SQUEAK AND RATTLE TROUBLE DIAGNOSIS
Revision: 2004 November 2004 FX35/FX45
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. The 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. The 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 room.
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 POSITIONERPFP:28491
System Description AIS002XB

The system automatically moves the driver seat to facilitate entry/exit to/from the vehicle. The automatic
driver 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.
MEMORY STORING AND KEY FOB INTERLOCK STORING

Store the 2 driving positions and shifts to the stored driving position with the memory switch.
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 functionExiting operation At exit, the seat moves backward and steering wheel moves forward/upward.
Entry operationAt entry, the seat and steering wheel returns from the exiting position to the previous
driving position.
Key fob interlock operationPerform 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.

NOTE:
The driver's seat position and steering adjustment functions (see the following table) operate simultaneously in
the order of priority.
*: In conjunction with sliding the seat, the door mirrors are positioned.
ENTRY OPERATION
When the seat are on the exiting positions, the following operation moves the seat to the previous position
before the exiting operation.

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.
