COMPONENTS FUNCTION DESCRIPTION
CAN CommunicationUGS000A7
SYSTEM DESCRIPTION
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.
For details, refer to LAN-47, "
CAN System Specification Chart" .
WGIA0187E
Component parts Function
EPS control unit
(Electric power steering control unit)

Outputs optimum assist torque signal to EPS motor.

Reduces output signals to EPS motor and protects EPS motor and EPS control unit when
using power steering continuously and excessively.

As a fail-safe function, turned off output signal to EPS motor and then enters a manual steer-
ing state, if malfunction is detected in EPS system.
EPS motor Products assist torque by control signal from EPS control unit.
Torque sensor Detects steering wheel turning force and outputs sensor signal to EPS control unit.
Reduction gear Increases motor-produced assist torque by worm gear and transmits it to column shaft.
EPS warning lamp Illuminates if malfunction is detected in electrical system of EPS system.
ECMTransmits the following signals via CAN communication to EPS control unit.

Engine status signal
ABS actuator and electric unit (con-
trol unit) (With ABS)Transmits the following signals via CAN communication to EPS control unit.

Vehicle speed signal
Combination meterTransmits the following signals via CAN communication to EPS control unit.

Vehicle speed signal
TCM (Without ABS)Transmits the following signals via CAN communication to EPS control unit.
