Title:
INITIALIZATION OF MOON ROOF
DURING PDS
Models:
'05 ± '06 ES 330
Technical Service
Information Bulletin
August 22, 2005
PD033-05
The moon roof is controlled by the sliding roof ECU, which detects and memorizes the
moon roof position by counting pulses of its motor from the fully ªTILT-UPº position as
the start position. Once the battery terminal has been disconnected and reconnected,
the sliding roof ECU does not detect and memorize the moon roof position, resulting in
no functions of the ªone-touch tilt up and down,º ªone-touch slide open and close,º and
ªjam protection.º Initialize the moon roof position after reconnecting the battery terminal
as outlined below.
NOTE:
Any time the battery terminal has been disconnected, initialize the moon roof after
reconnecting the battery terminal.
2005 ± 2006 model year ES 330 vehicles.
1. Turn the ignition switch to the
ªONº position.
2. Push and hold the moon roof switch
to the ªTILT-UPº side until the moon
roof tilts all the way up and then tilts
down slightly (approximately 10 mm
[0.39 in.] at rear end).
3. Check for proper operation of the
ªone-touch slide open and closeº and
ªone-touch tilt up and downº functions
by pushing the switch briefly to the
ªSLIDE OPENº and ªTILT-UPº positions.
NOTE:
Jam protection function becomes
effective through the above
initialization procedure.

INITIAL CALIBRATION OF COMPASS DURING PDS ± PD034-05 August 22, 2005
Page 3 of 3
3. Check that the direction appears
several seconds after adjustment.
4. Start the engine and push the switch
for about 6 seconds until ªCº appears
on the display.
5. Drive the vehicle slowly at 5 mph
(8 km/h), or less, in a circle until the
direction is displayed. If there is not
enough space to drive in a circle,
drive around the block until the
direction is displayed.
After driving in 1 to 3 circles,
calibration is complete with the
direction shown on the display.
NOTE:
Do NOT perform calibration of the compass in a place where the Earth's magnetic
field is subject to interference by artificial magnetic fields (underground parking,
under a steel tower, between buildings, roof parking, near a railroad crossing, near
a large vehicle, etc.)
During calibration, do NOT operate electric systems (moon roof, power windows,
etc.) as they may interfere with the calibration. Compass
