No electric power in the dash

Yes. Same pins but I just want to be sure, you touch one lead to the pin and the other to a known good ground. If you have continuity or resistance then you have a short to ground. Then do the same to the other pin.

I am sorry. I was not clear. I want you to check each pin, 6 and 11, for continuity to ground.

Meaning touch one lead to pin 6 and the other lead to a known good ground.

Then touch the lead to pin 11 and the other to a known good ground. You should not have continuity. It should read OL on your meter. If you have resistance then you have a short to ground on that circuit.

Hopefully that makes sense. Thanks

Okay. It looks fine. That is the ground through the modules so it is not shorted to ground.

Can you recap where you are currently? Do you still have the U codes that you had prior?

I suspect there is an issue with the BCM at this point but we need to run through this testing to confirm it. It looks like you are going to need to run a network test but take a look at this info and let me know what you think.

Thanks

Okay. That is good that it is the same codes. So the network test is not something that we can do. It is a scan tool function but it is not something that the generic scan tools will do. This is an OEM or equivalent tool.

Take a look at the attachment below and it is M2 that talks about it. What I would do is just check around for a shop that has a tool that can do it and just have them run through this testing and pay the diag charge rather then buying the tool. Unless you are going to be doing this type of diagnostic work more frequently it really is not worth buying. They are normally a few hundred dollars at a minimum and you will pay less to have a shop do it as you will likely not need to do it again.

If you want to purchase one, then just make sure it is capable of running CAN network testing. You may want to call the company and ask just to make sure.

Let me know if you have questions on this.

We actually have a video on this. Here is a link:

However, based on your codes, I am not sure you need it. Basically what the U0140 in the ABS is saying is that it is not getting the proper message from the BCM.

This could be due to the communication network, the BCM, or the ABS module.

If you read through the test and make the assumption that the BCM will pass the network test which means it is not a wiring issue or other network issue then it leads you to replacing the BCM after you answer the remaining questions.

So you can get this tool as it does a lot but replacing the BCM may be the solution to these codes. Depending on the price of the BCM, I may just go with that rather than a scan tool that you may not sure all the time.

Run through the testing and confirm you are seeing the same thing.

Unfortunately there is no one source so what I would do is just do an internet search because I suspect you will find a company that can send it to you already programmed. This is pretty common for these BCMs and PCMs as they are pretty commonly replaced.

Please let me know if you can't find anything and we can take another course of action.

I think the issue you are having is the body control module is a pretty generic term. On your vehicle it is called the smart junction box.

Take a look at the info attached that gives more detail on this.

Those are not identical part numbers but more than likely there was change made to the part and when that happens they change the part number slightly.

I suspect they are correct that they are interchangable. However, they should be able to confirm that by checking that part number.

Take a look at the diagram for the location of this. Thanks

There is a process. You need to upload the current SJB info and then put it into the new one. You can do it when without uploading the info but either way it requires a scan tool that is capable of performing this function.

Attached is the process that you will need to follow. If you don't have a scan tool then we will need to find a shop that can perform this for you.
