I have bought a elm 327 interface to use on my laptop. I have installed easyobdII version 2.2
I have succesfully linked the interface with the computer.
When i link to my 55 plate citroen C4, it say linked, then "car bus ok". The next step then stops and says "no power/vehicle response".
The program then stops scanning.
Does anyone know why im having this problem and have any idea on how to solve it?
Thanks for reading

With 55-plate you mean model year 2005? That should be compliant, even when it's a diesel. I suspect your interface is the problem. Check it on other known compliant cars.
Petrol passenger cars 2001 and up. Diesel passenger cars 2004 and up.
What elm scantool are you using? Is it a name brand or one of the cheap units? A lot of the cheap units have issues communicating with some vehicles.

With interface I mean the elm 327 cable/interface.
Only solution is to buy another one.
Was the car on when you tried it?

I bought a cheap one, too, and it doesn't work with my Mazda6. It does work with two other cars that we have at the house, a Toyota Corolla and a Honda Odyssey. I need to try it in another 6 to confirm it's not just mine, but apparently different cars react differently to cheapo OBD2 readers.
