How to fix newer Volvo ABS module warning light caused by temperature or vibration effect on ABS module inner contacts. This is not the “Classic” broken welding problem. Newer ABS modules contacts are not welded. they are pressed against narrow holes in the printed circuit. The mechanical pressure ensure the electrical contact for a limited period. But time,temperature cycling and vibration cause these contacts to fail eventually. The fix is just to open the module and bend all the pressed contacts to restore the mechanical contact.

WTF? From what I could see you didn't "solder" the pins back onto the PCB?
Go downstairs.
Did this to my unit, on a Volvo s60 2005. Worked like a sharm and I returned the new one i ordered, thank you!
Is there a video on how to remove it in the v8? The module and pump are behind the battery and PITA to remove
Крышку снять не дано? Нахуя так курочить, там же на герметике все сидит, срезал герметик по периметру и делов-то. Автомобильный садист
It worked perfectly for my 2005 v70 with BCM 0070 code. Thank you!
December 2017. I was skeptical watching this. I thought, he did nothing to the board. On another video, someone said…I have nothing to lose and everything to gain…..So I tried it. It worked like a charm. I moved ALL connectors in the back, not just the few he did. Anyway, glad to have my ABS and AWD back again. I didnt butcher the back though. I used a dremel to remove the silicon bead along the edge, then gently pry up the backing With some effort, it worked and I hot glued it back after. Hey guys, no need to name call. Just a different approach. Its the fix that im interested in..I will make the choice on what is best approach to remove the cover. Thanks for the tutorial. You saved me TONS of money on this repair.
Would this cure "Anti Skid System Service Required" message?
Thank you so much for this video, I followed your approach and fixed it perfectly, as it failed the M.O.T due to the ABS light not going off, even though the fault was intermittent, which included warnings of "Brakes need servicing" or "ABS requires service" "ABS temporally turned off" "passenger air bag off" no need to solder the pins, so small anyway, and more likely to cause a short due to the tiny soldering points !! unless you are fortunate enough to have 20-20 vision and a very fine soldering iron !! and at the end of the day it cost me absolutely nothing to fix, took me just 1.5 hours in total including taking the ABS off the car , fixing, and replacing the ABS back onto the car 🙂
Much more effective way of getting the cover off is to use a heat gun to heat the silicone around the edge and run a razor blade around to try to scrape out as much of the silicone as you can before heating it one last time and using a flat head to gently pry the lid off. Harms nothing and once you seal it back up it looks factory again.
Thanks for posting this. Your fix worked perfectly. Bending the pins slightly to regain continuity resolved the issue. I have three suggestions you might find helpful.
When cutting into the BCM, cut on the inside (closest to the cemter of the BCM) of the black silicone seal. Be careful to stay as close to the seal as you can.
Use bright and direct light. Light where you're cutting so you can see when you cut through the cover. This should help you from cutting the components or the board itself.
The pins seem to have a flat side and a rounded side. Bend the pins so the flat side tilts closer to the board. This will help prevent the pins from breaking.
Again, thanks for posting this! ! !
I have a 2004 volvo s60 2.5T. my problem is ABS light is on, Brake light is on and Odometer does not work. I did the video method of opening the ABS module and bending the poles, but did not fix my problem. I was wonder if any of you had the same problem than me and fix it, also I was thinking of soldering all that pins too, but I am not sure. Any suggestion with be helpful. All the ABS fuses are good and get power.
