U1000 CAN COMM CIRCUIT
DescriptionINFOID:0000000009464757
CAN COMMUNICATION
CAN (Controller Area Network) is a serial communication line for real time applications. It is an on-vehicle mul-
tiplex communication line with high data communicati on speed and excellent error detection ability. Modern
vehicle is equipped with many electronic control units , 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, CAN-L) allowing a high rate of information transmission with less wiring.
Each control unit transmits/receives data but selectively reads the required data only.
CAN communication signal chart. Refer to LAN-32, "CAN COMMUNICATION SYSTEM : CAN Communica-
tion Signal Chart".
ITS COMMUNICATION
• ITS communication is a multiplex communication syste m. This enables the system to transmit and receive
large quantities of data at high speed by connec ting control units with 2 communication lines.
• ITS communication lines adopt twisted-pair line st yle (two lines twisted) for noise immunity.

FUNCTION DESCRIPTION
• The BSW system can help alert the driver of ot her vehicles in adjacent lanes when changing lanes.
• The BSW system uses rear view camera near the rear bumper to detect vehicles in an adjacent lane.
• The rear view camera can detect vehicles on either si de of vehicle within the detection zone shown as illus-
trated.
• This detection zone starts from the back of the v ehicle and extends approximately 3.0 m (10 ft) behind the
rear bumper, and approximately 13.0 m (10 ft) sideways.
• The BSW system operates above approximately 32 km/h (20 MPH).
• If the rear view camera detects vehicles in the detec tion zone, the Blind Spot Warning indicator illuminates.
• If the driver then activates the turn signal, a buzzer will sound twice and the Blind Spot Warning indicator will blink.
NOTE:
A buzzer sounds if the rear view camera has already detected vehicles when the driver activates the turn
signal. If a vehicle comes into the detection zone after t he driver activates the turn signal, then only the Blind
Spot Warning indicator blinks and no buzzer sounds.
BSW SYSTEM OPERATION DESCRIPTION
• Control unit enables BSW system.
• The control unit turns on the BSW system w hen the warning systems switch is turned ON.
• Rear view camera detects a vehicle in the adjacent l ane, and transmits the vehicle detection signal to control
unit.
• Control unit starts the control as follows, based on a vehicle detection signal, turn signal and dimmer signal transmitted from BCM via CAN communication:
- Blind Spot Warning indicator signal and Blind Spot Warning indicator dimmer signal transmission to rear view camera.
- Buzzer signal transmission to warning buzzer.
• Rear view camera transmits an indicator operation signal to the Blind Spot Warning indicator according to
Blind Spot Warning indicator signal and Blind Spot Warning indicator dimmer signal.

< PRECAUTION >[QR25DE]
PRECAUTIONS
• Be sure to connect rubber tubes properly afte
r work. A misconnected or disconnected rubber tube
may cause the MIL to light up due to the malfunction of the EVAP system or fuel injection system,
etc.
• Be sure to erase the unnecessary malfunction info rmation (repairs completed) from the ECM and
TCM (Transmission control module) before returning the vehicle to the customer.
General PrecautionsINFOID:0000000009462050
•Always use a 12 volt battery as power source.
• Do not attempt to disconnect battery cables while engine is
running.
• Before connecting or disconnecting the ECM harness con-
nector, turn ignition switch OFF and disconnect negative bat-
tery cable. Failure to do so may damage the ECM because
battery voltage is applied to ECM even if ignition switch is
turned OFF.
• Before removing parts, turn ig nition switch OFF and then dis-
connect battery ground cable.
• Do not disassemble ECM.
• If a battery cable is disconnected, the memory will return to
the ECM value.
The ECM will now start to self-control at its initial value.
Engine operation can vary slight ly when the terminal is dis-
connected. However, this is no t an indication of a malfunc-
tion. Do not replace parts b ecause of a slight variation.
• If the battery is disconnected, the following emission-related
diagnostic information will be lost within 24 hours.
- Diagnostic trouble codes
- 1st trip diagnostic trouble codes
- Freeze frame data
- 1st trip freeze frame data
- System readiness test (SRT) codes
- Test values
• When connecting or disconnect ing pin connectors into or
from ECM, take care not to damage pin terminals (bend or
break).
Make sure that there are not any bends or breaks on ECM pin
terminal, when connecting pin connectors.
• Securely connect ECM harness connectors.
A poor connection can cause an extremely high (surge) volt-
age to develop in coil and co ndenser, thus resulting in dam-
age to ICs.
• Keep engine control system harness at least 10 cm (4 in) away
from adjacent harness, to preven t engine control system mal-
functions due to receiving exter nal noise, degraded operation
of ICs, etc.
• Keep engine control system parts and harness dry.
• Before replacing ECM, perform ECM Terminals and Reference
Value inspection and make sure ECM functions properly.
Refer to EC-88, "Reference Value"
.
• Handle mass air flow sensor carefully to avoid damage.
• Do not clean mass air flow senso r with any type of detergent.
• Do not disassemble electric throttle control actuator.
• Even a slight leak in the ai r intake system can cause serious
incidents.
• Do not shock or jar the camshaft position sensor (PHASE),
crankshaft position sensor (POS).
