Got a 2001 S80 in a trade deal and it runs great but it has quite a few Codes that pull up and I am having trouble with a few of them. Already fixed and cleared about 9 but having trouble with these....

6A01 Left rear door lock signal too high
6A03 Left rear door lock signal too low
6A02 Right rear door lock signal too high
1D02 Control module fault
1A53 Communication with PDM missing
1A05 X-Power signal high
1A06 Power signal too low
1A09 Power signal too high
1A5D Communication with ETM Missing

ANY help would be greatly appreciated

 

Just trying to figure out if it is worth putting any more money in, just driving it like it is, or put it up for sale as is before it becomes a money pit. New to Volvo and really like the car but not enough to go upside down on the repairs.

 

OK got it down to 2 codes left. 00D0 AND 00D1, Driver and Passenger seat belt signal missing. Looks like the SRS module in the console may be bad. Can this module be used out of another car or is it something the dealer has to marry to the car?
