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.

Technical Service
Information Bulletin
August 25, 2005
PD035-05
The ES 330 is equipped with front and rear torque box holes to tie down the vehicle
during transportation. Rubber body plugs need to be installed during Pre-Delivery

Four (4) rubber body plugs are included in the glove compartment at the assembly plant.
Install them into the two (2) front and two (2) rear torque box holes located under the
vehicle on both sides.
NOTE:
If the rubber body plugs are NOT securely installed, road (tire) noise will transfer to
the vehicle interior through the torque box holes and rust could occur inside the
torque boxes by water entry.

validated by TIS (Technical Information System) in order to return a Passcode.
2. Using TIS, select Immobilizer Reset, and complete the request form to retrieve a
ªPasscode Number.º
A ªPasscode Numberº is a unique number required by the Diagnostic Tester to
reset the ECU allowing it to accept a new Master Key.

1. Transponder Key Type
Before any Immobilizer functions are performed, verify the type of transponder key
that you are attempting to use for the service operation. Some functions may only be
performed with a registered Master Key.
2. Transponder Code Registration
This function allows the registration of additional transponder keys (Master or Sub)
using a registered Master Key.
