T6 Caravelle (LHD) - Switching Double Passenger (airbag, heating) to Single Passenger (airbag, heating) sensor [Resolved]

Dear forum members,

Is anyone able to assist with the following;

We have a double passenger bench with seat airbag and heating, and have purchased a single passenger (captain chair) with airbag + heating.

My assumption is, I can connect the current airbag sensor (assuming just 1) to the new seat connector, ensuring no airbag error codes. This applies also to the heating connector also (assuming its just 1 connector).

However, is there a seat belt sensor in the double? and is it one sensor or two? If 1, can I just connect this to the new seat also.

I.e do they align up without any issue as below, or its not that simple :)

Double Seat connectors

1x airbag (?)
1x Heating (?)
1x seat belt (?)

Single Passenger

1x airbag
1x heating
1 seat belt

Attached some pics for reference of current setup (I understand some are not connectors related to the seat).


Many thanks,
Alan

This thread may help answer some of not all of the questions and get you a bit further:

Ace thanks. It seems many are replacing the double bench with non-airbag / heating seats. I guess I will see when the single seat arrives :D

I am living in Switzerland and the regs are quite strict on parts being approved etc.
 
For anyone who this helps.

The airbag and seat heating connectors where exactly the same on the single as on the double seat. The seat was plug and play, no dashboard errors.

Swapping a double with heating and airbag for a single with seating and airbag is 100% compatible.

There is a seat occupancy sensor in the single but as the double doesn't seem to have this, the van didn't have the option to connect one to the seat. Replacing no seat with no seat sensor is not a problem.

Thanks for this info. Appreciate you taking time to feedback on your outcome . I fitted a driver swivel yesterday (RIB) into our t6.1 shuttle. Plan was to also install the Kiravans double swivel on the passenger side as have double bench seat and the new style Kiravans double swivel has the ‘holey’ bolt in the centre to pass any seat related wiring through. Trouble is, I’m not entirely happy with the way Kiravans suggest patching any needed seat wires to extend them through the central holey bolt.

In the Shuttle we have, there’s only one seat related connector which is the side air bag (3 wire type: green, white and brown). The other ‘connectors’ under the double bench seat currently are the front and rear loom connectors and the 11 way blade fuse strip/block (with two 20A fuses in). I’m still deliberating best way through situation but really don’t want to splice the airbag wiring to install the supplied ‘extension’ wires to allow them to pass through the new design hollow central ‘holey’ bolt in the double swivel. While I have to credit Kiravans for what looks like a quality product and progressive design approach with the bottom plate and carpet to cover the swivel once installed, and also redesigning the central bolt to allow wires to pass through, I’m not entirely happy with the way Kiravans are suggesting splicing and extending a patch cable into what is an SRS system.

My suggestion would be to create a bigger diameter ‘holey bolt’ and if this was generally more substantial to accommodate a larger central hollow diameter, I reckon you could have it such that the seat connectors would pass through without having to splice. I appreciate that’s easy me saying this based on one set of circumstances I’m faced with. I’m guessing, if they could have designed in a larger diameter central hollow bolt they would have.

Anyway, the reason I’m responding here, to thank you @mispeltyouth is that one of the ‘options’ to get through our situation is to do-away with the double Shuttle passenger seat upfront and install a single seat and put it on a single swivel (if we don’t source a single with factory swivel). The swivel I installed yesterday on the drivers seat has a large central hole which cabling has no issue passing through and in operation of the swivel, there is no apparent risk of damaging any cables the way they are protected with fabric wrap/tape and the position they are located means they run through the centre of the hole in the swivel.

My only question if we went this route with replacing the double passenger with a single seat, was whether a single seat airbag would somehow have a different connector or airbag ‘setting’ to the current double one we have. The fact you’ve responded saying ‘100% compatible’ is reassuring. As we’ve no heating or occupancy sensor in the double seat currently, if we got a single heated seat with occupancy sensor this would leave us in a similar position to what you mentioned. The van system would only be ‘looking’ for the airbag and won’t be ‘looking’ for heating or seat occupancy. If the single seat airbag connector is the same as double seat then swapping to a single seat is probably the option we can now look at.

Do still need to make sure the airbag system yellow connector in any single seat we source is the same as the one we have in the double seat currently. The connector in your photos is different to ours.

Hi @JENXFIVE, glad to hear this was helpful and thank you for the feedback.

In my opinion a single seat is a big improvement over the double. We paid 1000 euro for a single with airbag, heating and same Pandu upholstery. It was not the cheapest but it is not often the exact spec required comes around on the second hand market (even if we did buy from germany).

My wife and I find it much more comfortable and as we are covering a LWB caravelle (UK shuttle) to a camper it also makes the area feel more roomy, and less cut off from the rear where our 3 little ones sit.

If there is anything I can help or take a picture of let me know and good luck with the next steps.

Hi @mispeltyouth - thanks for taking the time.

I have 2 questions...

If dealing with basic seats i.e. no heating or air bags - does that mean there are no wires at all to connect up?

My double bench is on a swivel but want to go to a single passenger, looks like yours with wires attached to seatbelt buckle receiver...does this not have to plug into 'the van'?
If the seat sensor isn't connected does it not affect the operation of the airbag in the dash if you had a bump?

Thanks
 
Hi Yoshimi,

Glad the post was somewhat useful.

Unfortunately, I only have experience with this setup. If you don't have heating or airbags I am not sure if there would be any connection.

My double did not have a seat occupancy sensor and I would guess this is standard for all doubles but I have no idea.

I would also expect any car dash airbag system to fire off independently as a standalone system regardless if the seat is occupied or not, as an impact in the local area is the trigger.

My expectation would be if you have a double without airbag and heating, you can simply swap for a single without airbag and heating.

If you bought a single with an air bag, I am not sure the connector would be present in the vehicle to hook up, therefore the car computer would not expect to detect an airbag.
