Since 2003, a series of articles were freely published on the Peugeot Cabriolet Owners Club website providing technical guidance and other useful information.
These articles are then illegally reproduced and sold on eBay as a PDF guide. So, to help owners of 306 Cabriolets all over the world live with their chosen ride, this PDF is now published for free here - exactly how the original authors/contributors intended!
Thanks to all those who produced the original material for these articles (see www.pcoclub.org/articles for full details and additcional articles).

The 306 Cabriolet is fitted with a safety mechanism which blocks the electric hood controller so that the hood cannot be operated when the engine is running. In fact, it is a security precaution that works well but which presents some disadvantages, notably by obliging us to stop and turn off the engine leading to wasted time during urgent hood-raising (rain). It is also a problem for weak batteries, and a certain annoyance in having to start up again afterwards.
This article proposes a method of rectifying this little inconvenience by modifying the safety mechanism so that it operates in a more rational way, equivalent to that of a Mégane cabrio whose only security is that the hand brake be applied to the point where the dashboard warning light is illuminated. This allows the possibility of starting to move at low speed (you have to be reasonable) while finishing operating the hood.
|Tools and components required|
You will need:
The operation consists of passing an electric cable from the electric hood's control unit which is situated just below the off-side rear light, up to the hand brake lever. Some rightly say that this is not easy - especially the part under the carpet for the rear passengers - but then again, nothing is impossible!
Initially, you need to:
Now comes the most complicated part of this modification; fitting of the wire from the control unit up to the handbrake and passing under the carpet of the rear passenger compartment and under the boot carpet.
Once the electric cable has been installed, we can connect it to the movement sensor of the handbrake, thanks to the "fast-on" connector that we will connect to the male connector that is available unused on this movement sensor.
The problem is that when this second connector is attached, it is difficult to reattach the movement sensor, so one can (as in my case) cut the original wire and attach the three wires together. That is to say the wire connected to the movement sensor, the original wire and the new one, all connected together with the aid of a connector block (for example).
Once the wires are connected, the effect is that the new wire will be connected to earth when the handbrake is applied, so one can replace the central cowling over the handbrake, replace the two screws holding the backrest and replace the squab of the rear seats.
We now arrive at the modification at the control unit (roof ECU) end, which may appear complicated, but which is in fact very simple.
|Location of wires|
All that is left to do is to replace the connector on the control unit, put back the carpet, replace the rear part of the light unit and reconnect the battery if you had disconnected it.
Now you can test whether the modification works:
It only remains to test a hood movement in real conditions to appreciate the benefits of this modification which is not difficult to achieve but so practical in everyday use.
Caution: this modification requires a few important recommendations:
Keep to a low speed when moving the hood (10mph / 15km/h max), above which the sail effect would be too great and would result in damage to the hood, its mechanism and the hood cover.
Remember that lowering the hood is easier than raising it and therefore less dangerous on the move (because of the handles that need to be closed).
