Dual Pane Sunroof Or Sunshade Override Position Calibration: Sunshade

The sunshade motor stalls when the shade reaches the fully closed position and the electronic motor module learns that position (hard stop), then counts the number of motor rotations to know where the mid-opened and fully opened positions of the shade are located. The following procedure causes a previously calibrated and properly operating electronic motor module to relearn the fully closed motor stall position.

1. Be certain electrical system voltage is at or above 12.5 volts.
2. Be certain the key is in the ignition switch and the switch is in the ON position.
3. Be certain the sliding glass panel is in the fully closed position.
4. Depress and hold the CLOSE push button of the sunshade switch until the shade is in the fully closed position or until the motor will not drive the shade any further towards the fully closed position.
5. Open the driver side front door.
6. Turn the ignition switch to the OFF position.
7. Within 2 seconds, turn the ignition switch back to the ON position.
8. Within 2 seconds, depress and hold the CLOSE push button of the sunshade switch for about ten seconds. At the end of ten seconds, the motor will try to drive the shade to the fully closed position. Once motor stall is detected, the electronic module will write that stall position to memory as the new shade position.
9. Verify sunshade motor operation by cycling the shade to mid-opened, fully opened, then fully closed again.
