Hello friend,

Unfortunately, some wires to sliding door are broken. Some green wires are disconnected from connector, and I do not know where green wires should be connected. It is 21 pin (it is 22 pin but one is without plug) connector as I added the photo. Just to be clear which wire where connect the second junction of connector is colorful wires. The second end of this cable is placed on the door. And one connector have many green wires and second way of connector is with colorful wires too. And these colors are not the same. :-(
I am sorry my English, I do not know how I should explain it.
The wiring diagram for sliding door will be very helpful for me now.
I am waiting for your reply.
Have a nice day,
Pawel

This looks like the left door, so I am attaching the wiring diagrams for this door.

Also, I noticed you have another post on the fuel door not opening. If you have these wiring issues, I would suggest fixing these wires before you attempt to fix that. These wires may be part of that issue as well so start with these and then tackle that issue.

Also, you may have to solder some wires together, so I am attaching this guide that shows how to solder properly.

Clearly this is a light socket so while the issue is different Ryan does an excellent job in showing how to properly put two wires together.

Please let us know if you have other questions. Thanks

KASEKENNY1 - Thank you for your reply. I mean left door. :-)
But I cannot find there (as I remember)13 green wires in 22-pin connector, which one is placed on floor door entry and the second 22-pin connector is on door placed, next to the speaker.

I checked it again and disconnected all wires from the car. Both end with 22-pin connectors of these wires are not the same (for eg. Yellow wires are place not the same pin). I don't know which green wire of all 14 pcs green wires should be connected to which pin number of 22-pin connector?

Okay. I think I am getting on the same page as you.

It looks like there are 3 green wires that are broken off in the connector and you are not sure which one of the wires goes to each place in the connector?

The issue we are having is these are inline connectors and not connectors that plug into a module?

If they are inline connectors, then we are going to have to trace the harnesses in both directions from this connector and find what they go to. This will tell us what wiring harness we need. These connectors and wires are not matching the sliding door circuits which means even though it is under the door it doesn't go directly to the door. It may have sliding door circuits in it but it is not for the door modules directly.

So, let's start with tracing these harnesses to see if we can at least find one end of where they go, and we will have more to go on.

Yes, there are exactly 4 wires and I do not know which one goes to which pin no.
"The issue we are having is these are inline connectors and not connectors that plug into a module?"
- We don't understand each other.
It is part no 72584-THR-A111. There are 8-pin connector (2 pins are empty) and 22-pin (1 pin is empty) connector one side of whole cable (let's call him beginning) and 8-pin connector and 22-pin connector second side of whole cable (let's call him end). I mean about 22-pin connector. There is for eg. Pin no 1 (at the beginning) which goes to pin no 16 (at the end). Pin no 2 goes to pin no 6 other side. But I am not sure about 4 pcs of green wires. I need pinout this whole cable (21 wires + 6 wires). The wiring diagram for left sliding door is needed. Not only for the left door but for connection the car with left door too.

Okay. I think I got it. That is called the Cess assembly and I am attaching the wiring diagram for just these connectors. As you will see there are quite a few green wires. So, you will need to match up the broken wires with the diagram on the end of the harness that is not broken.

For example, you take one of the broken green wires and go to the other end and find out what cavity that is in on the other side. Then look at the diagram and match that up to find out what cavity it goes in on this connector.

Thank you for your picture. But it is only one. I mean about 22-pin connector with 14 green wires. I don't see 14 green wires on your picture. Could you please add more details, more connections, wiring?

Yes. Clearly the wiring colors are not adding up. So, what we need to do is go to the end of the harness that connects to the sliding door control module. Trace the cut wires back to this connector to find out what cavity they are in. Then use the diagram below of the connector to find out what circuit that is. Then refer to the wiring diagram above to find out on the connector that has the cut wires, what cavity that circuit goes to. Basically, you need to use the side of the harness that still has the wiring attached in order to figure out what circuit it is. Then you can place that in the correct cavity on the broken end.

Success :-)
I found the right position for all green wires. It is A and B connectors. B connectors pin no 1 goes to A connector pin no 11, B2 to A10, B3-A9, B4-A8, B5-A3, B6-A2, B7-A1, B13-A13, B14-A22, B15-A21, B16-A20, B17-A19, B18-A14, B20-A4.
After correct connection all starts working! My fuel fill door was not working too, but it starts working after sliding door connection :-) It was for me surprise :-)
Thanks a lot for your help :-)

Oh wow. Great info. Thanks so much for coming back and updating us. Great work in figuring that out. I am not sure someone will have the exact same issue as this, but I am sure that your process will help others for similar situations.

Thanks again for continuing to use 2CarPros.

It is not 100% success. I was at official Honda service in my city for HDS connection and I received one fault DTC B1142 - I cannot set window position on rear left door from driver's door switch. I can set window position only from this LR door. I do not know what is wrong now. Maybe some wire in 72584-THR-A111? Or driver's switch? Do you have any idea? Or wiring form driver's switch to rear left door?

I doubt that this is related. I am attaching the testing that we need to run through to find out. However, if it is not related then we are going to have to get a new post started for that issue as we need to keep them to one issue.

Run through the testing below and let us know what you find. Thanks

Thank you for your tutorial. I found the problem - It is the switch for LR window door. I replaced it with a new one and all is okay now. :-)
Thank you for your help.
Greetings from Poland:-)
