U1000 CAN COMM CIRCUIT
DescriptionINFOID:0000000009460807
CAN (Controller Area Network) is a serial communication system for real time application. It is an on-vehicle
multiplex communication system with high data comm unication speed and excellent error detection ability.
Many electronic control units are equipped into vehicl es, and each control unit shares information and links
with other control units during operation. With CAN co mmunication, control units are connected with two com-
munication lines (CAN-H line, CAN-L line) allowing a hi gh rate of information transmission with less wiring.
Each control unit transmits and receives data but selectively reads required data only. Refer to LAN-32, "CAN
COMMUNICATION SYSTEM : CAN Communication Signal Chart".

HYDRAULIC PUMP ELECTRIC POWER ST EERING SYSTEM : System Description
INFOID:0000000009460344
• The system is composed primarily of the power steeri ng oil pump assembly (power steering control module,
power steering motor, power steering oil pump, and reservoir tank), hydraulic pipes, and steering gear
assembly.
• The power steering control module controls the speed of the power steering motor according to the vehicle
speed and steering angle speed. By changing the power st eering oil pump flow, the power steering control
module controls the steering assist force.
• According to the power steering motor control, the sy stem hydraulic pressure is transmitted from the power
steering motor to power steering oil pump. The power steering oil pump is driven by the system hydraulic
pressure.
• After engine start, the hydraulic pump electric power steering system performs control.
• When a malfunction occurs in the system, the fail-safe function stops the hydraulic pump electric power
steering system (manual steering state) or restricts it s operation (certain steering assist force). Refer to STC-
8, "HYDRAULIC PUMP ELECTRIC POWER STEERING SYSTEM : Fail-safe".
• When the power steering function is used continuously in an extreme manner, the protective function
reduces the output to the power steering motor. Refer to STC-9, "HYDRAULIC PUMP ELECTRIC POWER
STEERING SYSTEM : Protection Function".

• The fluid temperature sensor uses a thermistor, and
changes the signal voltage by converting changes in the
CVT fluid temperature to a resistance value. TCM eval uates the CVT fluid temperature from the signal volt-
age value.
