SYSTEM OPERATION

KEYLESS OPERATION SYSTEM (KOS)

42B-21

Electric steering lock locking/unlocking control (Operation description)

Flow of power supply changeover control

<1>

Under the power OFF status, operate the engine switch without depressing the brake pedal.

<2>

By the operation of engine switch, OSS-ECU sends KOS-ECU the certification request via CAN,
and at the same time, supplies the electric steering lock unit power to the electric steering lock.

<3>

In accordance with the certification request from OSS-ECU, KOS-ECU performs the certification
communication with the keyless operation key.

<4>

KOS-ECU sends the key certification result to OSS-ECU via CAN. OSS-ECU compares its
certification result with the KOS-ECU certification result, and goes to <5> when the results agree
with each other.

<5>

OSS-ECU performs the certification communication with the electric steering lock via LIN (local
LIN). The electric steering lock compares the certification result with that of OSS-ECU, and
unlocks the steering lock when the results agree with each other.

<6>

After the certification communication with the electric steering lock, OSS-ECU sends the ACC
output to ETACS-ECU. Then, ETACS-ECU drives the internal ACC relay to turn the power to
ACC.

<7>

With the power supply set to ACC, when the engine switch is operated again without depressing
the brake pedal <CVT vehicle>, OSS-ECU sends the IG1 output. Then, the current is supplied to
the IG1 relay in ETACS-ECU, thus driving the IG1 relay and turning the power ON. (At this time,
OSS-ECU also communicates with engine-ECU to certify the engine start.)

<8>

With the power supply set to ON, when the engine switch is operated again without depressing
the brake pedal, the power of the CVT vehicle is turned OFF when the selector lever is in the P
position, or the power is turned to ACC when in other than the P position. When the vehicle
speed information, which is received via CAN, cannot be received or when the vehicle speed is 3
km/h or more, any standard engine switch operations will not be accepted. However, the power

can be turned to ACC by the emergency stop operation

NOTE:

: The emergency stop operation refers to the operation to press and hold the engine

switch for 3 seconds or longer, or to repeatedly press the engine switch 3 times or more within 1
second. After the emergency stop operation, OSS-ECU will not accept the engine switch
operation for 2 seconds.

Matching of certification results with KOS-ECU (Refer to Step <1> to <4> of power supply

<3>

OSS-ECU performs the certification communication with the electric steering lock via LIN (local
LIN). The electric steering lock compares the certification result with that of OSS-ECU, and
unlocks the electric steering lock by driving the internal actuator when the results agree with each
other.

<4>

After the electric steering lock is unlocked, OSS-ECU stops the supplying of electric steering lock
unit power to the electric steering lock. (Subsequently, OSS-ECU sends the ACC output to
ETACS-ECU. Then, ETACS-ECU drives the internal ACC relay to turn the power to ACC.)

<5>

After the engine is started, KOS-ECU stops the actuator driving permission signal for the electric
steering lock.

Unlock status of electric steering lock

<1>

KOS-ECU supplies the actuator driving power to the electric steering lock.

<2>

With the power supply set to OFF, OSS-ECU receives the door status change (excluding tailgate)
from ETACS-ECU via CAN. Using the door status change from "Open to Close to Open" as a

trigger

, OSS-ECU supplies the electric steering lock unit power to the electric steering lock, and

then performs the certification communication via LIN (local LIN). The electric steering lock
compares the certification result with that of OSS-ECU, and locks the steering lock by driving the
internal actuator when the results agree with each other.

NOTE:

: The trigger also includes the operation of lock/unlock button on keyless operation key

as well as the door locking/unlocking by the operation of keyless operation switch.

<3>

After the electric steering lock is locked, OSS-ECU stops the supplying of electric steering lock
unit power to the electric steering lock.

KOS WARNING AND WARNING INDICATOR LIST

When the KOS fails or operates improperly, the
KOS-ECU warns the driver of this by setting off the
outer buzzer and by displaying the keyless operation
warning by the indicator lamp in the combination
meter.

<2>

At the same time with the transmission of certification request to engine-ECU via CAN, OSS-ECU
also sends the starter output to engine-ECU.

<3>

Engine-ECU supplies current to the starter relay to perform cranking. Also, engine-ECU
compares its own certification result with the OSS-ECU certification result, and starts the engine
when the results agree with each other. (If the certification results do not agree with each other,
engine-ECU stops the supplying of current to the starter relay and injector. Also, OSS-ECU stops
the starter output.)

<4>

After the engine start is complete, OSS-ECU stops the starter output.
