I don't know where to start on this , all I know is I need help or some guidance on this issue
I'm doing my best to stay away from the Volvo dealer .....

I bought this car for $1900 US , had a bad ABS module when bought ,
(the odometer was stuck at 207,513 miles ) (car also has DSTC)

So I replaced with a used module and had reprogrammed at Volvo)($313.00 total for code read and software)

I bought my own scan tool made by icarsoft which works great...and saves money and gas ...
so here the codes that were left over ....
BCM-0103 , BCM-0011,CEM-8D02, ECM-9400

I replaced wheel speed sensor and looked worn (see pic)
I am lost at what to do next (the wheel sensor code did come back briefly
today but stayed off when I erased the dtc...
the BCM-0103 code comes up after 50mph

anyway I am lost and need some advice... starting to wonder if
it's time to throw in the towel ....

 

Think I pretty much figured it out .....

I took another look at the service manual ...

it looks like it's easy enough to get to ..(I thought at first it was behind the booster for some reason...)

Anyways I will take a look at it in the morning,and check the connection

other than that ,I did find replacements for around $60 online ....
