V50 CEM Repair Terminal numbers
 

Hi All
I have had an ongoing saga getting some repair terminals to replace the Data circuit pins on the 3 plugs that plug in to the CEM
I also changed the Housing and terminals on the Accelerator pedal.
I went by previous information on here and ordered the CEM terminals under Number 30656678

I ordered 7 of these from Volvo and when they came they were the wrong ones. Volvo reordered them in case the wrong ones were in the "Bin" . Same incorrect one arrived.

Checked via Sweden and they gave another number 30656698. Very similar so I wonder if the number on this forum has been miss typed and then just copied.

The correct numbers for everything are below

8690595 Accelerator plug housing x1
30765498 Repair terminal for Accelerator plug housing x6
30656698 Repair terminals for CEM x6 for Data and x1 for accelerator signal wire.

CEM Plugs terminals changed are in picture below plus I changed the accelerator signal wire which is Green plug terminal G31(white wire)

The Green plug is shown in the photo below. The Blue and Brown plugs look similar and use the same terminals. The black plug is for the accelerator pedal.

As an FYI, my local Volvo dealer in Maidstone said that part 8690595 (Accelerator Plug Housing) is no longer available. The other parts are all available with UK stock at £4.38 each.

I have a similar issue on an S40 so will be trying this repair soon.

Hi


Did it work??

I want to try this on 2010 xc 90. Do you just pull old terminal connections. They come out of connector by pulling out? As per Clan's directions?

Have you done this repair? Meaning is the repair terminal PN 30656698 the right size? No offense - how did you know that PN 30656678 (Clan's suggestion) was the wrong size? Thanks in advance.

Hi

As explained earlier,
I originally ordered 7 x30656678 as per Clan's post.
They arrived and were noticeably different to the ones fitted to my car.
I explained to the supplier the problem. He ordered another set from the Volvo system just in case they were the wrong parts in the bin. The same terminals arrived and luckily I was able to return them and they refunded me for the parts. I did a bit more delving on here and kept getting told they were the correct ones. I contacted another dealer and they contacted Sweden who then gave me the number 30656698. I then ordered 7 of these on the provisor that if they didn't fit I could return them for a refund. They arrived and they did fit my car.
The photo shows the 30656678 with the red wire and the other is one of my terminal actually fitted to my car.


I then contacted the dealer again and they sent a technical request to Sweden.
The response from the dealer.

Photo of the bag the new pins (30656698) were in, that arrived and fitted my car (2005 V50)
Since fitting all my communication errors have reset and not come back (just over a year now)

On the parts list the dealer had he couldn't confirm which numbers were correct however when he contacted Sweden they supplied the correct number, which I then ordered. If you are worried or unsure ask the dealer to contact Sweden for the correct part number in case it is different for your car

Also a bit more history

You wouldn't happen to have one (of the right ones) that you can measure the dimensions of?

I'd rather buy the raw terminal sleeves from an electronics webshop and make my own repair cables rather than buy from Volvo with that insane price markup.

You happen to be very lucky.
I have just found one of my original ones I removed.

The square section measures 1.9mm x 2.36mm
Length is as in the photo

I am an electrician and would usually try and source the terminals separately but for the cost and ease I would still buy these from Volvo.
They come pre crimped to about 6" of wire.
So with the Volvo ones you can be sure the crimp is correct and good, the length of wire is ready to solder to the car wiring.
You would also need the correct crimp tool
And you can be sure they are actually the correct terminals for the housing and will correctly lock into the plastic housing securely. It would be a shame to buy terminals, have the hassle of fitting them and still have issues ??? Even volvo have so many different terminals and many look similar but are slightly different to each other.
I was also told these terminals are an "upgrade" / "Higher spec" from the originals

Thanks for getting back. I didn't see the photos that you mentioned

Hi
Photos are in the first post in this thread.

I also posted a link to the thread with more photos

Might be worth reading through this thread and also the one in the link then you will have all the information I have.

all this information I have posted is for the V50 and relevant to mine in particular (2005) I have no idea if any other cars/platforms use the same terminals or plugs and sockets. You will have to find that out. The dealer said they do many other repair terminals so I assume this one is not a "standard" terminal across the different platforms.
