Hi, I would like to thank everyone in this tread for the good information,
On Sunday I took the module out and soldered the joints, turned out to be quite an easy job. I would recommend it as a first port of call if your tracs light is coming on and off, after reading all the posts I was quite confident that this was the cure. So far no lights and car went through the MOT with no problems. Thanks again, Ian |

For what it's worth, I've noticed a very similar problem that affects Jaguars too. My XJ8 has the "stability control fail" warning light on most of the time and so I recently found a "how-to" to fix it.
Jag Lovers It seems to be very similar to what has been mentioned here. Perhaps the ABS units were assembled in Taiwan for both cars ? I thought I would only need the saw, soldering iron, glue, clamp for the Jag but perhaps it'll come in handy for the Volvo too ? |

There are similar problems for VW owners with Ate control modules.

I would also like to thank everyone who has posted here. I've just done mine on the S80 T6, whether it works or not is somethng else, but it must be said that trying to do it without removing the airbox is a waste of time. Also, try and get someone with skinny forearms to get the ABS box off.
The two main input solder joints were obviously not right, they looked frizzed and rough, a quick dab with a bit of solder had them looking like new, I also wizzed over any other points that looked large enough to take the heat, but I don't really think the problem stems from them, it's the main ones that take bigger current and so degrade the joint. Opening the box was a pain though, trying to do it without damaging it seems to be impossible, I ended up just nibbling the flanges off the edge with a steel rule, getting it in, bending it back till the flanges snapped off, then again on the inner flanges. Be VERY careful if you do this though, once you start nibbling away at the inner flange, a slip with the tool can trash the unit. It's only silicone hoding it on but it's a pig to shift. I'll refit tomorrow and see how it all goes. Thank again. |

Well it worked! All codes gone, traction control is now switchable and all the lights have gone out. Well pleased.

abs light still on after diy repair
Just spent yesterday doing the diy repair. I've just refitted and taken my c70 out for a spin and sadly the abs light remains on. Shame was worth a go. At least I didnt pay for an exchange unit if its not the unit at fault. I'm going to disconnect the battery now for 30 mins and see if it clears, but that's a long shot.
Back to the drawing board and probably to a garage as not sure where I go from here ? Maybe needs a new pump, or senso.....r or the abs controller has a fault beyond a bad solder joint ? |
