This system has the following functions: manual slide
open and close; auto slide open and close; manual tilt up
and down; auto tilt up and down; jam protection; and key
off operation.
2.FUNCTION OF MAIN COMPONENT
Sliding roof ECU controls sliding roof motor to rotate forward and
backward, which tilts or slides sliding roof glass.
Output of operation signals from built-in sliding roof switch to sliding
roof ECU is handled by overhead junction block.
3.SYSTEM OPERATION
The sliding roof has the following features:
This function causes sliding roof to open (or close) when OPEN/
CLOSE switch is pressed for a maximum of 0.3 seconds. Sliding roof
stops as soon as the switch is released.
This function causes sliding roof to fully open (or close) when OPEN/
CLOSE switch is pressed for a minimum of 0.3 seconds.
This function causes sliding roof to tilt up (or tilt down) when UP/
DOWN switch is pressed for a maximum of 0.3 seconds.
This function enables sliding roof to tilt up (or down) when UP/DOWN
switch is pressed for a minimum of 0.3 seconds.
The jam protection function automatically stops sliding roof, or stops
sliding roof and makes it open halfway (or fully tilted up) if a foreign
object gets jammed in sliding roof during auto close operation (or auto
tilt down operation).
Key off operation function makes it possible to operate sliding roof for
approximately 43 seconds after ignition switch is turned off, if front
doors are not opened.

INITIALIZATION
1.INITIALIZE SLIDING ROOF DRIVE GEAR SUB-
ASSEMBLY
NOTICE:
When replacing the sliding roof drive gear, the
sliding roof drive gear requires initialization. If a
reset is not executed, the following functions do not
operate: auto operation and key off operation.
(a) Turn the ignition switch on (IG).
(b) Make sure that the sliding roof is fully closed.
(c) Push and hold the CLOSE switch or the UP switch
until the following movement finishes: Tilt up →
approximately 1 second → tilt down → slide open →
slide closed.
(d) Check that the sliding roof stops at the fully closed
position.
(e) Finish the initialization.
(f)Check that the AUTO operation works normally.
NOTICE:
If the following conditions occur during
initialization procedure, initialization will fail.
•Ignition switch is turned off.
•Sliding roof control switch is released while
sliding roof is operating.
•Vehicle speed is 5 km/h (3 mph) or more.
•Communication is cut off.
•Another switch is turned on during
initialization.
•The vehicle experiences a strong vibration
during initialization, such as the slamming of
a door.
HINT:
•If the sliding roof cannot be fully closed or its
position has become misaligned, perform
initialization again.
•If the roof glass stops moving or starts moving in
the opposite direction while the CLOSE or UP
switch is held down, continue to hold the switch
for another 10 seconds or more to return the
sliding roof control ECU to an uninitialized
condition. Then perform the initialization
procedure again.
•If the AUTO operation function and jam
protection function do not operate after the drive
gear has been reset, replace the sliding roof
drive gear (sliding roof ECU).

DIAGNOSIS SYSTEM
1.DESCRIPTION
(a) Sliding roof system data and Diagnostic Trouble
Codes (DTCs) can be read through the vehicle's
Data Link Connector 3 (DLC3). When the system
seems to be malfunctioning, use the intelligent
tester to check for malfunctions and perform repairs.
2.CHECK DLC3
HINT:
SIL
The ECU uses ISO 15765-4 for communication. The
terminal arrangement of the DLC3 complies with SAE
J1962 and matches the ISO 15765-4 format. If the result
is not as specified, the DLC3 may have a malfunction.
Repair or replace the harness and connector.

NOTICE:
*: Before measuring the resistance, leave the vehicle
as is for at least 1 minute and do not operate the
ignition switch, any other switches or the doors.
If the result is not as specified, the DLC3 may have a
malfunction. Repair or replace the harness and
connector.
HINT:
Connect the cable of the intelligent tester to the DLC3,
turn the ignition switch on (IG) and attempt to use the
tester. If the display indicates that a communica tion error
has occurred, there is a problem either with the vehicle
or with the tester.
•If communication is normal when the tester is
connected to another vehicle, inspect the DLC3 of the
original vehicle.
•If communication is still not possible when the tester
is connected to another vehicle, the problem may be
in the tester itself. Consult the Service Department
listed in the tester's instruction manual.

ON-VEHICLE INSPECTION
1.CHECK AUTO OPERATION
(a) Turn the ignition switch on (IG).
(b) When the roof glass is fully closed, press the OPEN
switch for 0.3 seconds or more. Check that the roof
glass automatically slides until it is fully opened.
(c) When the roof glass is fully open, press the CLOSE
switch for 0.3 seconds or more. Check that the roof
glass automatically slides until it is fully closed.
(d) When the roof glass is fully closed, press the UP
switch for 0.3 seconds or more. Check that the roof
glass automatically tilts until it is fully tilted upward.
(e) When the roof glass is fully open, press the DOWN
switch for 0.3 seconds or more. Check that the roof
glass automatically tilts until it is fully tilted
downward.
(f)When the auto operation is operating, check that
pressing any personal light switch stops the roof
glass operation.
HINT:
When pressing the switch for 0.3 seconds or less,
the roof glass moves but auto operation does not
operate.
2.CHECK SLIDING ROOF OPERATION AFTER
IGNITION SWITCH IS TURNED OFF
(a) Turn the ignition switch from on (IG) to off, and
check that the sliding roof operates. Then open and
close the driver's side door once, and check that the
sliding roof does not operate.
(b) Turn the ignition switch from on (IG) to off and wait
for approximately 43 seconds. Check that the
sliding roof does not operate.
(c) Operate the auto (SLIDE OPEN/CLOSE or TILT UP/
DOWN) operation. While the roof glass is in motion,
turn the ignition switch from on (IG) to off. Check
that the auto operation continues until the roof glass
opens or closes fully.
3.CHECK JAM PROTECTION FUNCTION
CAUTION:
•Do not use a part of your body, for example, your
hand, to check the jam protection.
•Do not allow anything to become caught in the
sliding roof by accident in this procedure.
•Perform the inspection from the inside of the
vehicle.
NOTICE:
•Do not use hard objects such as a hammer, to
avoid damage to the roof.
•If the jam protection does not operate, reset the
sliding roof drive gear (motor).
SLIDING ROOF – SLIDING ROOF SYSTEM
(a) When the sliding roof auto operation is operating
and an object is caught between the vehicle body
and glass, check that the roof glass opens 218 mm
(8.58 in.) from the point of contact with the object, o r
opens fully if there is not an opening distance of 218
mm (8.58 in.).
B068295
(b) When the TIL T UP/DOWN function is operating, and
an object is caught between the vehicle body and
the roof glass, check that the sliding roof tilts up
fully.
When the sliding roof drive gear sub-assembly (sliding roof control ECU) detects malfunctions in the
motor, and the sliding roof operation is stopped, DTC B2341 is output. When the sliding roof drive gear
sub-assembly (sliding roof control ECU) detects malfunctions in the gear, and the sliding roof operation is
stopped, DTC B2344 is output.
