SUBJECT
Window De-Initialization/Initialization Procedure
MODEL
E85 (Z4) produced from April 2004
SITUATION
Power windows convenience closing or automatic one-touch feature may not operate correctly.
CAUSE
The power windows will need to be de-initialized and then initialized if:
1. 1. The side windows have been adjusted (e.g. after the hardtop is fitted).
2. 2. The vehicle is new and is going through the QC1 process.
Note:
Initial window settling during vehicle's transportation from the factory can affect the clearance between the window and the convertible top seal. Therefore, it will be necessary to de-initialize and then initialize the power windows of every new E85 during the QC1 process. The power windows will need to be initialized if:
1. The battery has been disconnected.
2. The power supply to either door is disconnected.
PROCEDURE
[NEW] To de-initialize the windows:
1. Close both doors.
2. Lower both windows completely.
3. Immediately push the window switch down 4 times within 10 seconds.
4. Check that the automatic one-touch is not working.
To initialize the power windows:
1. Connect a battery charger to the vehicle.
2. Close both doors and the soft top (or hardtop installed).
3. Lower both windows completely.
4. Raise windows and hold the switches in the up position for one additional second after the windows reach the top.
5. Lower the windows 100 mm or approximately 4 inches.
6. Raise the windows and hold the switches in the up position for one additional second after the windows reach the top.
7. Close the windows using the one-touch feature function and ensure that this works correctly.
8. Check the anti-trap function by inserting a plastic rod with a diameter greater than 6 mm in the left side window between the door window and the soft-top/hardtop and then close the window with the one touch function. If the function is OK, the anti-trap function will respond.
9. Repeat step 8 above for the right side window.
10. Clear the "scaling fault" stored in the General module.
Note:
Any brief interruption in performing the above steps may require for the entire initialization procedure to be repeated.
