      2007 V70 Anti-skid warning affects transmission?

      Hello. I have a 2007 V70 2.5t. FWD, 86k miles. About a month ago the anti-skid service required warning came on, and has stayed on. The antilock brake system seems to actuate sometimes for no reason.
      Also, since then at times the transmission will hang in first gear for far too long.
      I cannot say that these two problems always occur together, but they do usually occur in close proximity, and the likelihood of occurrence is much greater during the first mile that the car is driven in the morning.
      Are the two issues likely to be related? Or two independent problems. Any input appreciated.

      The TCM will hold gear longer on from cold starts, as long as certain parameters are med, to increase engine and trans temps to nominal levels. The ABS issue is probably a defective ABS module, which as far as I know can be soldered and repaired. I doubt the two issues as related directly, but they both communicate om the CAN network, and glitches do occur.

      I'd recommend pulling codes, and getting the trans oil flushed or changed.

      You can't repair a 07 ABS module, requires replacement if that is the problem, could be something else.

      I'd like second this. Make sure you clean it too. my friend and I just did a Bosch ABS Module on a Mercedes-Benz that was completely inoperable, and had good results. It is a little bit hairy but it can be done.

      We love our broken cars....my 745 had her rear springs zip tied in place for a while. Also could be that we cannot afford to have our cars down and that the gent here doesn't own a second car to jump into if the daily is wounded. My father drives his fancy shmancy 535i with a CEL and rough idle for over a month....I'm pretty sure it was fine just like this mans V70 is probably fine and is fighting the electrical gremlins.

      Thanks for the helpful reply. My shifting issue is such that it is way beyond the typical cold operation. I will change the fluid asap.

      Can I do this with a certain reader, or does it have to be the dealer?

      Many readers claim to be the best, but I've yet to hear of one that reads eveything Volvo's VIDA/DiCE does. It's worth paying a symbolic figure to have them read at your Volvo dealer, but make sure you get a printout of the codes, and ask for an explenation of each code. If they won't give you that, leave and go to the next dealer.

      With a 2007 there are only certain readers that can be used but this one needs to read on VIDA, (dealer, or someone who has a unit).
      You can buy one of these for around $150 or so, you need a laptop with Windows 7 Pro for the best results.
      Will pay for itself by not going to the dealer ONE time!

      yes you can. Well I can anyway, maybe you can't.
      besides, with intermittent engagement it sounds an awful lot like a wheel speed sensor, not a module problem.

      They're only $70, and you don't need a win 7 machine I posted a VM that is OS independent in the OBD forum. I use my linux machine.

      No every 07 ABS (BCM) module is DSTC... makes it much worse to deal with in terms of $$$$ as its VIN locked.

      and that does not matter if it's a physical problem like a broken solder joint or failed pump.

      crack it open and fix it.

      That I would not do with a VIN locked component because if you totally FUBAR it the car ain't moving until you pony up a grand to the dealer. Yeah you could mess with the solder joints but without a decent understanding of electronics I would not.

      I don't suspect the dealer is going to pop it open and solder anything, so what is there to lose?
      Not that I assume that is the issue.
      Seems like not attempting a fix for fear of having to pay the dealer, simply results in having to pay the dealer? What am I missing?
      Again, all theoretical as I am aware it could be unrelated to the abs module.

      So if you fix it, you may or may not have to pay the dealer a grand. If you take it to the dealer you will definitely hand them.your wallet...Lol hmmmm, choices...

      I don't have much faith in dealerships "fixing" anything either. They are just usually more like a jiffy lube with access to factory parts. Parts swappers...

      The techs they hire are green as freshly sprouted kale, mostly hired because of insurance requirements in relation to driver's licensure.

      An indie with a VIDA/DiCe (specialist) should be able to figure it out with a lot better outcome. At least I hope they haven't locked it up that much for your year/model.

      If you break it more you can't have a company like xemodex refurb it...

      The dealer may be part swappers but they have access to the software downloads in VIDA indies don't... like for keys and such... It sucks I know but that's what you get so you deal with it.

      this is the only risk.
      if you crack it open they may not accept it to rebuild it.

      It needs to be scanned.
      like I said, intermittent engagement of the ABS sounds like a wonky wheel speed sensor.
      it may be pump related. Swapping a pump is super easy. takes an hour.

      anything passed that and you probably need to send it off for rebuild unless you're super handy with an o scope and soldering iron.

      Actually, I have plenty of experience with electronics repair outside of automotive applications, so that should not be an issue. Trying to figure out how to get Win 7 pro so I can use the aftermarket dice gadget - not so much.

    21. #19
      I posted the link to my VM.
      and the DICE unit you wanted to buy.
      it's a nearly perfect factory clone, only lacks bluetooth.

    22. #20
      Wondering if it's worth a bleed before hitting the dealer for codes?

    23. #21
      as in hydraulic bleeding?
      probably won't affect it.

      I'd take it to the dealer or an indy with vida, get the errors and see what's up.
      Order your own DICE unit from china, wait the three weeks and have your own.
      super handy, you pretty much can't diagnose anything in these cars without, short of glaring mechanical brokenness.
      If you're in a place with rust I've seen tone rings get so nasty that the wheel speed sensors can't discern between teeth, the occasional errant reading trips out the ABS system. A good cleaning with a wire brush and good as new. just make sure to cover the sensor so it doesn't accumulate all the nasty rust dust.

    24. #22
      Yes I have been looking into the links. Much appreciated. It took 10 minutes for me to realize what VM meant, so there would be a learning curve.

      your biggest obstacle to repairing the module is actually getting it open. xemodex uses a cnc mill to do it clean.
      I've seen people open them with dremels. Doable if you're cautious.

      but I still think that it's not a module problem. if it were you'd be getting a brake failure stop safely message in the DIM, because that's what happens when it drops off the canbus.

    26. #24
      Also....your car picks up its speed input from the abs module, if it's not working properly, it can effect the trans as well. You need to start by pulling codes with vida to determine the actual problem. May be worth going to a dealer simply for codes and nothing else.

      I did not know this thanks. And yes, at this point the plan is to find a dealer who will provide the codes without a lot of grief.

      Before you crack open the ABS control module, consider servicing the motor first (black coveer bolted to the pump). You can do that yourself and often, it just needs a clean.
