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.
