Flow of electric steering lock unlocking control
<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.
•
Matching of certification results with KOS-ECU (Refer to Step <1> to <4> of power supply
changeover control.)
<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.
Flow of electric steering lock locking control
•
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.
