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.

AUTOMATIC DRIVE POSITIONERPFP:28491
System Description AIS002XB

The system automatically moves the driver seat to facilitate entry/exit to/from the vehicle. The automatic
drive positioner control unit can also store the optimum driving positions (driver seat, pedal position and
door mirror position) for 2 people. If the driver is changes, one-touch operation allows changing to the
other driving position.

The settings (ON/OFF) of the automatic sliding seat (Entry/Exiting operation) at entry/exit can be changed
as desired, using the display unit in the center of the instrument panel. The set content is transmitted by
CAN communication, from display unit (without NAVI) or display control unit (with NAVI) to driver seat con-
trol unit.

Using CONSULT-II, the seat slide amount at entry/exit setting can be changed.
MANUAL OPERATION
The driving position [seat position, steering wheel position (tilt, telescopic) and door mirror position] can be
adjusted with the power seat switch or ADP steering switch or door mirror remote control switch.
NOTE:

The seat can be manually operated with the ignition switch OFF.

The door mirrors can be manually operated with the ignition switch turned ACC or ON.
A U T O M AT I C O P E R AT I O N
NOTE:

Disconnecting the battery erases the stored memory.

After connecting the battery, insert the key into the ignition cylinder and turn the driver door switch ON (open) →OFF (close) →ON
(open), the Entry/ Exiting operation becomes possible.

After exiting operation is carried out, return operation can be operated.
NOTE:
During automatic operation, if the ignition switch is turned ON →START, the automatic operation is suspended. When the ignition switch
returns to ON, it resumes. Function Description
Memory switch operation The seat, steering and door mirror move to the stored driving position by pushing
memory switch (1 or 2).
Entry/Exiting function Exiting operation At exit, the seat moves backward and steering wheel moves forward/upward.
Entry operation
At entry, the seat and steering wheel returns from the exiting position to the previous
driving position.
Key fob interlock operation Perform memory operation, exiting operation and entry operation by pressing key fob
unlock button.
Auto operation temporary stop
conditions. When ignition switch turned to START during memory switch operation and return opera-
tion, memory switch operation and entry operation is stopped.
Auto operation stop conditions.

When the vehicle speed becomes 7 km/h (4 MPH) or higher.

When the setting switch, memory switch 1, or 2 are pressed.

When A/T selector lever is in any position other than P.

When the door mirror remote control switch is operated (when ignition switch turned to
ON or ACC).

When power seat switch turned ON.

When ADP steering switch turned ON (telescopic operation or tilt operation).

When door mirror operates (only memory switch operation).

When driver seat sliding Entry/Exiting setting is OFF (only entry/exiting operation).

When steering wheel tilt and telescopic Entry/Exiting setting is OFF (only entry/exiting
operation).

When the tilt and telescopic sensor malfunction is detected.

KEY FOB INTERLOCK OPERATION

Perform memory operation, exiting operation and entry operation by pressing key fob unlock button.
NOTE:

If steering wheel operation is cancelled, the system performs seat and mirror operation only.

If Entry/Exiting operation is cancelled, the system performs steering wheel operation and mirror operation
only.

If ignition switch turns ON in the middle of memory operation, the system does not perform exiting opera-
tion after memory operation.

If ignition switch turns ON in the middle of exiting operation, entry operation starts at that time.
FAIL - SAFE MO DE
When any manual and automatic operations are not performed, if any motor operations of seats or tilt of steer-
ing are detected for approx. 0.1 sec or more, status is judged “Output malfunction”. Motor operation will be
suspended automatically, and all automatic operations will be ineffective (in this case, the motor will not oper-
ate manually).
CANCEL OF FAIL-SAFE MODE

The mode is cancelled when the selector lever is shifted to P position from any other position.
