@Libelix That will hurt your bank account. New VCMs are really expensive.

You will need to revert all changes done with Vdash and OrBit. The CEM configuration has to be the one that is known to the VIDA/Volvo servers in sweden or the car will be blacklisted.
If the independent has paid for a VIDA license which includes software reloads he should be able to do this. But the price for the software reload will be the same or even higher than by the official dealer as the license fees are very expensive, and almost every software package has to be bought like a "spare part". Ask for an offer first.

@reeferjon What did you use to get this code? That's no Volvo/VIDA format. And that P200500 code is not present in VIDA for the ECM of your car. Scan the car with Vdash or VIDA.
Vdash is no diagnostic software. You can still try live data reading via the ecu diagnostic function of Vdash, but you will need to use a Super J2534 adapter or a really, really good DICE clone for this. Other adapters are to slow for this.
There should be at least 3 different ECM values that you can monitor. Demanded throttle position, and two values for the 2 sensors. Demand and sensors should show similar values.

You can also use VIDA, which you can get in the depths of this forum, and perform a throttle activation via the ECM to test it's function while the engine isn't running. I'm not sure if Vdash also has that function, as it is not made with diagnostics in mind and therefore lacks lots of such functions.

As your code seems to be airflow related, have you already checked your MAP sensors? Like this? Your car has two of these sensors. One in the plastic pipe between the throttle body and the intercooler. And one as shown in the article I've linked. Both tend to get clogged and create lots of codes like MAF errors or low airflow codes.
If there is lots of carbon buildup on the sensors, cleaning the throttle body and MAF is also a good idea.

Finally, I did it. Someone programmed me a universal sensor with the 31414189 protocol, and installed it and then used the program “TPMS L Without WBL, ICM reset”. I drove for about 10 minutes and the car made the pairing itself while driving. Thanks.

Ach stark ☺️

Danke dir schonmal für die hilfreichen Tipps.
Wenn ich aus dem Urlaub zurück bin, werde ich direkt das CEM checken und die Steckverbindung an der A-Säule höher der Klappe des Handschuhfachs hinter der weißen Abdeckung.

Werde mich danach nochmal bei dir Rückmelden.

Nejlepší cesta je zadat čísla řídících jednotek CEM, FSM, FLR, CVM, BCM pro kontrolu kompatability AI.

@T5-T6-Schnappi

Thank you very much for your reply and for recommending that I contact @VOLOK directly. I really appreciate your help!

You are a legend @T5-T6-Schnappi that worked and my car is working again 🙂

@Puppi

Hi, hat sich der Fehler bzw die Ursache in der Zwischenzeit aufgeklärt oder hast du (doch) mal versucht quer zu tauschen? Gab es noch weitere Symptome?

Mfg Tea

@330hpwagon I'm not sure if your car supports HDC. The official manuals mention HDC only from model years 2015.5 onward as this feature was officially introduced with the Cross Country models and is activated by default on these models only.
To use HDC you have to manually shift to 1st gear or R. You can't activate it when in D or above 7 km/h.
VIDA doesn't mention anything about specific hard- or software that has to be installed or that this function is only available from a specific structure week like other functions like ERS.
The DTCs in your BCM are also all yellow which means they are temporary/historic/not active while the others in red are permanent. The first one in the CEM is from LED bulbs at the license plate and can be ignored. The others should be the ones that you want to adress.

Why exactly do you even want to activate this function? I have a V60CC with this function and never felt the need to go downhill with less than 10 km/h.

@T5-T6-Schnappi Thanks for advice, i borrowed other cable and everything worked out. Also it works with different part/hardware numbers too( added picture). If it will be useful to anyone, it is enough to buy ETM by model year, the codes may differ.

@MarkusC30T5 Manuals don't have a TCM. So all related wiring for that can be removed from the car.
You need to ask the Vdash support if they can provide the required ECM reload (manual software) for you, and also if the configuration change in the CEM can be unlocked/activated for you.
This will of course cost you some money.
You also need to crack the CEM pin to change the configuration.

@Jcm89 a flush every 10000 miles is a little bit over the top. Drain and refill at this intervall would be more than good enough to keep the transmission happy.

As for the torque limiter. 5-speed automatic is limited in the first two gears. 6-speed in first three gears, 8-speed has no limiter. This is done to reduce wear on the differential, drive shafts and several other parts, but also to have enough traction.
Some tuners offer to remove this limiter, but it has more negative than positive effects.

@VolvoAugust The only way to get the pin is on the bench. You won't get information how to actually do this in this forum. The guys that know how to do it, usually don't share their knowledge to the public.

Thank you so much for your answer! I was told that and it was werid when I saw the message in vdash.
I will contact the vdash support, maybe they can help me with this issue.

I would suspect a defect wheel speed sensor, corroded sensor ring at one of the wheel bearings, or low battery voltage.
Put the car on a lift and check the signals of all sensors with an oscilloscope. The sensors could still be working, but the sensor rings could miss one or more teeth which results in sending nonsense signals to the BCM.

@Cookie_69 wrong forum for such questions. Vdash won't be useful for any of your questions.
Engines with Bosch throttle body require a different ECM. Those ECMs are not compatible with your CEM, so you need another CEM and somehow adopt it to your car. And so on.... Absolutely not worth it. You will basically need to update your whole car to the electronics of a 2005+ Model.
Get the correct engine for your car, or scrap it and get a new car.

Hey, did you end up getting this sorted at all? I've recently acquired an XC70 P2 which is reading the same DD10 LIN Communication Fault. I haven't looked into the problem in too much detail but it's something I'm getting round to, if you did end up getting it sorted, any tips/things to check would be great 🙂

Thank you very much for the comprehensive explanation 🙂

@pvm I can't tell you if Vdash is capable to clone HCMs on SPAs. But you will see if this option is available in the clone menu. CEM pin shouldn't be required for this. Your ENET/DoIP adapter is perfect for software updates/cloning and recommended on SPAs. J2534 is only for older plattforms and also good for pin cracking on SPAs up to 2021.

You need a software update. Part number 32398268. Official VIDA subscription or trip to the dealer required. There is no other way to fix this.
