P2 (S60, V70II, XC70, S80, XC90)

Hi,
My problem is more difficult I think,
I change head lamp option from H7 to Bixenon,and commit changes,
After rebooting, CEM looks like dead, but I have new lights v:D,
I try relod or recover CEM bbut with no lack.
Car is now blind.
Is there anything I can do now??

@TAXI-VIP-CIX pin decoding should now be possible with Vdash. But I'm not sure if your adapter works for this. Also don't even think about using your Vxdiag for anything else than diagnostics on your car. These adapters are absolute unreliable garbage when it comes to coding/programming and have a really high risk of bricking your car.

@DarylDaryl the two ECM codes are usually the result of a dying ETM. Get a professionell rebuild for your ETM or a new one. If you replace the ETM you need to clone its software with Vdash. There are at least 6 different part numbers for this ETM that are all compatible with your car. A good rebuild consists of new potentiometers, new bearings for the butterfly and several new components on the PCB.

@rbo Thanks, only thing we can do is wait I guess..

@Olo Check/clean the tmap sensor at the intercooler. Do a smoke test of the whole intake, on all charge pipes and the intercooler. Also check the fuel lines for leaks. You have either a boost leak, a clogged/defect tmap sensor or too low fuel pressure. Depending on your milage it could also be a dripping/ leaking injector.

@David-B-Seres those mirrors/UEMs are not compatible with your car. Look up the correct part number for your car in VIDA. It should be 30658231 or 30658232. Compass is not possible for your car. You also need to clone the software of your original mirror to the donor part and change the car configuration to automatic dimming mirrors with Vdash which requires the CEM pin.

I have too old S80. The airbag unit has been replaced; the old module is dead (original module number 0285001258 and its not repairable). The numbers on the unit currently installed are: 8645271 0285001254.

This unit is now throwing the following fault codes: SRS-001C (driver's airbag stage 2 resistance too high – the car has a single-stage driver's airbag), SRS-0024 (passenger airbag resistance too high – the car has no passenger airbag), and "incorrect ID" codes for all side impact sensors (SRS-00B2, 00B7, 00BC, and 00C1). Finally, there is a configuration error code: SRS-E0.

Is it possible to load the software specific to this car onto this unit?

I found in the VIDA spare parts diagrams that the car's original module is replaced by the very one currently installed in the vehicle. It also required replacing the connector housing due to the different shape. So, I believe suitable software must be available for this car and unit.

I’ve sent a message to the help desk, but there’s been no reply.

Bought a new cluster unit this one seems to not have the issue, but now the retrofit software is not working on this cluster.. (Unable to load this software, because it's been used for different unit.
If you wish to load the software into different unit, please contact the helpdesk.)

Im not sure how to get the right retrofit software to pop up in the software tab. The other one just showed up at some point but not this time.

@Jovatech Vdash won't be useful for this, as it lacks the needed diagnostic commands for your car. You will need VIDA for this.
You basically disconnect the battery, change the CCM, reconnect the battery, and then connect VIDA and navigate to diagnostics/vehicle communication/CCM/advanced and use the 2. option. Not sure what it's called in english. Something like self adjustment of flap motor/actuator stop.
That's it.
If your old CCM is still communicating, you can clone it Vdash, but as you want to install a used one, the software for it to operate should already be present in the replacement.

@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

@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.

@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 🙂

@Zwergnase you will also need add the ABL switch to the center console.

@SU-AM Removing the pressure sensor will drain the AC. You will need to evacuate/empty to whole AC via a vacuum pump and then refill it with R134a without letting any air going in the system. I can't tell you the exact amount of refrigerant. Stay away from those DIY refill sets. You will make more damage than you can even think of by using this crap. Fill in to much and you damage several parts of the AC. Fill in too less and the AC won't work and you will also create damages.
Visit a garage that has the special tools and experience that are required for this and let them do it the proper way.
