You're Welcome guys!

I've just changed my webpage a little bit: This Howto may not work properly, since there may be translation errors or uncomplete translations. Maybe Renault changed something on the harware, some guys inted to lokk in their doors and check, don't know when we have news...

If you have hot information on this topic just give a note here or at

Nope, the mirrors motors never actually needed fixing. They were two of the few things on the car that actually stood the test of time

I've never been convinced that the cars are multiplexed - certainly not entirely. The road lights seem to be pretty conventionally wired, and even Renault's own towbar wiring kit doesn't use bypass relays. There are still plenty of wiring looms running here, there and everywhere.

Looking at both of the Renault RTA diagrams linked on the site, it would seem that they've gone for a multiplex solution to achieve the seat and mirror memory function. They may have since decided to use this system with these features disabled on other models, but I wouldn't take it as read and think we need a definitive way of knowing before anyone goes ahead and tries this mod.

To further confuse matters, the multiplex diagram states at the bottom that it's for models with electrochrome (door) mirrors. I know that was a feature on the original Initiale, but mine doesn't appear to have them

Confusion all around. Why is nothing in life straightforward? I agree, until we get accurate info it is not worth messing with the wiring.

I'm not sure I understand this, as the mirrors on my current Initiale appear to work in exactly the same way as they did on my Privelege, except for the fact that they have the memory function (which doesn't appear to make any difference to the switch.)

I also remembered that the Pug actually tied the mirrors into the central locking rather than the ignition. Now that'd be an even neater trick. Can anyone work out a circuit to do that?
If your mirror has a memory, then it must have position feedback on the mirror location, and this is apparent in the Multiplexed wiring diagram. This uses the logic contained in the 29 pin block associated with the window motor. My understanding is that this is the local hub for the CAN bus, and thence drives the local actuators as if on a hard-wired car.
For the sake of the motor folding, it simplified things, as all that comes from the switch is a signal requesting "Fold" (rather than drive commands for "Fold" and "Deploy") and any time you duplicate that request, the mirrors will fold.
However, the request must be in place all the time you want the mirrors to remain folded, and the central locking (probably) only sends a "momentary" signal, which you would have to create some form of latching logic for.
Cannot immediately think of any signal that has this sort of logic, except perhaps the window control (which remains active until you shut the drivers door after removing the ignition).
Note that further down the French thread, there is the switch mod to isolate this relay, so the mirrors remain only under manual control for the multiplexed version. (The non-multiplexed bypass mod is in its original post)
But what is the problem with having the mirrors open only when the ignition is active? What alternative operation are you trying to achieve?
