Looking for F01 wiring diagrams

[Nachev]

I have bought a 7-series f01 2011, the start/stop button’s wires have been cut off. I would have just bought a new button, but they have cut the cables that come out of the car, not the ones from the button. Now I need to connect them back to be able to put in the new start/stop button. Anyone know were I can find the wiring diagrams?

"cables that come out of the car" is a bit vague...can you post a picture?

ISTA will have wiring diagrams, but if you provide a bit more detail of the exact harness location, or group of wires, I can look them up for you on TIS.

Please note, that there is a limit on how much information I can post from TIS, since the wiring diagrams on TIS are large, and multilayered (hyperlinked to other info), but I can try and give it a shot.

I don't know the exact name of the module, but the wires are the ones that connect to the 10 pin connector. This 10 pin connector connects to the start/stop button. Here is a picture.

Those don't look like the wires to your "start/stop" button, and I don't think the pre-LCI F01 had the "automatic" version...and per RealOEM, the P/N for your "start/stop" button is 61319153832 (item 1 in the image below)

...so based on realoem, and TIS, the wires you have in your picture do not belong to the "start/stop" button based on the following:

1. The start button wiring should ALL be 0.35mm wires, and you have a red and brown wire that are larger gauge wires
2. The start button does not use a CAN bus wire pair, and your picture has the twisted CAN bus wire pair in it
3. None of your wire colors in your picture match those required for the Start/Stop button wiring loom (pre-LCI, nor LCI)

Regardless, I have provided both the pre-LCI (w/o automatic) button and LCI START/STOP (w/ automatic) button wiring diagrams below which is wired directly to your CAS module.

A quick way to verify all of this, is to locate your CAS module, and verify on the CAS Connector A16*2B, that the wires from pins 6, 8, 5, 21, 7, 18, 9 and 22 are matched to the wires in your picture....I suspect they don't.

I've added a picture of the CAS location in your F01 and it's corresponding connector assignment.

...what could help is if you could zoom your picture out, and show where the wiring harness comes out from the dashboard....

Are there other unaccounted for items missing from the dashboard?

I do see that your HVAC controller (A95) is missing, the center console emergency flasher button is missing, and the door lock button is missing from in your picture.....so you have connectors accounted for these items?

FYI, a 0.75mm solid red wire (no stripe), a 0.75mm solid brown wire (no stripe) and a 0.5mm white wire (no stripe) are usually assigned to a LIN bus. But your 0.75mm red wire looks like it has a stripe on it, which means its a power wire from the fuse box.

A twisted pair of 0.35mm wire pair (green + orange/green) are reserved for the K-CAN bus.

So we need to find a missing electrical item besides your start/stop button....


Note: the 10-conductor connector below is used throughout your vehicle on multiple connections.

Here are some photos from further away:

Nachev , that is absolutely a better picture....

I've labeled your photo with 1, 2 & 3 in the 1st picture....

1. Arrow 1: Wiring harness (portion) that goes to your start/stop button, and if peel back a bit of the wrap, there should be more wires
   
2. Arrow 2: Wiring Harness that goes to your HVAC control panel
   
3. Arrow 3: Wires harness (portion ) that go to the center vents (arrow is pointing to the harness, not the single wire)

When I too my dash apart to clean it and it's provided in the 2nd picture.

Let me know if you need more help. Between my car and access to TIS, I should be able to help you enough to get your connectors rebuilt and able to plug into their corresponding sockets.

Cheers
