INTEGRATED COLOR DISPLAY SYSTEMPFP:28090
System DescriptionBKS0027J
For system operation information, refer to Owner's Manual.
INTEGRATED COLOR DISPLAY SYSTEM

Each control unit that comprises the system is connected with a communication circuit. It transmits/
receives data signals including request signals and response signals, and controls the system.

The display control unit transmits/receives data signals to/from each control unit with CAN communica-
tion. It performs an arithmetical operation on fuel information values by using data obtained from the con-
trol units, and then displays the calculated values on the screen.

The display control unit receives vehicle speed signals that are transmitted from the unified meter and A/
C amp., performs an arithmetical operation on drive information values, and then displays the calculated
values on the screen.

The images displayed on the monitor screen contain display control unit-generated RGB images, and rear
view images transmitted from the rear view camera control unit.

The display control unit controls image switching and image quality adjustments by communications with
the display.
REAR VIEW MONITOR

A rear view monitor was set to vehicle, which can check rearward on screen when backing up the vehicle.

For easier recognition of the vehicle width and the distance to the objects, the guide lines of distances and
rear are combined with the rear view image.

Image quality of the rear view image and of the RGB image can be adjusted separately.

SQUEAK AND RATTLE TROUBLE DIAGNOSES

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.
