Guys, My ABS module might have gone bad. I lost my cruise control and the ABS light is on. I seen where guys have sent theirs out to be rebuilt. I was wondering if there was a way I could find another one used and then take the car to a shop to re program the computer system. I have a body shop down the road that specializes in foreign cars, Audi, BMW and Volvo and Mercedes. I was told they have all the computer stuff to program all the cars....

Anyone have any ideas and or info on how I can obtain another one? I want to be sure I get one that matches my car make and such?

I can't get under the ABS module to see what model or serial it has? Any ideas? Possibly the VIN number????

Thanks for your help and assistance!

After doing some reading, I wonder if it's the Brake pedal position sensor but how do I rule either out? Also any easy way to get to the Brake pedal position sensor?

Thanks!!!!

 

Remove the negative battery lead unplug the sensor under hood and attach or hold a multimeter to the sensor fins. Put the car in neutral with the E-brake on and you or someone press down on the brake pedal inward and out ward ,then stop half way use the 20ohms reading setting, record the numbers on paper, get back to me ...or just pull it apart like i did .!! Check out my picture album I have a step by step instruction on how to remove and fix the sensor with lots of how to info..you could also try and start with a used one for 50-75$ if that operation seems a little much..if i had a used or new one the repair would have been a 10 minute fix ....but i say DIY its easy in my opinion

P.S get back to me asap i just had a night mare with my ABS lights...check my (ABSlights,ignition switch,ball joint,cooling fan,electrical problems,all repairs) post
--------it cost me 5$ to remove the ABS LIGHTS problem hunker down the post "its a big one!"read up to the last post please buddy!

my pet monster is driving wonderful at the moment !

 

How can you even get to this part! Between the ATF dipstick, the brake fluid reservoir and the other parts. I can hardly get my hand to even tough this thing! I think it is the brake pedal position sensor because I lost my cruise. I also lost my odometer also! Maybe a shop can do this and replace the part better than I can?

 

If you lost odometer reading that means BCM module is probably dead.

 

Just we're clear I only have no cruise and odometer when the abs light is on! When it's off I then have full function of both the cruise and odometer.

Thanks

 

that means that BCM is not completely dead.
When ABS light is on that means BCM module is not responding.
Engine ECU is also using brake sensor via BCM so it is not available and cruise is not working.

 

Oh ok! Makes sense! I ordered another BCM from Erie Volvo for $150. Said it had 80,000 on it. Hoping to get about 50,000 out of it. Now I need to find and purchase the E5 torx head

 

Sorry, I was at cottage for a few weeks. I was wrong boudlebug was right....hes the man on this post...2004s are very different to my baby

 

Sorry it was my abs module! It's replaced and all fixed now! Lights gone and my odometer and my cruise r back! God I missed the cruise control!!!!
Thanks

 

torontos80t62000, I've read you thread. Hope you've really done it and everything will be fine. But these problems are for 99-01 model years (we have some cars like yours one). 2004 is different.

 

Yes every car is different.......I was wrong on that one....but so glad you helped him get to the issue .. I totally agree with you double bug but I thought the 04s hardly had this problem.......nice one bug

 

Did you need to get it programmed after replacing with a used BCM? Was it driveable after replacing the BCM? @spankey @doublebug

 

no reporgraming. I installed it and off I went!

 

You just lucky. Config of donor car was the same as yours.

 

Um, yeah! I used Erie Volvo parts outfit out of NY called them told them my model, got one? Why wouldn't you match the car? Why take that risk?!!!!

you wouldn't request an S40 ABS module for an S80 would you?

 

I used p/n 9496931on my 2000 s80 . it was from a Volvo SUV.
