Vdash can't decode V40/S40 CEM pins. A VDD or Modunlock is needed for decoding through OBD. Alternative would be decoding on the bench. AI decoding might work but is currently unavailable. And don't use crap from Vxdiag for any coding operation, if you don't want to risk bricking your car. Use a good quality DICE clone, Mongoose Pro or Super J2534 instead.

@make-volvo what exact error codes are present in your car. Maybe your car was tuned/mapped by a former owner. This would trigger at least one of the following DTCs CEM-U030100, ECM-U032700, ECM-U032200

@VladGB ACC not working has nothing to do with this DTC. There must be some other DTC in your car for this. Most probably your FSM is misaligned and there should also be a DTC present for this.

@Bart This option should be also be available under the language tab in the top right corner, when you are connected to the car. More info https://svdns.info/2023/08/27/so-youve-bought-an-import-volvo/

Vdash can't decode your PIN.
You need a VDD https://d5t5.com/eshop/detail/87/vdd-volvo-function-extender or a Modunlock device https://modunlock.com/wp/shop/ for this.
Or you have to try again if AI decoding is available for your car, which currently is only active at D5T5 office hours Mon-Fri 9:00 - 16:00 - CET.

@raf1974 check your CEM for water ingress/corrosion.

@Mir-21 both voltages should show something around 12V when the ignition is on. Check all fuses and also the connectors and grounds of the ECM, CEM, SRS. Maybe something became lose in the event of the crash.

If I understand this article https://d5t5.com/article/srs-clearcrash correctly, you have to clear All other DTCs first.

@Mir-21 there is no way to disable or circumvent the immobilizer with vdash.

If all keyfobs for the car are missing, you can decode the CEM pin and IMMO pin and simply add new fobs to the car. (except keyless ones).

If the existing fobs don't work anymore, you need to replace the immobilizer antenna. Here https://parts.volvocarsofmarietta.com/a/Volvo_2010_V70-32l-6-cylinder/_51513_5697318/Ignition-switch/GR-366172.html?assemblySearchGuid=98B8BC63-0131-492B-97AC-D9261C5D2F42 you can find the part numbers.

If your car was involved in an accident, your car is in“ crash mode“ and won't start. In this case you have to replace all airbags that were deployed, and than you can use vdash to get your car back to live.

@joroartcorp the software of your original DIM was tampered to ignore the real mileage of your car, which is stored and read from several modules of your car, like ECM, TCM, DDM, PDM, CEM and most probably some more. Instead it shows some much lower numbers and has the DTC about incorrect software. During the retrofit this defective software was transfered to your new DIM. So you still have this DTC. If you want to get rid of the DTC, you have to revert to the original hard- and software configuration of the car and visit a volvo dealer to do a software reload for the DIM. Or create a support ticket and kindly ask the guys from D5T5 if they are able to fix the software for your new DIM.

@joroartcorp Vdash\D5T5 won't show you the PIN. No matter what decode method you use. The PIN is added to the vdash database once it's decoded, so you can work with vdash. If you need the PIN for other programs, you need to find other ways to retrieve it.

@Gorky571818 This code has nothing to do with your problem. There is most probably a CVM code for a misaligned FSM present in your car.

OBDlink does not work. Regardless what you try. You need J2534 compatible hardware.

@JONT3pro Nope. You need to add a resistor or use Canbus compatible LEDs.

Do the LEDs in the adaptor light up, when connect it to the car?
Where did you buy your adaptor?
Did you try a different USB port?
Did you try to simply reboot your computer, as Windows sometimes locks up certain files until you reboot it.
Did you use the correct connecting order? 1.Adaptor in the car, 2. Ignition on, 3. Cable in the USB port.
Do you have any third party anti-virus software installed? If yes, disable, or even better, uninstall it.
You can also try a re-install. Uninstall Vdash, reboot your computer, download and install a fresh copy of Vdash https://d5t5.com/sw/vdash.exe and see if it updates itself after starting it.

@Nilsco_91 Hallo Nils,
um als deutscher Normalo Zugriff auf VIDA online zu bekommen, musst du Betreiber einer Meister-Kfz-Werkstatt sein. Dann kannst du dich hier https://tis.volvocars.biz/main.do registrieren und bekommst im Tausch gegen abartig viel Geld Zugang zu allem was du suchst. Mein letzter Sachstand sind knapp 8000 Euro im Jahr, wenn auch Zugriff auf Softwareupdates enthalten sein soll, die natürlich jeweils nochmal extra kosten.
Grüße aus Berlin.

@evov and engine should not run when you connect vdash. Ignition needs to be in pos. II, ingnition on, engine not running.

@evov did you install the drivers?
https://d5t5.com/eshop/sw/J2534_Driver_x64.msi for 64bit Windows
https://d5t5.com/eshop/sw/J2534_Driver_x86.msi for 32bit Windows

@Ariot your computer needs to have a good internet connection while you are in your car.
To connect your car to the D5T5 app, you need a VDD Dongle, which has to be plugged in your OBD port. https://d5t5.com/article/vdash-vdd-dongle
To unlock your speed limiter, you need to decode your CEM pin first. Depending if your car is already an ICUP (Android Automotive) or a still a Sensus car, you can either decode it by brute force, or you need to buy AI premium pin decode. Modelyear 22 and newer are usually ICUP cars, so it's most likely premium pin decoding for you, as these cars can't be cracked by brute force. https://d5t5.com/article/volvo-cem-pin-code
