Switch Replacement - Sunroof Position Encoding System

REMOVAL PROCEDURE

IMPORTANT:
^ Remove the headliner.
^ The sunroof positioning encoding (SPE) switch is aligned to the drive cables. The SPE switch comes from the factory set to the sunroof glass panel CLOSED position. A position lock pin has been installed by the factory on the top of the SPE switch. This pin must remain until after the installation of the sunroof actuator and of the SPE switch. This lock pin locks the drive gears in place and must be removed before the complete sunroof module is installed to the vehicle
^ If the SPE switch is removed for inspection, the sunroof must be in the CLOSED position A position lock pin must be inserted. If a position lock pin is not available, place 2 wires, such as the ends of a paper clip, in the holes.

1. Move the sunroof to the closed position.
2. Remove the sunroof glass panel.
3. Remove the sunroof module.




4. If you reuse the SPE switch, insert the position lock pin (1) in order to lock the SPE switch in the closed position.
5. Remove the sunroof motor.
6. Disconnect the electrical connector from the SPE switch (3).
7. Remove the screw (2) which secures the SPE switch to the sunroof module.
8. Hold down on both of the drive cables. Lift up on the SPE switch in order to remove the switch from the sunroof module.

INSTALLATION PROCEDURE

IMPORTANT: The cable mechanisms and/or the cam mechanisms, on both sides of the glass, contain a set of timing holes. These holes are aligned in the CLOSED position of the sunroof glass panel. These holes are located on the side opposite the rear screw hole, which is used in order to mount the sunroof glass panel. When installing a new sunroof position encoding (SPE) switch, set the sunroof glass panel to the CLOSED position.




1. Use a flat-bladed tool if you adjust the cable mechanism and/or the cam mechanism in order to align the cable and/or the cam timing holes.
When the timing holes are aligned, insert a pin with diameter 0.0317 mm (1/8 in) or a drill bit (1) into each set of the timing holes. Use tape in order to hold each pin in place.

IMPORTANT: The SPE switch comes from the factory with a position lock pin that is installed on top of the switch. This locks the timing gears in place. Do not remove the position lock pin until after the SPE switch and the actuator are installed.




2. Keeping the position lock pin on the new SPE switch, align the switch over the drive cables.
3. Apply pressure to the SPE switch until the switch is completely seated.
If the switch does not slide into position, the ridges on the drive cable housings will not go into the grooves on the back of the SPE switch. Lift each cable into the switch, and press down on the assembly until the assembly is completely seated.

NOTE: Refer to Fastener Notice in Service Precautions.




4. Install the screw which secures the SPE switch to the sunroof module.

Tighten
Tighten the screw to 3.4 N.m (30 lb in).

5. Connect the electrical connector to the SPE switch.
6. Install the sun roof motor.
7. Remove the position lock pin (1).
8. Remove the 2 alignment pins from the cable mechanisms and/or from the cam mechanisms.
9. Install the sunroof module, but do not install the headliner until after the sunroof operation has been verified.
10. Verify the operation of the sunroof module.
11. Install the sunroof glass panel.
12. Install the headliner.
