INPUT SIGNAL AND OUTPUT SIGNAL

Several types of signal are transmitted from the following units to the driver seat control unit via CAN communication:

Component	Signal
ABS actuator and electric unit (control unit)	Vehicle speed signal
Combination meter	Vehicle speed signal
BCM	Ignition switch signal Key ID signal
TCM	Shift position signal
Chassis control module	Key link signal Log-in permit signal
AV control unit	User information signal

DESCRIPTION

When push-button ignition switch is OFF, and door unlock operation is performed using Intelligent Key or driver side door request switch or one touch unlock sensor, driver seat automatically adjusts to a driving position other than seat sliding. Seat sliding and steering column tilt perform return operation and are set to standby status.
In standby status, when push-button ignition switch is operated from OFF to ACC, return operation sets seat sliding and steering column tilt to a registered position.

NOTE:

When starter signal turns ON during return operation, the operation is interrupted, starter signal turns from ON to OFF, and operation restarts.
