I have a similar problem, I am going to assume that most of the lights have gone out and you are left with the check engine and a transmission service message. Check the OBD for the error codes and see what they say. If they are P0722, P1618, P1633 it is likely your ABS module. This module appears to have a life span of 5 years to 80,000 miles average before it needs to be replaced. Other symptoms of a bad module would be that the ABS light comes on while driving down the road. Than goes out on the next engine restart or two. Victor Rocha is reconditioning ABS modules for $125.00 and upgrading them to better than factory. There are instructions on the web of where and how to remove the ABS module. This is better than the dealer's new module for $995.00 plus installation.
I have had the same problem with my car for 3 months now. It is the ABS module that needs to be replaces. Ignore the stop ASAP light the brakes will still function as standard brakes. You just don't have ABS brake functionality or STC when those lights are on. Your car should still drive fine. Go on line and order a rebuilt ABS module for about $200 and the problem is solved. Hope that helps.
i had a problem in my S80 .Abs ,STC Brake failure,check Engine and speedometer all of tese didn't work , i just changed the ABS module...it's done now :) just perfect
not a volvo mechanic but on most american cars the abs and stc modules are in direct corilation with the cruise even though the cruise is most likely ran from vacume the disengagement is electrical.
the ring you mention removed is called the exciter ring and is a vital part of the abs system to work properly so have new ring fitted asap this is why abs light etc is on in the uk this would fail mot safety test i am surprised the garage?? did ot renew this exciter ring? knowing it affects the abs ie makes it none operational should it need to operate ? also if involved in accident? and car brakes are checked this serious fault may have an effect on insurance claim hope this explaines??
I had the same problem which was diagnosed incorrectly 3 times
Could be one of 2 things you may want to check
Have a tech read your codes
Have the ABS Control Module checked by a technician. If that is ok then make sure they look at the altenator
In my case, I was getting voltage spikes that were shorting out system controls -the ABS Control Module and the battery, etc. Once they put in a new altenator, the problem was fixed.
