INTELLIGENT KEY INTERLOCK FUNCTION : System Description

INFOID:0000000009176533

• By associating Intelligent Key and automatic drive positioner system, the unlock operation of Intelligent Key

or driver side door request switch performs memory function and entry/exit assist function.

• Registration of Intelligent Key interlock function can register a different key ID to the driver seat control unit,

one by one, for memory switch 1 and 2. A total of 2 key IDs can be registered.

• When ignition switch is OFF, and door unlock operation is performed using Intelligent Key or driver side door

request switch, 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 ignition switch is operated from OFF to ACC, return operation sets seat sliding and

steering column tilt to a registered position.

NOTE:

• When another key ID is newly registered to a key switch to which a key ID is already registered, the previ-

ously registered key ID is overwritten and becomes unusable.

• When starter signal turns ON during return operation, the operation is interrupted, starter signal turns from

ON to OFF, and operation restarts.

OPERATION PROCEDURE

1. Unlock driver door by Intelligent Key or driver side door request switch.

2. Operation other than memory function of seat sliding is performed. Seat sliding and steering column tilt

perform exit assist operation.

3. Turn ignition switch ACC.

4. Driver seat and steering column will return from the exiting position to entry position. 

NOTE:

Further information for Intelligent Key interlock function. Refer to 

ADP-74, "INTELLIGENT KEY INTERLOCK

STORING : Description"

.

DIAGNOSIS SYSTEM (DRIVER SEAT CONTROL UNIT)

CONSULT Function (AUTO DRIVE POS.)

INFOID:0000000009176535

CAUTION:

After disconnecting the CONSULT vehicle interface (VI) from the data link connector, the ignition must

be cycled OFF 

→ ON (for at least 5 seconds) → OFF. If this step is not performed, the BCM may not go

to "sleep mode", potentially causing a discharged battery and a no-start condition.

The auto drive positioner system can be checked and diagnosed for component operation with CONSULT.
