Volvo S70
Report: ABS Light Due to ABS Control Module Failure
Volvo S70 Problem
Model Years Affected: 1998, 1999, 2000
Average Mileage: 128,333 mi (80,000 mi - 231,000 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 AND TRACTION LIGHTS COME ON AND OFF...ENGINE LIGHT IS ON. I WAS TOLD THAT THE OXYGEN SENSOR NEEDED TO BE REPLACED AND THAT SHOULD FIX THE PROBLEM---IT DIDN'T.
ARE THERE ANY RECALLS FROM VOLVO ON THESE ISSUES

Matty Moo repairs these for about $80 and will send you a one with a tool and instructions and you'll need to send your back after removal as core. Put a shim to flex the electrical connection and see if the light goes off and if it does you know it is the ABS. At this point the broken solder joints has been temporally be flex to contact the circuit board. Not a permanent fix but it is working. For safety purchase repaired Module.

Randomlly, a whirring sound came from each wheel when brakes applied. ABS light would come on, stay on for a while, then go off. Shop found and replaced defective rear wheel sensor module which did not correct problem. Then replaced ABS Control unit which corrected problem

ABS LIGHT STAYS ON CONSTANTLY. THE SPEEDOMETER AND CRUISE CONTROL WORKS OCCASIONALLY, SOMETIMES WHEN I FIRST TAKE OFF IN THE MORNINGS.

ABS light will not go off. Speedometer works intermittantly.

ABS light on, speedometer stopped working. replaced ABS and speedometer now works but ABS and check engine lights come on for a few minutes before one or both go out. replaced with a re-built ABS module to save some cash, so maybe that accounts for the erratic light behavior.

same as above and need to get it fixed!!! We're going to try to re-sauder the pins in the ABS module ourselves. Go on youtube and a reputable Volvo guy Matthew can show you how to get the ABS module out. You can buy a new one, after market, refurbished or send yours in to get fixed...all much cheaper and under $200. We'll see if we can sauder and clean the pins, otherwise, we'll prob. buy a refurbished one. We're looking at FCB euro or groton.com, there are lots of places to look for them.

Just bought the car. Driving along and Check Engine and ABS lights come on. Brought to independent mechanic and he said to replace it $914.

2nd owner and the ABS and traction control lights are always on. The light does not blink as it should when I turn it on. My Volvo tech said that this module also affects power and economy, not just braking and traction. The on-board computer uses wheel speed readings from the ABS module to make the car run better.
