ler button operation, hazard lamps flash and horn sounds.
ENGINE STARTUP FUNCTION
Operation Description
When ignition knob is pressed, Intelligent Key unit sends request signal from inside key antenna, key-ID ver- ification is conducted with Intelligent Key using two-wa y communication, and if verification is successful, an
ignition rotation prohibition latch release signal is sent to steering lock unit. Steering lock unit releases igni-
tion knob rotation prohibition latch. (Ignition knob can now be turned.)
When it becomes possible to rotate the ignition knob, “KEY” warning lamp in combination meter lights up green to notify driver that ignition knob can be turned.
NOTE:
When it becomes impossible to rotate the ignition knob, “KEY” warning lamp in combination meter lights up
red.
When key-ID verification is successful and ignition knob switch is in the ON state, Intelligent Key unit uses CAN communication to send engine start permission signal to BCM.
When BCM receives engine start permission signal, it uses CAN communication to sent starter request sig-
nal to IPDM E/R so that the engine will start when ignition knob is rotated to START position.
Operation Range
Engine can be started when Intelligent Key is in the v ehicle. However, sometimes engine might not start when
Intelligent Key is on instrument panel, rear parcel shelf, or in glove box.
NOTE:
luggage room can enable detection of Intelligent Key by a CONSULT-III function. Refer to BL-104, "
CON-
SULT-III Application Item".

CAN Communication System DescriptionINFOID:0000000001327838
CAN (Controller Area Network) is a serial communication li ne 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.

LANE DEPARTURE WARNING SYSTEM
Precaution for Lane Depa rture Warning (LDW) systemINFOID:0000000001328492
WARNING:
Lane Departure Warning (LDW) is only a warning d evice to inform the driver of an unintended lane
departure. It will not steer the vehicle or prevent loss of control. It is the driver's responsibility to stay
alert, drive safely, keep the vehicle in the traveling lane, and be in control of the vehicle at all times.
LDW system does not operate u nder the following conditions:
- At speeds below approx. 72 km/h (45 MPH).
- If it cannot detect lane markers.
LDW system may not function proper ly under the following conditions:
- On roads where a water puddle, dirt or snow is covering the lane markers.
- On roads where the lane markers are faded or are not painted clearly.
- On roads where the lane markers are painted yellow.
LDW system may not monitor the lane markers in certain road, weather or driving conditions.
- On roads where there are sharp curves.
- Where the traveling lane merges or separates.
- On roads where the discontinued lane marker s are present, such as near tollgates, etc.
- On roads where there are not general lane markers.
- On roads where the lane width is too narrow.
- During bad weather (rain, fog, snow, etc.).
- When strong light (for example, at sunrise or sunse t) is directly shining on the front of the vehicle.
- When entering or exiting a tunnel wher e sudden changes in brightness occur.
- When traveling close to the vehicle in front of you, which causes obstruction of the camera unit
range.
- When the vehicle's traveling direction does not align with the lane marker.
- When rain, snow or dirt adhere to the windshield in front of the camera unit.
Excessive noise interferes with warning system ch ime sound and the chime may not be heard.

The above information can be checked usi ng procedures listed in the table below.
×: Applicable —: Not applicable
*: When DTC and 1st trip DTC simultaneously appear on the display, they cannot be clearly distinguished from each other.
The malfunction indicator lamp (MIL) on the instrument panel lights up when the same malfunction is detected
in two consecutive trips (Two trip detection logic) , or when the ECM enters fail-safe mode. (Refer to EC-95,
"Fail-Safe Chart".)
Two Trip Detection LogicINFOID:0000000001325915
When a malfunction is detected for the 1st time, 1st trip DTC and 1st trip Freeze Frame data are stored in the
ECM memory. The MIL will not light up at this stage. <1st trip>
If the same malfunction is detected again during the next drive, the DTC and Freeze Frame data are stored in
the ECM memory, and the MIL lights up. The MIL lights up at the same time when the DTC is stored. <2nd
trip> The “trip” in the “Two Trip Detection Logic” m eans a driving mode in which self-diagnosis is performed
during vehicle operation. Specific on board diagnostic item s will cause the ECM to light up or blink the MIL,
and store DTC and Freeze Frame data, even in the 1st trip, as shown below.
