STRUCTURE
![](../../../img/54/ACB03533AE00ENG.png)
- The CAN bus line consists of 2 lines, CAN_L
and CAN_H (CAN Low and CAN High, respectively), as well as
2 terminal resistors (A
twisted-pair cable, highly resistant to noise, is used for the
communications line).
- The CAN bus line connecting the 2 terminal resistors is the main
bus line, and the
CAN bus line connecting each ECU is the sub-bus line.
- The terminal resistors are installed in the engine-ECU and
ETACS-ECU to stabilize communication
signals (The terminal resistance is set at approximately 120
Ω).
- The following components are connected in the CAN bus line as
follows.
- ETACS-ECU
- Combination meter
- SRS-ECU
- KOS&OSS-ECU <Vehicles with
KOS&OSS>
- ABS-ECU <Vehicles with ABS>
- ASTC-ECU <Vehicles with ASTC>
- Steering wheel sensor <Vehicles with
ASTC>
- A/T-ECU <A/T>
- Transfer-ECU <4WD (6M/T, A/T)>
- A/C-ECU <Vehicles with automatic
A/C>
- Engine-ECU
- Diagnosis connector
- Smartphone link display audio <Vehicles with
smartphone
link display audio>
