CAN COMMUNICATION SYSTEM

1OUTLINE

1-1 DESCRIPTION

1.A CAN

Å•g,DK_MÅ§

communication system which controls data relating to the power train at a higher speed

is used in all vehicles.

2.The CAN system sends over a single communications line (twisted pair cable) multiple items of information and data which have been converted into digital form by a communication circuit. This system reduces the number of the wiring harnesses and the size of the electronic control system for the systems that connect the input side (sensors, switches, etc.), the control units and the output side (display lamps, etc.).

3.The CAN communication system in use is a daisy chain type network with several computers connected to a pair of communication lines.

NOTE

• ~1:CAN stands for Controller Area Network. It is the serial communication based on the ISO

standard (ISO011898).

2-1 COMMUNICATION CONTROL

1. A CAN communication system has two communication lines (bus) acting as a pair and the bus level

Å•g,DK_MÅ§Å•g,DK_MÅ§

is determined by the voltage differential between them. The two lines are called CAN

high (CANH) and CAN low (CANL) respectively. Data is transmitted at the rate of 500kbps

Å•g,DK_MÅ§

a digital signal according to the CAN dedicated communication protocol.

NOTE

• ~2: The bus level has a dominant level and a recessive level. CAN communication system logic deems dominant to be 808 and recessive to be 818.

• ~3: The signal rate of data transmission is expressed in bits per second (bps). 8500kbps8 means that 500,000 bits of data are transmitted per second.

2-2 COMMUNICATION PROTOCOL

1.The CAN communication system is a multiplex systems in which all the ECU's in the network use a pair of communication lines (bus). Any of the ECU's can transmit data if the CAN bus is in an idol (open) state. Therefore, each ECU performs the communication according to the common communication protocol so that the communication can be done smoothly and securely.

2. Under CAN communication protocol all the ECU's share a common pair of communication lines and have the right to start transmitting data. CSMA/CD (Carrier Sense Multiple Access / Collision Detection)

Å•g,DK_MÅ§

is the protocol used for sending data to the communication line.

NOTE

• ~4: CSMA/CD stands for Carrier Sense Multiple Access with Collision Detection. It is a commu-

nication access protocol where ECU's check the status of the communication line (carrier) and only if there is no other data flowing will they start to send data of their own. Further, in addition to this, if a collision of data is detected (i.e. with data that has been transmitted by another ECU at the same time), the offending ECU will wait for a fixed period of time and then resend the data.

3.ECU's start to transmit data when other data is not flowing in the CAN bus, but if two or more ECU's start to transmit data simultaneously then the priority of the data is determined by the ID which the transmitted data itself contains.

2-4 DIAGNOSIS (SELF-DIAGNOSIS) FUNCTION

Diagnostics means failure diagnosis. This is a function by which if there are any abnormalities in the input signal the ECU will inform a mechanic/technician of the abnormal item. CAN communication failure diagnosis sets up a separate diagnosis code for each ECU which constitutes the CAN. Please refer to the repair/maintenance manual for details of the failure diagnosis function.

2-5 FAIL-SAFE CONTROL

If the CAN communication system continues operating in the event of abnormalities such as open wires or short circuits in the CAN communication line and communication abnormality between ECU's, there may be the possibility that the abnormalities may effect the control of each system. Under these circumstances each ECU will come under the control of a preset internal control system. For details of the fail-safe controls please refer to the item of each system which makes up the CAN.

LIN COMMUNICATION SYSTEM

1OUTLINE

1-1 DESCRIPTION

1.All vehicles are equipped with LIN communication (LIN: Local Interconnect Network) *.

2.The LIN communication consists of the meter ECU and ITC.

3.Multiplex communication is a system in which plural ECU's are connected to a single communication line to provide mutual data exchange. This has made it possible to integrate the system and prevent the number of wires from increasing when a function is added.

4.Controls actually taking place in the multiplex communications are the wake-up/sleep controls, system controls by applicable ECU and so forth.

5.A diagnosis function is provided that will inform the operator of any abnormality of the system. Also, fail-safe functions are provided that will assure the minimum functions for each ECU and protect the systems when abnormal communications occur between the ECUs.

6.The communication method employs a single master system in which the meter ECU controls the sleep (low current mode), wake-up (standby mode), etc. of the communication applicable ECU.

NOTE

• *: The LIN communication is a multiplex communication network mainly intended for the data communications between the body-related control ECUs.

2-1 COMMUNICATION CONTROL

2-1-1 DESCRIPTION

The meter ECU controls the following items.

1.Evaluation of presence/non-presence of ECU

2.Communication start informing control

3.Wake-up/sleep control

2-1-2 EVALUATION OF PRESENCE/NON-PRESENCE OF ECU

The meter ECU detects the presence of the ECU every time the battery power supply is turned on.

1.When the LIN communication applicable ECU is not connected to the meter ECU, or when it does not

respond to the meter ECU due to failure, etc. of the LIN communication applicable ECU, the meter ECU transmits a command to other ECUs that have been judged to be present to perform such communication control that is to be carried out when the ECU that has made no response is not mounted (Evaluation of ECU non-presence).

2.The meter ECU, after detecting the presence of the ECU, continues to monitor ECU connecting status

at constant intervals.

3.When the LIN communication applicable ECU responds properly to the meter ECU during the ECU

presence/non-presence evaluation, or when the ECU that has made no response returns to the normal condition and makes a proper response after the ECU has been judged not to be present, the meter ECU transmits a command to other LIN communication applicable ECUs to perform such communication control that is to be carried out when the ECU that has made a response is mounted (Evaluation of ECU presence).

2-1-3 COMMUNICATION START CONTROL

The communication start is always started from the meter ECU. The signal of communication start is transmitted to other ECU.

2-1-4 WAKE-UP/SLEEP CONTROL

When transferring to the sleep (the low current mode), or transferring from the sleep (the low current mode) to the wake-up (the standby mode), the meter ECU transmits a transfer start command to the other LIN communication applicable ECUs, thereby transferring to the wake-up/sleep control.

2-2 WAKE-UP/SLEEP FUNCTION

2-2-1 DESCRIPTION

The LIN communication system is equipped with a wake-up/sleep function to reduce the current used when the IG switch is in the ACC and LOCK positions.

2-2-2 CONDITIONS FOR REALIZING SLEEP

When the following conditions 1 and 2, or the condition 3 is satisfied, the meter ECU sends a sleep command to each ECU, thus transferring to the sleep state (the low current mode).

1.The IG switch is set to the ACC position or the LOCK position.

2.The meter ECU received the information that the control of each ECU is complete, and the control of

the meter itself is complete.

3.Ten minutes have passed after the IG switch was set to the ACC position or the LOCK position, with

the door open (the battery discharging prevention function).

2-2-3 CONDITIONS FOR REALIZING WAKE-UP

When either of the following conditions is satisfied, the meter ECU sends a wake-up command to each ECU, thus transferring to the wake-up state (the standby mode).

1.Cases where there is a change in the data to be communicated at each ECU, and the ECU transmits

a wake-up (the standby mode) signal to the meter ECU.

2.Cases where the IG switch is turned from the ACC or LOCK position to the ON position.

3.Immediately after connecting a battery.

L2–17

2-3 LIN COMMUNICATION PROTOCOL (COMMUNICATION REGULATION)

1.The LIN communication system is a two-way interactive time-division multiplexing communication system, where all ECUs that make up the network can send and receive data by delaying the timing for using a communication line in order to share a single communication line. Each ECU, therefore, communicates according to the common communication protocol (communication regulation) to ensure smooth and reliable communication.

2.The data used by the LIN communication system consist of digital signals that include information such as ID to identify each ECU (node ID) and contents of communication data.

3.In order for all ECUs to be able to communicate by sharing a single communication line, based on the specified transmission time schedule, the single master system is employed as a communication regulation for the communication line, in which the meter ECU controls the communication timing, sleep (the low current mode) and wake-up (the standby mode), etc. of the communication applicable ECU.

2-4 DIAGNOSIS (ONBOARD DIAGNOSIS FUNCTION)

This is a function whereby the ECU informs the inspection operator of the abnormal items when there has been a failure in the system. When failure takes place, the ECU memorizes the abnormal item. Please refer to the repair manual for details concerning the diagnosis.

2-5 FAIL-SAFE FUNCTION

When communication remains unestablished between the applicable ECU and the meter ECU for a certain length of time, the predetermined control is performed by transferring to the fail-safe mode.

Conditions of each system during the fail-safe mode

CAUTION

• When the meter ECU transfers to the fail-safe mode, the ITC, being unable to communicate with the meter ECU, will transfer to the fail-safe mode.

Applicable ECU Condition

2-3 CONTROL PANEL

A three-dial type control panel is employed. The dial pointer adopts night illumination to assure easy operation and reading night time. The blower switch can be adjusted over four stages.

The illustration shows a typical example.

2-4 HEATER CORE

The heater core employs a small, lightweight SFA heater core @ (SFA: straight flow aluminum). The SFA heater core @ is more compact than conventional SFA heater cores because of the reduction in tank width and height/miniaturization of the core (core area expansion). This has achieved increased air flow, noise reduction, and an improvement in heating capacity. The SFA heater core @ is constructed from tubes, fins and capsules and the result has been that by flattening the tubes the heat transfer rate has been improved as well as producing a lightweight, small size heater. Further, the use of aluminum makes the heater more environmentally friendly.

2-5 EVAPORATOR

The evaporator employs a small, lightweight type RS Evaporator (RS: Revolutionary Super Slim).

The RS evaporator consists of a tank, tubes and cooling fins. Thanks to the press molding of the tube, minute flow paths have been formed and this leads to improved heat transfer capability and very thin dimensions. Further, the RS evaporator has improved heat transfer due to the reduced fin height, tube thickness, and fin pitch, and the unit is much reduced in size and weight due to the reduced stock thickness of the core material. The evaporator is coated with a hydrophilic plastic film which contains anti-bacteria agent to control the breeding of germs and bacteria which can lead to unpleasant smells. In consideration of the environment the surface treatment is chrome-free.

2-6 COMPRESSOR

Vane type compressor is employed.

2-7 CONDENSER

A new type of sub cooling condenser is used which has improved performance with its miniaturized core and an increased effective surface area, compared with the conventional ones. Inside the sub cooling condenser are provided the condensing section, the modulator and the over cooling section (sub cooling section). The refrigerant vapor goes through a 2-stage condensation process which lead to nearly 100% liquidizing. Further, the modulator separates the gas and liquid.

W13H1006T16

(2) Construction and operation

1.The resistance of the MRE becomes maximum when the direction of the electric current flowing in the element becomes parallel to the direction of the line of magnetic force. Conversely, the resistance becomes minimum when the electric current intersects with the direction of the line of magnetic force.

2.The direction of the line of magnetic force is determined by the rotation of the magnetized eight-pole magnet in the magnet ring. The MRE output becomes an eight-cycle alternating waveform per rotation of the magnet ring. The comparator converts these waveforms into eight-pulse short waveforms and the divider transforms them into four cycles. Finally, it will be outputted to the combination meter.

KEY-LESS ENTRY SYSTEM

1OUTLINE

1-1 DESCRIPTION

1.The radio wave type keyless entry system is provided on some specifications. The "LOCK" and "UNLOCK" operations for the front doors, rear doors and back door can be performed by the remote control operation.

2.The remote control of locking all the doors is possible by pushing the switch of the transmitter which is apart from the key, thus sending weak waves.

3.The operation range of remote control is approx. 3 meters in radius from the center of the vehicle. However, the range might be reduced or the function could be disabled due to the battery drain, strong radio wave or noise. Also the operation range might be affected by the shape of the vehicle.

4.The LIN communication system is employed in a part of the system circuit.
