TCM receives the transmission range switch signal and then transmits the P/N position signal to BCM and
IPDM E/R.
BCM confirms the A/T shift selector position with the following 5 signals.
• P position signal from A/T shift selector (detention switch)
• P/N position signal from transmission range switch
• P position signal from IPDM E/R (CAN)
• P/N position signal from IPDM E/R (CAN)
• P/N position signal from TCM (CAN)
IPDM E/R confirms the A/T shift selector position with the following 3 signals.
• P position signal from A/T shift selector (detention switch)
• P/N position signal from transmission range switch
• P/N position signal from BCM (CAN)

INTELLIGENT KEY SYSTEM/ENGINE START FUNCTION : System Description

SYSTEM DESCRIPTION
• The engine start function of Intelligent Key system makes it possible to start and stop the engine without
using the key, based on the electronic ID verification. The electronic ID verification is performed between
BCM and Intelligent Key when the push-button ignition switch is pressed while the Intelligent Key is within
the detection area of inside key antenna.
NOTE:
The driver should carry the Intelligent Key at all times.
• Intelligent Key has 2 IDs (Intelligent Key ID and NATS ID). It can perform the door lock/unlock operation and
the push-button ignition switch operation when the registered Intelligent Key is carried.
• When Intelligent Key battery is discharged, engine can be started by operating push-button ignition switch
after contacting Intelligent Key backside to push-button ignition switch. At that time, NATS ID verification is
performed.
• If the ID is successfully verified, when push-button ignition switch is pressed, steering lock is released and
the engine can be started.

• Up to 4 Intelligent Keys can be registered (Including the standard Intelligent Key) upon request from the cus-
tomer.
NOTE:
Refer to
DLK-14, "INTELLIGENT KEY SYSTEM : System Description"
for any functions other than engine
start function of Intelligent Key system.
PRECAUTIONS FOR INTELLIGENT KEY SYSTEM
The transponder (the chip for NATS ID verification) is integrated into the Intelligent Key. (For the con-
ventional models, it is integrated into the mechanical key.) Therefore, ID verification cannot be per-
formed by mechanical key only.
In that case, NATS ID verification can be performed when Intelligent Key backside is contacted to
push-button ignition switch. If verification result is OK, engine can be started.
OPERATION WHEN INTELLIGENT KEY IS CARRIED
1.
When the push-button ignition switch is pressed, the BCM activates the inside key antenna and transmits
the request signal to the Intelligent Key.
2.
The Intelligent Key receives the request signal and transmits the Intelligent Key ID signal to the BCM.
3.
BCM receives the Intelligent Key ID signal via remote keyless entry receiver and verifies it with the regis-
tered ID.
4.
BCM transmits the unlock signal to steering lock unit and IPDM E/R if the verification results are OK.
5.
IPDM E/R turns the steering lock relay ON and supplies power supply to the steering lock unit.
6.
The steering lock releases.
7.
BCM transmits the power supply stop signal to IPDM E/R when detecting that the steering lock is in the
unlock condition.
8.
IPDM E/R turns the steering lock relay OFF and stops power supply to the steering lock unit.
9.
BCM turns ACC relay ON and transmits the ignition power supply ON signal to IPDM E/R.
10. IPDM E/R turns the ignition relay ON and starts the ignition power supply.
11. BCM detects that the selector lever position and brake pedal operating condition.
12. BCM transmits the starter request signal to IPDM E/R and turns the starter relay in IPDM E/R ON if BCM
judges that the engine start condition is satisfied.
13. IPDM E/R turns the starter control relay ON when receiving the starter request signal.
14. Power supply is supplied through the starter relay and the starter control relay to operate the starter motor.
CAUTION:
If a malfunction is detected in the Intelligent Key system, the “KEY” warning lamp in the combina-
tion meter illuminates. At that time, the engine cannot be started.
15. When BCM receives feedback signal from ECM indicating that the engine is started, the BCM transmits a
stop signal to IPDM E/R and stops cranking by turning OFF the starter motor relay. (If engine start is
unsuccessful, cranking stops automatically within 5 seconds.)
CAUTION:
When the Intelligent Key is carried outside of the vehicle (inside key antenna detection area) while
the power supply is in the ACC or ON position, even if the engine start condition* is satisfied, the
engine cannot be started.
*: For the engine start condition, refer to “POWER SUPPLY POSITION CHANGE TABLE BY PUSH-BUTTON
IGNITION SWITCH OPERATION”.
OPERATION RANGE
Engine can be started when Intelligent Key is inside the vehicle. However, sometimes engine may not start
when Intelligent Key is on instrument panel or in glove box.
ENGINE START OPERATION WHEN INTELLIGENT KEY IS CONTACTED TO PUSH-BUTTON IG-
NITION SWITCH
When Intelligent Key battery is discharged, NATS ID verification between transponder in Intelligent Key and
BCM is performed when Intelligent Key backside is contacted to push-button ignition switch. If the verification
result is OK, engine can be started.
STEERING LOCK OPERATION
Steering is locked by steering lock unit when any of the following conditions are met.

SYSTEM
• When ignition switch is in the OFF position, selector lever is in the P position, and any of the following condi-
tions are met.
- Closing door
- Opening door
- Door is locked using door request switch
- Door is locked using Intelligent Key
• When BCM power consumption control system is released by meeting any of the following conditions.

POWER SUPPLY POSITION CHANGE TABLE BY PUSH-BUTTON IGNITION SWITCH OPERA-
TION
The power supply position changing operation can be performed with the following operations.
NOTE:
• When an Intelligent Key is within the detection area of inside key antenna and when Intelligent Key backside
is contacted to push-button ignition switch, it is equivalent to the operations below.
• When starting the engine, the BCM monitors under the engine start conditions,
- Brake pedal operating condition
- Selector lever position
- Vehicle speed
Vehicle speed: less than 4 km/h (2.5 MPH)
Vehicle speed: 4 km/h (2.5 MPH) or more
Emergency stop operation
• Press and hold the push-button ignition switch for 2 seconds or more.
• Press the push-button ignition switch 3 times or more within 1.5 seconds.
