INTELLIGENT KEY SYSTEM/ENGINE START FUNCTION
Revision: 2006 January2006 M35/M45
System DescriptionNIS001Y8
The engine start function of Intelligent Key system is a system that makes it possible to start and stop the
engine without removing the key. It verifies the electronic ID using two-way communications when press-
ing the push-button ignition switch while carrying the Intelligent Key, which operates based on the results
of electronic ID verification for Intelligent Key using two-way communications between the Intelligent Key
and the vehicle (Intelligent Key unit).
NOTE:
The driver should always carry the intelligent key at all times.
Intelligent Key has 2 IDs (for Intelligent Key and for immobilizer). It can perform the door lock/unlock oper-
ation and the push-button ignition switch operation when carrying the registered Intelligent Key.
When the Intelligent Key battery is discharged, it can be used as emergency by inserting the Intelligent
Key to the key slot. At that time, perform the immobilizer ID verification. If it is used when carrying the
Intelligent Key, perform the Intelligent Key ID verification.
If the ID is successfully verified, and when push-button ignition switch is pressed, steering lock will be
released and initiating the engine will be possible.
If the door lock/unlock operation is performed when the Intelligent Key battery is discharged, all doors
lock/unlock can be performed by operating the driver door key cylinder using the mechanical key set into
the Intelligent Key.
Intelligent Key can be registered up to 4 keys (Including the standard Intelligent Key) on request from the
owner.
NOTE:
Refer to BL-44, "INTELLIGENT KEY SYSTEM" for any functions other than engine start function of
Intelligent Key system.

System DiagramNFS000Q5
FunctionNFS000Q6
ABS
Anti-Lock Brake System is a function that detects wheel revolution while braking, electronically controls
braking force, and prevents wheel locking during sudden braking. It improves handling stability and
maneuverability for avoiding obstacles.
Electrical system diagnosis by CONSULT-II is available.
EBD
Electronic Brake force Distribution is a following function. ABS actuator and electric unit (control unit)
detects subtle slippages between the front and rear wheels during braking. Then it electronically controls
the rear braking force (brake fluid pressure) to reducing and reduces rear wheel slippage. Accordingly it
improves vehicle stability.
Electrical system diagnosis by CONSULT-II is available.
TCS
Traction Control System is a function that electronically controls engine torque, brake fluid pressure and
A/T gear position to ensure the optimum slippage ratio at drive wheels by computing wheel speed signals
