Window Indexing
#1
![Default](/forum/images/icons/icon1.gif)
So my new to me svr convertible has a window that appears to rub the convertible top and this makes is slightly difficult to close. I just noticed the passenger side indexes (window slightly opens when opening or closing the door) and the drivers side does not. Comming from GM, there are dozens of posts on indexing the windows on Camaros' Corvettes etc, but I cant find anything on the f-type. A.Is the window supposed to index? (maybe jaguar calls it something different and that is why I can't find it? ) B. If so, is there a way to reset it?

Thanks all, found in the manual and yup it says "Lift the switch to the close position and hold for 2 seconds. Repeat this process a total of five times." I did that and no door indexing. I then went to passenger side and it indexes perfectly. So, something must be wrong with drivers side circuit responsible for indexing the window. .

Edit: More Info for you:
The passenger and driver door windows operate when the ignition is in accessory mode or the ignition is on. The windows will operate for 5 minutes after the ignition is switched off, as long as none of the doors are opened.
To open or close the door window when a door opens or closes, the CJB uses inputs from the door window drop switches in the interior and exterior door handles and the ajar switch in the door latch. The CJB then signals the related door module on the Medium Speed (MS) Controller Area Network (CAN)body systems bus to operate the door window as required.
The signals to open or close the door window when the folding top opens or closes are provided by the master FTCM (Folding Top Control Module) on the HS (High Speed) CAN chassis systems bus. The signals are transmitted to both door modules on the MS CAN body systems bus via the GWM (Gateway Module).
DESCRIPTION AND OPERATION
When a window open or close selection is made on a door switch pack, the related door module supplies power to the window motor to drive it in the appropriate direction. In the inch mode, the motor stops when the switch is released or the window reaches the end of its travel. In the one-shot mode, the motor stops if the switch is operated again (either up or down) or the window reaches the end of its travel.
One-shot up operation causes a door window to fully close unless an object is detected (anti-trap) or the glass is within 12 mm (0.47 in) of the top of the travel when the door is open. If the
anti-trap algorithm detects an object, the glass will drop fully open or to 200 mm (7.87 in) below the obstruction.
When the passenger door switch pack is used, it produces an open or close request by completing a hardwired circuit with the PDM (Passenger Door Module).
When the driver door switch pack is used, it outputs a request message to the DDM (Driver Door Module) on the LIN (Local Interconnect Network) bus. If the message is for the passenger door window, the DDM relays the message to the PDM on the MS CAN body systems bus. If the passenger door window has opposing up and down requests from the passenger door switch pack and the driver door switch pack, operation of the door window will cease until one of the switches is released.
ANTI-TRAP PROTECTION
The anti-trap feature is incorporated for the door window in both the inching and one-shot modes. If the anti-trap function is activated while a window is closing, the window will reverse by approximately 200mm (7.87 in).
Each window motor has two Hall effect sensors to enable the related door module to monitor the motor speed. If the motor speed decreases below a set threshold, indicating an obstruction, the power feed to the motor is reversed so the window goes back down.
If it is still necessary to raise the window, the anti-trap protection can be overridden by attempting to close the window at intervals of less than 10 seconds. On the third attempt the window will move up with
anti-trap protection disabled to overcome the obstruction.

Thanks gents, this clears up one thing for me - resetting the one touch up/down.
Every time in the past that I have needed to reset this it ONLY worked while the car was in motion.
BUT I thought you only had to do it once not five times so I have never tried five times, maybe next time I will.
Thing is, if you are lazy and can't be bothered doing it five times then you can try my method - do it while driving - as that way only takes one go!
