SUNROOF INOPERATIVE

APPLIED VEHICLE:
All 2003-04 G35 Coupe (CV35)
All 2003-04 FX35 and FX45 (S50)

IF YOU CONFIRM:

The sunroof doesn't close or open automatically using the slide switch and/or tilt switch.

ACTION:

Reset the Sunroof memory.
^ Generally resetting the Sunroof memory will resolve the incident.
^ Usually there is no need to replace the Sunroof Motor.

You will also need to reset the sunroof memory if any one of the following conditions has occurred:
^ Battery removed or battery cable(s) disconnected while sunroof is operating or within 5 seconds after the sunroof movement has stopped.
^ Sunroof motor is replaced.
^ Sunroof emergency/manual operation procedure is used.
^ Interruption during the Sunroof memory resetting process.

See the SERVICE PROCEDURE for the Sunroof memory reset procedure.

IMPORTANT NOTE:
^ If only the Sunroof memory needs resetting replacing the sunroof motor will do no good (won't fix the incident).
^ In cases of a Sunroof "open/close" incident do not replace the sunroof motor first. Perform the SERVICE PROCEDURE below.

SERVICE PROCEDURE

Reset the Sunroof memory as follows:





NOTE:
You'll use the "tilt-open" function of the Sunroof TILT Switch (see Figure 1) for both steps below.

1. Press and hold the Sunroof TILT switch in the "tilt-open" position (see Figure 1) until the Sunroof does all of the following (in the order shown):
a. Moves in small increments (a few inches at a time) to the fully closed position.
^ This movement will occur if the sunroof is in the open position.
^ If the sunroof is in the closed position this movement will not occur.
b. Tilts UP fully
c. Finally tilts DOWN into the closed position.

2. Within 5 seconds after the Sunroof tilts closed: Release the TILT switch. Then Press and hold the TILT switch again in the "tilt-open" position until the Sunroof does all of the following (in the order shown):
a. Slides completely open
b. Slides completely closed
c. Tilts fully open
d. Finally tilts fully closed.

3. Release the tilt switch. The Sunroof memory is now reset.

4. Check the Sunroof slide and tilt switches for proper operation.
