Report: ABS Light Due to ABS Control Module Failure
Volvo V70 Problem
Average Mileage: 148,800 mi (110,000 mi - 184,000 mi)
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 have been on and off for about a year, also the slippery road warning light and check engine also appear,and service light too.
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).
