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.

System DescriptionBIS0010S
Power supplied at all time

through 50A fusible link (letter M , located in the fuse and fusible link box)

to BCM terminal 55

through 15A fuse [No.17, located in the fuse block (J/B)]

to BCM terminal 42

through BCM terminal 54

to sunroof motor assembly terminal 6.
With ignition switch ON or START position,
Power is supplied

through 10A fuse [No.1, located in the fuse block (J/B)]

to BCM terminal 38

through BCM terminal 53

to sunroof motor assembly terminal 3.
Ground is supplied

to BCM terminal 52

to sunroof motor assembly terminal 2

through body grounds M71, M72.
TILT UP / SLIDE CLOSE OPERATION
When tilt up / slide close switch is pressed,
Ground is supplied

to sunroof motor assembly terminal 5

through sunroof switch terminal 3

through sunroof switch terminal 2

through body grounds M71, M72.
Then, the sunroof tilt up / slide close.
TILT DOWN / SLIDE OPEN OPERATION
When tilt down / slide open switch is pressed,
Ground is supplied

to sunroof motor assembly terminal 1

through sunroof switch terminal 1

through sunroof switch terminal 2

through body grounds M71, M72.
Then, the sunroof tilt down / slide open.
AUTO OPERATION
The power sunroof AUTO feature makes it possible to slide open and slide close or tilt up and tilt down the
sunroof without holding the sunroof switch in the slide open or slide close / tilt up or tilt down position.
TIMER FUNCTION
When the ignition switch is turned to OFF position from ON or START position, timer operates for 15 minutes.
Sunroof can be operated for 15 minutes.
Timer operation is canceled when one of the following conditions is satisfied.

ignition switch : OFF→ ON

front door switch (driver side) : ON (Open)→OFF (Closed)
ANTI-PINCH FUNCTION
The CPU of sunroof motor monitors the sunroof motor operation and the sunroof position (fully-closed or
other) by the signals from sunroof motor.
When sunroof motor detects an interruption during the following slide close and tilt down operation, sunroof
motor controls the sunroof motor for open and the sunroof will operate until full up position (during tilt down
operation) or 125 mm (4.92 in) or more in an open direction (during slide close operation)

RF-12
SUNROOF

The operation condition is the following.

automatic close operation and tilt down when ignition switch is in the ON position

automatic close operation and tilt down during retained power operation.
MEMORY RESET PROCEDURE
1. Please observe the following instructions while confirming the sunroof operation.
NOTE:
Do not disconnect the electronic power while the sunroof is operating or within 5 seconds after the sunroof
stops.
2. Initialization of system should be conducted after the following conditions.

When the battery is out or connector is disconnected while sunroof is operating or within 5 seconds
after sunroof stops.

When the sunroof motor is changed.

When the sunroof does not operate normally. (Incomplete initialization conditions)
INITIALIZATION PROCEDURE
If the sunroof does not close or open automatically, use the following procedure to return sunroof operation to
normal.
1. Press and hold the switch to the CLOSE/UP side for approximately 10 seconds.
2. The glass lid will move toward tilt up direction and will be stopped mechanically, and then it will be auto-
matically fully closed. Then glass lid will be automatically operated in sequence of “tilt up” → “tilt down” →
“slide open” → “slide close”. (Keep pressing the switch during this operation)
3. After the glass lid stops, release the switch after 5 seconds.
4. If sunroof switch operates normally, this initialization is done.
