ground.
OK or NG
OK >> GO TO 3.
NG >> Check the following.

Harness for open between alternator and fusible link
(VK45DE and VQ35DE AWD)

Harness for open between alternator and battery
(VQ35DE 2WD)
3. CHECK “B” TERMINAL CONNECTION (VOLTAGE DROP TEST)
1. Start engine.
2. When engine running at idle and warm, check voltage between alternator “B” terminal E307 terminal 1 and battery positive ter-
minal.
OK or NG
OK >> Go to SC-29, "WORK FLOW" .
NG >> Check harness between battery and alternator for poor continuity.

AUTOMATIC DRIVE POSITIONERPFP:28491
System Description NIS001UO

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, steering wheel posi-
tion (tilt, telescopic) 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 control unit to driver seat control unit.

Using CONSULT-II, the seat slide and steering wheel 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.
keyfob interlock operation Perform memory operation, exiting operation and entry operation by pressing keyfob
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.

KEYFOB INTERLOCK OPERATION

Perform memory operation, exiting operation and entry operation by pressing keyfob 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.

CAN Communication System DescriptionNIS001UQ
CAN (Controller Area Network) is a serial communication line for real time application. It is an on-vehicle mul-
tiplex communication line with high data communication speed and excellent error detection ability. Many elec-
tronic control units are equipped onto a vehicle, and each control unit shares information and links with other
control units during operation (not independent). In CAN communication, control units are connected with 2
communication lines (CAN H line, CAN L line) allowing a high rate of information transmission with less wiring.
Each control unit transmits/receives data but selectively reads required data only.
