Swapping a used modules works, they aren't crippled by vin coding Topic is solved

Although ETMs (throttle bodies) sometimes are sold with a note that they need to have software uploaded. This just is not true - at least for my 2006 S60 2.5T.

The throttle body does not sit on canbus. It has a connection that provides a pair of wires to drive the throttle stepper motor open or closed, and a ground and positive supply for use with the two potentiometer outputs that report throttle position. There are 6 pins in the connector and that accounts for them all. No software in here at all.

This afternoon, I replaced my 2006 Bosch/Volvo ETM with a Chinese 'clone'. I took a look inside the gearing box and was surprised and pleased to see that the system used magnetic position sensing instead of the resistive tracks that have failed on some throttle bodies.

I took a test drive and the car seemed a little smoother than before. I had left the key in position 2 for a couple of minutes which should run a calibration, but was not able to tell if it had run.

Anyway, clearly no software update was needed for this.

I don't think that anyone has stated here that a Bosch throttle requires programming. They only require a quick ignition on PosII calibration. Really good to hear that the Chinese clones use magnetic technology. Was it from OK Motors?

The Magnetti Marelli throttles up to MY 2002 are another story though.......

Your post is a little misleading.
I know for a fact that you can't just swap ETM's from one car to another.
I grabbed ETM at scrapper from a 2.4 n/a and swapped it onto my 2002 2.4 n/a and although the engine started it was still un drivable.
So i think it's possible when you purchase those units from Xemodex or that contactless Chinese unit the software is preloaded?
Am I missing something?

EngineeringBloke and precopster speak the truth. If you have an early P2, like up through 2002 with the Magnetti Marelli throttle, then yes it will likely need programming. I've never owned a so equipped car but I believe what everyone has reported.

But on the later P2's with the Bosch throttle, it's plug-n-play - no programming required. I can verify because I've done it.

for my 2006 S60 2.5T. no software update was needed for this

As mentioned above, on 2003 and up it's a different throttle body that doesn't need programming. It is good you are pointing this up, because it's good to know that - unfortunately - the Bosch throttle bodies also go bad, I think most likely after 2006 and up for some reason. I was reading a site with car reviews, many 2006+ owners did pay a hefty sum at the main dealer to have their TB replaced - when in fact they could have easily just swap a used one from 2003(?) up (better go with a similar year)
On 2001-2002 a swap with a used TB may or may not work without programming, it will depends on the serial numbers, software version, etc. For some people worked plug and play, but for most it didn't and programming is not really possible as the main dealer usually doesn't touch a used part.

The MM ETM and where it appears is documented here in the 'ETM ROOM"

I have a 2002 Volvo C70 and I need to replace my ECU since I have 4 injectors showing open. Can I use a different ECU from another car same model?

Thread appears to be old but here is something to think about:
Swapped an 04 XC70 refurbished broken ABS module with an 03 XC 70 and check engine and light went out, pedal/brakes/abs pump all work fine BUT now there are a plethora of new codes:

ABS-0114
ABS-0130
ABS-0133
ABS-0139
ABS-0140
ABS-0076
Last one is faulty configuration.

Brake pedal sensor was replaced as well.
