VOC (Volvo On Call) removing

[Dougray]

I completely solved the problem with Volvo on call error. you need to replace the battery that is inside the VCM

When you replaced the battery in the VCM module, did you need to do anything else? Or did the message just go away. I have replaced the battery on mine today and cleared the related  fault code, but v2109 backup battery component failure keeps coming back. Not sure if the VCM module is damaged (I was very careful with the connector and did not damage it) or the battery is a dud.
