Dismantling Maxi Cosi Car Seat Base: Steps to Access Broken Wire Sensor

Question

How to take apart maxi cosi car seat base? Need to get inside because one of the sensors has a broken wire and communicates all the time that it is incorrectly plugged into the isofix base, even though everything is fine. I have already made two approaches to take the base apart but without...

A snippet of information here: When you get inside, photograph these contacts/sensors please.

Hello,
I'm adding here because overall the topic is similar. If anyone had problems with the diode regarding isofix attachment. Most likely the cable has broken. Most often it is at the sliding mounts from isofix, as in the pictures below. After a quick soldering, everything should work.

I also need to take apart the base to solder the rubbed isofix sensor wires. However, the main screws have some strange heads, neither torx nor allen...
I managed to remove all the plastics, but I'm stuck at the screw stage, which is the start. Anyone has such a screwdriver, wrench and can take a photo?

Show it in the picture.

Rafer · Answer

The screws are in the tunnels, it is difficult to catch them in such a way that they are visible.

raudek · Answer

Make a headprint, then you'll see what you're dealing with.

mastkon · Answer

I have the same problem. Has anyone managed to take apart the base, if so please give me a hint.

czytad · Answer

I found two additional screws that attach the lower part of the base housing, hidden behind the plastic part covering the movable hooks for attaching the base to the car (rails in yellow). Attached is a photo of the screw head and where the additional two screws are located. I found the place where the wire is broken off. Unfortunately, something is still blocking the removal of the lower cover.

Hello I have figured out the whole topic regarding this base. If you need any help, I'm here to help. The base can be taken apart, except for the yellow slide-out component, it is riveted.

czytad · Answer

If you could give more details on how to take the base apart, I would be very grateful. Pictures welcome

mastkon · Answer

Ok. I'll try to post something, and which component repair are you interested in?

czytad · Answer

I have a broken wire coming to the yellow rail and do not know how to get to it. Attached is a picture of the severed wire.

mastkon · Answer

At the end of the guide, where you slide out the guide (yellow) there is a steel pin marked with a dot.
You need to slide it out. From the inside, lever it up with a screwdriver and when it comes out a little, then unscrew it with pliers.
This pin is secured from sliding out by a pin, no worries, you will not break it, it is pressed in. And it is she who will put resistance when pulling out.
Removing the pin, you will pull out the guide together with the cable.
The black guide is detachable. It should be lifted from both sides and you will open it.
It is best to photograph each operation, so as not to get lost later when assembling.
To disconnect the cable is to unscrew the plate on which the batteries are located, solder and connect.
Beware of the strange mechanism that tightens the cable in the guide and, of course, nothing by force, it is about the cable, so as not to break it in another place.
I'll try to post pictures as soon as possible.
Good luck

You don't have to take the whole base apart, as I did. All you need to do is unbolt the guide and unscrew the plate in place of the battery

I approached the topic (repair) for the first time about a month ago. On the forum I asked for help. Thank you for your interest and attempt to help. At the moment the seat is on leave and I do not have access to it. I would appreciate any photos. Next week I will make a second approach to the subject.

mastkon · Answer

I also made two approaches. The first time I was afraid that I would completely destroy it therefore I gave it a rest. On the second approach I took it apart, except for the yellow slide-out part.

Could someone please write what I need to do one by one to disassemble the 2wayfix base to be able to solder the broken cable at the iso plug-in guides?

mastkon · Answer

Hi. All you need to do is remove the pin, as in the description above, and that's it. The guide slides out together with the connecting wire.

kaisyrk79 · Answer

I'll give it a try, just how do I remove those gray plastics that you grab to move the guides/unplug/attach to the base? Without that, I can't remove the plastic that covers the guide....

Maniek_! · Answer

You grab and pull it towards you (up-down motions). They sit on the two pins quite firmly.

dar_o · Answer

As if anyone needs, I've provided a photo of what the isofix base looks like after unscrewing the base. After unscrewing all the screws from underneath, I was able to remove the top and free the seat - which, not knowing why, locked

gumi · Answer

Removal of these pins is somehow impossible, I do not know how it can be pulled out.

Maniek_! · Answer

Pray with WD40 and use force + a large flathead screwdriver on the inside. It will not pop out by itself .

Mario 1410 · Answer

I also have a broken cable signaling the attachment of the isofix system in the maxi cosi 2 way base and I can not pull out the pin that attaches the guide, Only that in this model the pin is all the way through and goes through 2 guides, I do not see any pin, the pin turns but something is holding it and I do not know what. Maybe someone can help?

Mario 1410 · Answer

The topic mastered. After many attempts, it turned out that it is necessary to use considerable force and pull out the pin with a length of 6 cm. In this model of the base there is no pin, Further disassembling the black rail and getting to the broken cable very simple. Good luck.

AgnieszkaSekua · Answer

I apologize in advance for the stupid question, but do you mount batteries to the FamilyFix2 base? In the instructions not a word about it, under the base there is like a place for them but there are no contacts or markings there.... and the LEDs do not light up what could be the problem?

Mario 1410 · Answer

From what I remember, the place for the batteries (2 sticks) is on the bottom of the base.
