V70 2005 Canbus problem?

Post by Eemeli »

Hello
Having a pita-issue with a Volvo Im working on. I have engine warning light on, as soon as I open either of my front doors. Light stays on when I start the car, also srs-warning comes up. No fault codes present. Im assuming the light comes when CAN is activated when opening the door. I measured voltage from the Green and White can wires near cem, they point 1.2v each, so I guess I have shortage between them somewhere. Anyone have any ideas where or how to start ruling things out, or any common places where the wires might be shorted?

I don't understand, what is the problem you are trying to solve? SRS blinks when VIDA connects to the car. Do you get the yellow triangle / door open message with the door in fact closed?

So the problem is this. Car isnt running, power is off, key is in my pocket. I open the door and immediately engine warning light comes on. When I insert the key and turn power on, the Srs fault comes up on the display. Nothing else is wrong, the car works fine and everything works, but I cant get it through the inspection because the warning lights are on. And No fault codes are present,just the warning lights.

You need to erase the SRS code. It lights up CEL even if the code is inactive.
