System DescriptionNHS0007Y

Pre-crash seat belt system is adapted to front seat belts RH/LH.

When the pre-crash seat belt control unit judges the emergency braking operation, it gives the sense of
security by the motor built into the pre-crash seat belt retracting the shoulder belt and suppressing the
crew's posture change. Also, it eases the damage of the collision.

STARTING SYSTEM
Revision: 2007 April2007 M35/M45
STARTING SYSTEMPFP:23300
System Description NKS005C2
Power is supplied at all times

through 15A fuse (No. 78, located in the IPDM E/R)

to CPU of IPDM E/R,

through 15A fuse (No. 71, located in the IPDM E/R)

to CPU of IPDM E/R.
Ground is supplied

to IPDM E/R terminals 38 and 51

from grounds E22 and E43.
When the selector lever in the P or N position, power is supplied

from TCM, and through A/T assembly terminal 9

to IPDM E/R terminal 53.
And then provided that IPDM E/R receives a starter relay ON signal with CAN communication, starter relay is
energized.
With the ignition switch in the START position, power is supplied

through IPDM E/R terminal 3

to starter motor terminal 1.
The starter motor plunger closes and provides a closed circuit between the battery and starter motor. The
starter motor is grounded to the engine block. With power and ground supplied, cranking occurs and the
engine starts.

CHARGING SYSTEM
Revision: 2007 April2007 M35/M45
CHARGING SYSTEMPFP:23100
System Description NKS005BX
DESCRIPTION
The alternator provides DC voltage to operate the vehicle's electrical system and to keep the battery charged.
The voltage output is controlled by the IC regulator.
Power is supplied at all times

through 10A fuse [No. 36, located in the fuse, fusible link and relay block (J/B)]

to alternator terminal 4 (“S” terminal).
“B” terminal supplies power to charge the battery and operate the vehicle's electrical system. Output voltage is
controlled by the IC regulator at terminal 4 (“S” terminal) detecting the input voltage.
The alternator is grounded to the engine block.
With the ignition switch in the ON or START position, power is supplied

through 10A fuse [No. 14, located in the fuse block (J/B)]

to combination meter terminal 12 for the charge warning lamp.
Ground is supplied at signal

to combination meter terminal 22

through alternator terminal 3 (“L” terminal).
Then power and ground are supplied, the charge warning lamp will illuminate.
When the alternator is providing sufficient voltage with the engine running, the ground is opened and the
charge warning lamp will go off.
If the charge warning lamp illuminates with the engine running, a malfunction is indicated.
Ground is supplied

to alternator terminal 2 (“E” terminal)

through grounds E222, E223 and E224. (VQ35DE)

through ground E212. (VK45DE)
MALFUNCTION INDICATOR
The IC regulator warning function activates to illuminate the charge warning lamp, if any of the following symp-
toms occur while alternator is operating:

Excessive voltage is produced.

No voltage is produced.
