How To: Initialise windows after disconnecting the battery

Postby AlexB » Tue Apr 28, 2009 11:42 pm

I just discovered that the traditional advice regarding window initialisation is significantly different from the manual. According to the manual the following steps must be performed after re-connecting the battery:

1. Lift the window. It will move in small steps.
2. Once it is fully closed, lift and hold the corresponding switch on the driver's door for longer than 2 seconds.
3. Lower the window fully.
4. Once it is fully open, press and hold the corresponding switch on the driver's door for longer than 2 seconds.

Done! This is for the pulsed window regulators, whose switches have two positions. Check it by gently pressing the driver's switch. You will hear click-click -- two distinct clicks corresponding to two positions. The first is the pulse and the second is the continuous movement mode. So, each switch has two positions down and two positions up in addition to the neutral state.

Note: this can be done for a single window or one window at a time. This is according to the manual -- somebody check it!

Note: I would imagine that if this calibration is incorrect, then the window may go too far, thus triggering the child safety mechanism that causes it to go down immediately. Otherwise, if the window misses the "low" position, then it potentially can damage the mechanism of the regulator -- someone comment on this!

Hi Alex

Just tested this and your correct
Had to do these steps on all 4 windows but it works perfect now

Didn't know anything about the 10 secs one

However I do know I had run the same step on each window

This is exactly my point. There is nothing in the manual about 10 seconds or pressing/lifting all switches simultaneously. Furthermore, both the upper and the lower positions must be calibrated. There is nothing about resetting the windows apart from disconnecting the battery.

Re the window problems, when it says goes up in steps, does this mean window switched pressed then window keeps stopping or the only way to close is to hold the switch....sorry for stupid question rough night. :scuse2:

Yes, the switch is pressed/pulled up continuously -- the window moves down/up by a few cm (4-5cm) and then stops on its own. In order to move it further, one needs to release and then operate the switch again. Once the child safety feature is activated by calibrating the top and bottom positions of the window, it acquires its usual ability to move continuously. Then it moves continuously either (a) while the switch is held pressed/pulled up (first click position) or (b) if it is pressed/pulled up hard (second click position) and subsequently released. (a) is the pulse function and (b) is the one-touch function.

Windows go down at one touch but have to keep button pressed up to close, does not stop just have to hold button up.

What happens when you use the other switch, does the window work correctly then?

If so, sounds like a faulty switch or switch supply to me.

The switches contain the contact groups allegedly made by Philips and known to fail in some telephone applications. Look at the truth tables in the manual. The actions of the controller are encoded as combinations of contacts. If one fails, the whole thing may start executing the wrong commands.

I guess you felt the draft coming from the switch assembly. Can it be related to the condition of the mechanical contacts? I wouldn't be surprised if many cases when the controller is replaced can be actually explained by a dirty contact...

BTW, can you hear the second click when pulling the switch up?
