Average Mileage: 122,448 mi (60,000 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.

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

    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.

    My ABS and TRAC lights have been on and off for the last couple of years. With the impending snow storm, I knew I needed to get my ABs repaired. The dealers quoted me around $800. I read ALL the forums and watched all the YouTube videos and they said it has to do with poor electrical connections inside the sealed ABS module.

    Found www.midwest-abs.com and did an ABS Module swap (versus the repair which was $10 cheaper). Since he sends the E-5 socket (would have cost me $14 just for the stupid socket) and offers lifetime warranty I figured I had nothing to lose. BEST DECISION of my car's life. Module came in the mail in three days, I followed the youtube video and had everything done in about 90-minutes. Easy peasy and my ABS and Trac lights went off. The snow storm hit today and my ABS was working great as I was slip sliding around the city! Give it a shot...the dude, Matt is awesome. https://www.midwest-abs.com

    Leads in ABS module have been oxidized; re-solder or go online to find one of several companies who specialize in repairing this part.
