to CPU of IPDM E/R.
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.
Ground is supplied

to IPDM E/R terminals 38, 50 and 60

from grounds E21, E50 and E51.
With the ignition switch in the START position, and provided that the IPDM E/R receives a starter relay ON sig-
nal from the CAN lines, the IPDM E/R is energized and power is supplied

from ignition switch terminal 5

to IPDM E/R terminal 4 and

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 SYSTEMPFP:23100
System DescriptionAKS0079I
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. 33, located in the fuse and fusible link block)

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 charging circuit is protected by the 120A fusible link (VK45DE and VQ35DE AWD).
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 7 for the charge warning lamp.
Ground is supplied

to combination meter terminal 2

through alternator terminal 3 (“L” terminal)

to alternator terminal 2 (“E” terminal) (VK45DE) or through case ground (VQ35DE)

through ground E304 (VK45DE).
With power and ground supplied, the charge warning lamp will illuminate. When the alternator is providing suf-
ficient 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.
MALFUNCTION INDICATOR
The IC regulator warning function activates to illuminate charge warning lamp, if any of the following symp-
toms occur while alternator is operating:

Excessive voltage is produced.

No voltage is produced.
