnosis Description

INFOID:0000000004211755

INTRODUCTION

The hybrid vehicle control ECU has an on board diagnostic system, which detects malfunctions related to

hybrid vehicle control system, sensors, actuators or HV battery systems, and records various diagnostic infor-

mation relating to the malfunction. The hybrid vehicle control ECU also illuminates the MIL and/or 3 warning

lights (Hybrid system warning light, High voltage battery warning light, Charge warning light) in the combina-

tion meter. For which light illuminates, refer to 

HBC-619, "DTC Index"

.

Three-digit information code (INF code) has been provided in the conventional DTC as subset of a primary

five-digit code. This enable the troubleshooting procedure to further narrow down a malfunctioning area to

identify a problem.

The above information can be checked using procedures listed in the table below.

×: Applicable  —:Not applicable

ONE TRIP DETECTION LOGIC

When a malfunction is detected, DTC and freeze frame data are stored in the hybrid vehicle control ECU

memory and illuminates the MIL and/or warning lights on the combination meter. Refer to 

HBC-619,

"DTC Index"

.

TWO TRIP DETECTION LOGIC

Specific on board diagnostic items have the two trip detection logic. When a malfunction is detected for the

first time, DTC is not stored in the hybrid vehicle control ECU memory. <1st trip>

If the same malfunction is detected again during the next drive, the DTC and Freeze Frame data are stored in

the hybrid vehicle control ECU memory, and the MIL and/or warning lights in the combination meter illumi-

nates. <2nd trip>

The “trip” in the “Two trip detection logic” means a driving mode in which self-diagnosis is performed during

vehicle operation. For the items which have the two trip detection logic, refer to 

HBC-619, "DTC Index"

.

HOW TO READ DTC

With CONSULT-III
With GST

CONSULT-III or GST (Generic Scan Tool) Examples: P0560, P0A1A, etc.

These DTCs are prescribed by SAE J2012.

(CONSULT-III also displays the malfunctioning component or system.)

DTC of a malfunction is displayed in SELF-DIAGNOSTIC RESULTS mode of CONSULT-III.

HOW TO ERASE DTC

 With CONSULT-III

The diagnostic information in the hybrid vehicle control ECU can be erased by selecting “Erase” in the” “SELF-

DIAG RESULTS” mode with CONSULT-III.

 With GST

The diagnostic information in the hybrid vehicle control ECU can be erased by selecting Service $04 with GST.
