Hello,

 

I am having issue with my 4 electric windows on my Fabia 2008.

 

At first, it was an intermittent issue where none would work and sometimes later, they will without intervention.

Then they finally stop working, but I could run them for 10 minutes in the emergency mode by removing fuses one minute or so.

 

So I start looking into the issue, and I finally found one almost broken wire (black/blue) in the driver's door loom.

After it was fixed, I noticed that the central locking is back to work when using the key in the door.

Regarding windows functionality, it get worst: 3 windows are still working only in the emergency mode, except for the driver's window (and obviously the 4 switches command of the driver).

 

So I am now suspecting an issue with driver unit control (not sure if it is called J386?) new to the motor of the driver's door.

 

The references on the motor are

6Y2959802A
402079C HW002 SW0330
MR6
Made in france 09/08/07 08:07 T5
SK250D4DLS

 

And on the TEMIC unit control part

440778DN
402010A4
19.07.07
HW:002
SW:03XX

(on the card itself is written TSG-PQ24 290 758 04 A)

 

On the TEMIC module, there are 2 connectors:

-One has 8 pins: I checked that voltage between thick brown 1 and thick red/white 2 is around 12V.
So I was expected this would be enough for the window to run in emergency mode. Is it the case?

-One has 10 pins (for the command switches I guess).
 

Is there a simple way to test the controller? Or did I missed something?

Any hint would be appreciated!

Thanks

It is possible the control unit is faulty................however, I would also be double checking there is no more broken wires in the door loom as well.

 

 

Thank for your reply.

 

As long as the live+ground (1+2) is coming up to the module, shouldn't the window work in emergency mode for 10 minutes?

 

Not aware of the emergency mode..............not something I have seen in any literature.

I believe it should be a mandatory security feature (not to depend on a functional LinBus to get out in case of a crash for example).

 

Here is a link I found for Fabia MK1 for this emergency mode (called either "Limited function" or "Emergency operation function"):

Couldn't find it for MK2, but behavior looks similar (if you unplug control unit for driver window, other windows will work only for 10 minutes).

That's the same issue we have when the driver control unit is faulty.

That's the same issue we have when the driver control unit is faulty or the LinBus wiring is broken.
