You can try this (I believe it works for MCC, not ECC, so if it doesn't work its dealer only, sorry):

Also your volvo should be able to diagnose several problems on its own. To check if it has a code start with your car off (key in position 0) Then move forward to either I or II and look at the REC button on the climate control, it will flash one time if there's a code. If it flashes push the REC button twice, and only twice, when the light flashes and within 2.5 seconds of turning the key. The REC light will flash corresponding to whatever code it has. The code is three digit and the car will tell you one digit at a time. It is on for one second and then off for .5 if its counting up (so if the first number is 2 you'll have one second on .5 second off one second on) Then when it pauses for 2 seconds its switching numbers. After it finishes the first code (remember 3 numbers to a code) it will be 5 second delay between codes, if there's more than one. Therefore if you get the code 2-3-1 and 1-1-1 you'd have this sequence : 1s on, .5s off, 1s on, 2soff, 1s on, .5s off, 1s on, .5s off, 1s on, 2s off, 1s on, 5s off, 1s on, 2s off, 1s on, 2s off, 1s on ...

If you're not driving it "like its stolen," are you really driving?
