I recently purchased a used 2006 Volvo XC70 2.5T that had been sitting for at least 2 years and just needed some TLC.
It is missing the ABS Module, so of course the ABS light is on. After replacing a faulty battery, numerous Bulbs throughout, some basic maintenance and getting it running well and smoothly, with all electrical power options working, it is currently stuck on 105,217 miles and showing the following error messages, that, I believe are related to the missing ABS Module and that it was not running for 2 years or longer;
9999 Miles to Empty
Power System Service Urgent
Engine System Service Required
Brake Failure Stop Safely
Alarm System Service Required
Bulb Failure Position Light
I already ran my own OBD II scanner and was not able to clear or erase any of the error messages.
I believe I have no choice but to go to a Volvo Dealer and pay for the Diagnostic VIDA DICE Service which, will hopefully clear all error messages.
Any other suggestions?

 

1. Charging system problem - could even be someone put the wrong alternator in. (that does not have a LINBUS compatible regulator)
2. What engine codes are present?
3. ABS module is missing
4. Probably has a bad backup battery in the siren module and needs a new siren module to fix. (or some rig with a replacement backup battery)
5. There are 4 rear parking lights, 2 on each side. 1 or more is not working or they are different brands of bulbs

 

Thanks for the reply.
I hope your answers are correct. Not all that concerned about the rear parking lights as they are all working, nor the alarm siren battery since the siren is working as well.
The alternator might be the power system service issue.
The ABS ilight is obvious because there is no ABS Module, but again the car is running fine and the brakes are working fine.
King Regards

 

Hoonk,
The Bulb Failure Light Position turned out to be the right rear bottom tail light assembly that has water/moisture and it burned out the side marker(4)Diodes part.
The remaining error messages will need to be addressed with a VIDA DICE Diagnostic Tool.
Thnx

 

The Check ABS Module warning was periodically displayed in my 2007 XC70 and finally turned in full time. I identified the problem as a defective computer control board in the rear axle, apparently a common problem for this model. I had the board rebuilt and the problem went away. It is important to get this taken care of because this board controls a lot more than the ABS warning, as you have found. I give the rebuilder my shop chose a "C-" as the ABS warning still) flickers occasionally and the radio sound volume stopped functioning. In retrospect i should have chosen the rebuilder myself, as there are a couple you can find online who fully understand the problem. I have posted in this issue in earlier threads.

 

Ccalberti,
I’m not familiar with the rear axle computer control board. Please provide a picture and the Volvo Part#.
Thanks,
