Fuse EKS00GKH

If fuse is blown, be sure to eliminate cause of incident before
installing new fuse.

Use fuse of specified rating. Never use fuse of more than speci-
fied rating.

Do not partially install fuse; always insert it into fuse holder prop-
erly.

Remove fuse for “ELECTRICAL PARTS (BAT)” if vehicle is not
used for a long period of time.
Fusible Link EKS00GKI
A melted fusible link can be detected either by visual inspection or by feeling with finger tip. If its condition is
questionable, use circuit tester or test lamp.
CAUTION:

If fusible link should melt, it is possible that critical circuit (power supply or large current carrying
circuit) is shorted. In such a case, carefully check and eliminate cause of incident.

Never wrap outside of fusible link with vinyl tape.

Never let fusible link touch any other wiring harness, vinyl or rubber parts.
Circuit Breaker (Built Into BCM)EKS00GKJ
For example, when current is 30A, the circuit is broken within 8 to 20
seconds.
A circuit breaker is used for the following systems:

Power windows

Power door locks

Remote keyless entry system

Power sunroof

Rear window wiper

Revision: November 2009 2006 QX56
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 bumpers 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. Sun visor shaft shaking in the holder
3. Front or rear windshield touching headliner 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.
OVERHEAD CONSOLE (FRONT AND REAR)
Overhead console noises are often caused by the console panel clips not being engaged correctly. Most of
these incidents are repaired by pushing up on the console at the clip locations until the clips engage.
In addition look for:
1. Loose harness or harness connectors.
2. Front console map/reading lamp lens loose.
3. Loose screws at console attachment points.
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 compartment.
Causes of transmitted underhood noise include:
1. Any component installed to the engine wall
2. Components that pass through the engine wall
3. Engine wall mounts and connectors
4. Loose radiator installation 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.

OUTLINE
Electric sunroof system consists of

Front door switches

Sunroof switch

Sunroof motor assembly

BCM (body control module)
BCM supplies power to the sunroof motor. Sunroof operation depends on sunroof switch condition.
OPERATION
Power is supplied at all times

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

to BCM terminal 70, and

through BCM terminal 69

to sunroof motor assembly terminal 5.
With ignition switch in ON or START position, power is supplied

through 10A fuse (No. 59, located in the fuse and relay box)

to BCM terminal 38.
Ground is supplied

to BCM terminal 67 and

to sunroof motor assembly terminal 7

through grounds M57, M61 and M79.

TILT UP OPERATION
When the tilt switch is operated for tilt up, ground is supplied

to sunroof motor assembly terminal 4

through sunroof switch terminal 4

through sunroof switch terminal 2

through sunroof motor assembly terminal 8

through grounds M57, M61 and M79.
Then, the sunroof will tilt up.
TILT DOWN OPERATION
When the tilt switch is operated for tilt down, ground is supplied

to sunroof motor assembly terminal 10

through sunroof switch terminal 6

through sunroof switch terminal 2

through sunroof motor assembly terminal 8

through grounds M57, M61 and M79.
Then, the sunroof will tilt down.
SLIDE OPEN OPERATION
When the switch is operated for slide open, ground is supplied

to sunroof motor assembly terminal 9

through sunroof switch terminal 3

through sunroof switch terminal 2

through sunroof motor assembly terminal 8

through grounds M57, M61 and M79.
Then, the sunroof will slide open.
SLIDE CLOSE OPERATION
When the switch is operated for slide close, ground is supplied

to sunroof motor assembly terminal 3

through sunroof switch terminal 1

through sunroof switch terminal 2

through sunroof motor assembly terminal 8

through grounds M57, M61 and M79.
Then, the sunroof will slide closed.
RETAINED POWER OPERATION
When the ignition switch is turned to OFF position from ON or START position, power is supplied for 45 sec-
onds.
The retained power operation is canceled when the driver or passenger side door is opened.
RAP signal period can be changed by CONSULT-II. Refer to RF-16, "
CONSULT-II Function (BCM)" .
MEMORY RESET PROCEDURE
To reset the sunroof motor memory from any sunroof position (full open, partially open, closed, partially
vented, and vented), push and hold the sunroof tilt switch in the forward (DOWN) position until the sunroof is
fully closed. After it has closed all the way, push and hold the tilt switch forward (DOWN) for more than 2 sec-
onds to re-establish the motor preset position. The sunroof should now operate normally.
INTERRUPTION DETECTION FUNCTION
The CPU (central processing unit) monitors the sunroof motor operation and the sunroof position (fully-closed
or other) by the signals from the sunroof motor.
When sunroof motor detects an interruption during the following sliding close operations, sunroof switch con-
trols the motor for open and the sunroof will operate until it reaches full open position.

automatic close operation when ignition switch is in the ON position.
