ABS Light Due to Control Module Failure on Volvo V70

Problem Description and Possible Solution

The anti-lock brake system (ABS) Control Unit has a high failure rate. When this fault occurs, the ABS light will illuminate and codes may be stored indicating a problem with the ABS Pump Motor, or Wheel Speed Sensors, but the problem is the ABS Control Module.

Other symptoms may include an illuminated Check Engine and transmission shift light, and the speedometer may stop working as well.

Note: The brake system will operate normally however during a panic stop the Anti Lock Brakes will not work and the wheels may lock-up, causing a lack of vehicle control under these situations.

Abs light and Anti-skid readout is intermittent.
ABS light started coming on more often, but would reset the nex time you'd turn the car off. Bad connections/soldering in the module are to blame. Workaround that works in some cases (as did with me): put a spacer between the module and the ABS pump (used cardboard) that puts pressure on the ABS module casing and helps with the loose connections. Instaed of coming on once or twice a day, the light only comes on once or twice a month when it's very hot (100 F).
I replaced this myslef and it fixed the problem
abs light have been on and off for about a year, also the slippery road warning light and check engine also appear,and service light too.

Dealer says it needs to replace abs control Module for 1,800!
Had NO issues with my Volvo XC70 from 2003 purchase new until 2013, then battery kept running down and turned out to be the alarm system computer control [kept running when car shut off], repair cost at dealer @ $400; spring 2014 my husband went to start car and THUNK! - front spring broke, cost to replace both front springs by local mechanic =@ $400; August 2014 suddenly, while driving, warning lights came on- brake system, tranny, - drove home ok [few miles], hubby started it, all ok, drove few miles, warning lights came on, shut down & waited, started up, all ok. Getting new brakes at local mechanic, will let you know. My Volvo used to be garaged year-round but since hubby bought a new cobra look mustang a couple years ago, my Volvo sits outside April-October [he has 4 cars, bass boat, big tractor - fills our 5 garage spaces].
Exact same problem, but i have a 2006 xc70. Not sure if it's worth fixing, still seems like a gamble...what next sort of thing? In addition, my passenger window is not working properly, I need new tires, and headlight lenses are so scratched, it impairs illumination. looks like at least another $2500.
replaced ABS control module for $1,000!
uknown at this time lights keep coming on ,
