Yes only the one. A little black thing in a SOD323 case... And I think that there is printet B3 on it.. I think it is the same as DA15. But I need more to ordre it from a anyone

A BZX399C2V2 from Philips ?

Are you sure? Because DA12 and DA13 looks like a SOT-23 package with 3 pins from picture?
In that case they might be 1SS184 or HSM2694 or similiar...
Are any of those three pins short-circuited? Or where they go (if it is possible to track them?) Can you use a multimeter (diode test) and do some measurements?

Now I mesured the chip. It is NOT a HSM2694 since it has a common Anode, but The 1SS184 looks prommising :-) and yes it is the SOT-23 case not SOD323.

I keep working...

I cant get the toshiba diode in denmark, so I try the BAP70-05 insted

Thanks for now.

The left hand one on the CEM. If you put a finger on it and then operate the rear wiper switch you should feel it click if it is working.

Hi,
Is the CEM and ECU one and the same?

I was told by a local Volvo "expert" that the CEM is coded and can only be used on the same car. Is this true?

No they are not the same. There seem to be a couple of different model numbers for the ECU on the S40. I have tried the ECU from a 2001 1.6 S40 on my 1.9D and everything was fine.

What exactly are you trying to do?

...if you can locate the relay in the CEM just replace it you will need a soldering iron!...B2 on the wiring diagram leads to it...all modern relays are available on the internet outlets somewhere you just have to do your own homework..
