#26 of 35 Volvo S70 Speedometer and Brake Light

#27 of 35 Speedometer and brake light
Aug 27, 2007 (5:19 pm)
My 2000 S70 recently has been displaying the red brake warning light(sporadically) and the speedometer will drop off to zero while driving.
Someone mentioned a sensor in the rear section. Is this easy to locate? Is it easy to change?
Another thing....when the brake light is on and I am accelerating from start, the car acts sluggish -almost like the brakes are engaged and preventing normal acceleration. Any ideas?

Have you been able to fix your problem?
I have a 1999 S70 and my brake light, and up arrow light come on and I have all the same problems you have described - the speedometer drops to zero, the computer only has dashes and the acceleration changes - sometimes it's much worse that others. Mine now happens all day long
The dealership connected it tot he computer and said I needed some patch and it fixed it for about 2 hours, but it has come back. The dealership thinks it might be the ABS sensor which is a $1200 part. I honestly have not gone back.

Most likely cause of problem is a bad ABS control module. I have two 2000 S70 GLT/SEs and both have experienced this problem after 100,000 miles. Dealer repair can be $700-1000. New Volvo part alone is $450-900.
If this is the problem, bypass the dealer and do the repair yourself for about $100. Rebuilt ABS modules are available for much less, and they are usually rebuilt better than the new units (new units have NOT been changed and they will still break down!)
Check out more info at these websites:
Vic Rocha (second site above) will rebuild your ABS brake module for $125 with a 5-year waranty, but you have to remove the unit, ship it to him and install the rebuilt part. It is not that difficult - my 17 year old son did it in about an hour. (It is possible, although not recommended, to drive the car while the ABS control module is off the car. See the websites above for more info.
You can also order remanufactured units from several places such as:
http://www.modulemaster.com ($110 + shipping / 5 year warranty)
http://www.bba-reman.com ($99 + shipping / limited lifetime warranty).
Both usually have rebuilt units available and can ship it out same or next day. You must return your faulty unit to them, since they will remanufacture it for resale. I have experience with BBA-reman and totally satisfied, but have talked to ModuleMaster and beleive that they are also OK. (I only chose BBA-reman because they were closer, so I was able to receive the unit faster with lower shipping costs!)
Note that Volvo used several different ABS modules, even on the same make and model car, so you will need to get the part numbers off of the unit on your car in order to make certain that you are ordering the right part. I used a mirror and flashlight and read it (backwards!) before I removed the unit.
Find a Torx E-5 socket to do the removal. They are hard to find, but using a 4mm socket (which is close to the same size) risks damage to the bolt head.

Wow, thank you so much for this helpful information! I know very little about cars coupled with the fact that I'm a woman, I always feel like I'm getting ripped off at the body shops. Actually, I KNOW I am! My 1999 S70 has the exact issues that are described above, blinking arrow light, check engine light, ABS light, Brake light all come on at various times. I took my car in to a Swedish Auto specialist in Venice, CA and after $700 he told me the problem was fixed and the sensor just needed to be reset. Well, that lasted for about 2 months and now its back on! My brakes feel sluggish at times almost like driving with the parking brake on and the speedometer remains at 0 and the computer just has dashes. Anyway, I hope replacing the ABS module will work and the car will run smoothly again. Just wanted to say thanks for your very thorough and helpful post!

i am having almost the same problem that the others have. speedometer drops to 0 and after while comes back on. i have a check engine light on, SRS light, ABS and BRAKE come on but after a while it goes out and i only see check engine, and SRS lights on, but when speed drops back to 0 and i see dashes instead of miles on the cluster, the BRAKE and ABS comes back on. I just give up. This car will empty my pocket if i wont find a cheaper solution. Can some one HELP!!

i got my abs module fixed for $100 and now everything is working properly.
If you are experiencing speedometer lose and SRS light, ABS and Brake light is on and also from time to time you experience the cruise control not to work and then come back to life, KNOW FOR SURE THAT IS YOUR ABS Module that's not working you have to fix it. HOW?
ANSWER: go to www.modulemaster.com
they will fix any kind of module for 100$.
IT IS TRUSTED SITE. its not a scam, its just a good deal thats all.
instead of paying $700-$1000 for a new module, you only pay $100 plus shipping both way. they will also tell you how to locate it and take it off.

Just wanted to say that my 2000 S70 had the exact same problem and the information in this forum as well as the related links was VERY helpful. I was able to order the new ABS module from IPD and install it with no issues. I have no more symptoms... problem solved!
#34 of 35 the brake and abs module problem
Feb 10, 2012 (7:08 pm)
I have had the same problem with the brake light coming on, the speedometer not working and so forth. By brother in law is a mechanic and tried to help me take it out to mail in, but he said we would have to drain the brake fluid and when he researched it it seems you need volvo equipment to do it. How did you do-it-yourselfers do it??

1st, let's start with some basic: I have 98 S70, automatic, non-turbo, w/ ABS, w/Traction Control (TRAC) with a manuel over-ride switch on the RS of dash panel (to over-ride for TRAC).
Do you have same thing? if not what do you have??
