Wireless Charger install on 2017

[Nazsky786]

Hi,

Ive installed a wireless charger centre console from a 2023, ive used my old loom or else the car wont start and taken the 3 wires from the 2023 loom for the charger but the place where the wires go on the original loom are already populated. 

Where do the 3 wires go as this car isn't supported to have the volvo charger. And on orbit what options do I need to change?

I have red, black and white. I'm guessing the red and black are power and ground but white is control but where do I install that?

Thanks.

Also what option do I choose on orbit? There is with on off button but is nfc used?

The red power goes to the fuse box, It has its own 5amp fuse. (you can use a fuse tab) 
The Black is the ground. you can get it from the passenger side under the center console behind the carpet. 
The White one is the LIN communication goes to the CEM.  FL 41.

Any chance you know what options are to be selected on Orbit?

I have Orbit set to;

366 Wireless Phone Charger - 04 Inductive charging for smartphone + OnOff Btn
450 Wireless Phone Charging And NFC - 04 With NFC & WPC

I don't have the option on Sensus to turn on the wireless charging pad so its not working.

Thanks

It depends on the unit you are installing. There are different variants of the wireless charging. 
In addition, the FL 41 pin of the CEM where the wireless unit LIN is connected is empty on some of the CEMs. If your CEM does not have that pin, enabling it does not do anything.

Ok, So the CEM does have all the pins at the FL connector populated, so its connected to something. 

I think its has to do with the configuration as its not turning on the wireless charging pad unless the button on Sensus is there. Which right now its not and I have a invalid config dtc. 

I'm going to try keeping the 450 turned off and and leave 366 as is. 

After a reset see if it does show the button.

Hi!
I am doing the same operation, retrofitting wireless charger on my MY2020 XC60.
Can You please tell med which connector on the CEM is the "FL".
Best regards

[Nazsky786]

Here is the CEM Module FL is the Brown connector,

FYI, Fords was Green from Engine Bay, Brown for Floor Blue for Dash. Seems Colvo carried on this trend.

Waiting on Support for help on activation as its not working for me even with High CEM and the opinion choosen on Orbit. WIRELESS charging + OnOff.

Many thanks, will try this, but i assume it will not work as this was not an option for my car. 
The LIN do not just turn the charger on and off, it is controlled by a button on the screen and sends messages to the dash if there is foreign objects on the pad ,so as this is not in the ICU i assume it wont work, but i will try.
I am thinking of putting a single chip LIN controller to emulate the on /off and connect this to the LIN wire, maybe someone has tried that? The LIN protocol seems easy and cheap.

It's not that simple (on / off) and hacking the LIN is much harder than hacking the CAN BUS. 
LIN bus works in master  / slave and each node has its own unique identifier and each node responds to specific messages (message IDs) from those unique nodes and a LIN bus network cannot have more than 1 master node. 
First, there is a handshake initiated via Master (in your case CEM) which the slave (wireless charger) responses. 
Then CEM (master) send operational command and the wireless charger (slave) responses with status. 

VOLVO makes CAN, LIN and FLEXRAY buses much harder to hack by sending same operational commands every couple of milliseconds and not by just charging couple of bytes in the messages only once. 

This means, 
CEM sends handshake message if the wireless charging option is enabled. 
Then by default CEM sends turn off charging message to slave "your wireless charger" every couple of milliseconds. 
User presses on turn on wireless from the screen. 
IHU sends turn on wireless request to CEM via Flexray every couple of milliseconds and waits for response. 
CEM sends turn on charging message to slave "your wireless charger" every couple of milliseconds. and waits for response. 
If the wireless charger does not receive "turn on" command every x millisecond, it turns itself off. 

In order to hack the LIN bus you will need to build a man in the middle board that has one slave "acts as wireless charger" and a master "acts as CEM". 
In between your code should catch, manipulate and respond on both sides.   

So, instead of getting into this trouble, just order a wireless charger from amazon or aliexpress for $40 that also has two additional USB ports powered from the cigarette lighter.

Hi!
Many thanks for this very good explanation, very impressive and much appreciated.
Saved me a lot of speculations.
Is it in Your opinion worth the trouble to try to connect to FL 41 in an MY2020 as they do not have this as an option?
I also tried the new light above the rear seat by changing the connector and that did not work either, so even a simple thing as this do not work because of what you just decribed.
