TRUNK
Trunk noises are often caused by a loose jack or loose items put into the trunk by the owner.
In addition look for:
1. Trunk lid dumpers out of adjustment
2. Trunk lid striker out of adjustment
3. Trunk lid torsion bars knocking together
4. A loose license plate or bracket
Most of these incidents can be repaired by adjusting, securing or insulating the item(s) or component(s) caus-
ing the noise.
SUNROOF/HEADLINING
Noises in the sunroof/headlining area can often be traced to one of the following:
1. Sunroof lid, rail, linkage or seals making a rattle or light knocking noise
2. Sunvisor shaft shaking in the holder
3. Front or rear windshield touching headlining and squeaking
Again, pressing on the components to stop the noise while duplicating the conditions can isolate most of these
incidents. Repairs usually consist of insulating with felt cloth tape.
SEATS
When isolating seat noise it's important to note the position the seat is in and the load placed on the seat when
the noise is present. These conditions should be duplicated when verifying and isolating the cause of the
noise.
Cause of seat noise include:
1. Headrest rods and holder
2. A squeak between the seat pad cushion and frame
3. Rear seatback lock and bracket
These noises can be isolated by moving or pressing on the suspected components while duplicating the con-
ditions under which the noise occurs. Most of these incidents can be repaired by repositioning the component
or applying urethane tape to the contact area.
UNDERHOOD
Some interior noise may be caused by components under the hood or on the engine wall. The noise is then
transmitted into the passenger compartment.
Causes of transmitted underhood noise include:
1. Any component mounted to the engine wall
2. Components that pass through the engine wall
3. Engine wall mounts and connectors
4. Loose radiator mounting pins
5. Hood bumpers out of adjustment
6. Hood striker out of adjustment
These noises can be difficult to isolate since they cannot be reached from the interior of the vehicle. The best
method is to secure, move or insulate one component at a time and test drive the vehicle. Also, engine RPM
or load can be changed to isolate the noise. Repairs can usually be made by moving, adjusting, securing, or
insulating the component causing the noise.

AUTOMATIC DRIVE POSITIONER
AUTOMATIC DRIVE POSITIONERPFP:28491
System Description BIS0012G
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) for 2 people. If the
driver is changes, one-touch operation allows changing to the other driving position.
Using CONSULT-II, the seat slide amount at entry/exit setting can be changed.
MANUAL OPERATION
The driving position (seat position) can be adjusted with the power seat switch.
NOTE:
The seat can be manually operated with the ignition switch OFF.
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, entry 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 move to the stored driving position by pushing memory switch (1 or 2).
Entry/Exiting functionExiting operation At exit, the seat moves backward.
Entry operation At entry, the seat returns from the exiting position to the previous driving position.
Keyfob interlock operation Perform memory operation and exiting 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 or CVT selector lever is in any position other than P.

MEMORY STORING AND KEYFOB INTERLOCK STORING
Store the 2 driving positions and shifts to the stored driving position with the memory switch.
Keyfob interlock function is set simultaneously with setting driving position memory. It can set driving posi-
tion to memory position.
NOTE:
If another keyfob interlock function setting is performed by same key, newly registered setting is valid.
If new memory string is performed to memory switch that already set keyfob interlock function, keyfob
interlock function setting is reset.
If key does not set previously, keyfob interlock function cannot set.

KEYFOB INTERLOCK OPERATION
Perform memory operation, exiting operation and entry operation by pressing keyfob unlock button.
NOTE:
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 MODE
When any manual and automatic operations are not performed, if any motor operations of seats are detected
for approx. 0.1 sec or more, status is judged “Output malfunction”. Motor operation will be suspended auto-
matically, and all automatic operations will be ineffective (in this case, the motor will not operate 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 DescriptionBIS0012I
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.
