Hello my friends
Thinking seriously to take a bat to my wifes 2006 volvo S40.New battery New starter and I get the imobilser see manual,Anti skid service and passenger side airbag messages.Tried both keys,Done procedures as suggested by various experts.No start ARGGGG!!!I have noticed keys do not open or close car and alarm system does not activate although it did work before.Have to open car manually.Any suggestions would be greatly appreciated and you can actually save a volvo from murder.Thanks in advance

 

I would check your voltages at the new starter. What you describe is a low voltage condition. Given that you just replaced things that directly affect the voltage.

 

Thanks for your reply.Could a bad alternator cause this problem?

 

Yes, mine did that exact thing.
