I haven't found anyone having outside temperature. being a factor in ABS light being intermittent together with 'No Trac' / No ASC . Mine goes off under 55 degrees or so, then comes on above that temp. Is there any good places to look for the cause of this behavior? It has just cooled that much here recently , but it seems to be consistant, off in the mornings then on after it warms outside. Will probably be off all day today, very cool for this time of year.

 

I think the majority of abs modules eventually suffer from the poor solder connection to the abs pump. Could it have a temperature relationship? It wouldn't surprise me, and the more I follow the forums, the less likely I am to be surprised by any electrical faults.
If you are at all handy with tools and can solder, it isn't a difficult project.

I have been reading about this procedure but haven't looked into doing it myself, I was considering sending to the place in Tn. recommended here. Is it a tight fit to get the spots that need fixed? Are there any picture on this site showing how to do this?

 

Think of the combination of a gynaecologist with soldering capabilities and you'll get the picture of the skill set necessary for this operation.

That's not fair Graham, it isn't that bad.

 

It doesn't cost that much to send it out, so if you are uncomfortable take that route,

 

how old is the battery?

 

The skill set mentioned worries me a little,,,,,I've never done much soldering. I don't know how old the battery is, I've only had the car 3 weeks. I'll see if I can find a date on the it tomorrow. It cranks very strong, doesn't seem weak at all.

 

Since you haven't had the car very long it would be a good idea to go to one of the parts stores and have the battery load tested, and have them check for codes also.
As to the abs module, if you can get it out of the car and send it out for a rebuild it will probably money well spent.

 

If you have a multimeter in your toolbox, check the voltage, it's not that hard to do. Checking the date on the battery won't tell you anything.

As for having problems with the ABS, let me say this --

I've had on-and-off ABS issues. What I mean is that sometimes the light comes on (along with the Trac/ASC msg) and then it'll go off after a re-start. It stays off sometimes for months at a time, in fact, it hasn't come on since some time in June and I've driven the car over 6k miles since then -- probably more like 10k, but who's counting?

I did read on this site that one guy noticed his ABS light coming on when it was wet outside -- rainy, humid, etc. I haven't noticed a connection with the weather with my issue.

The first time it happened to me, I freaked! I knew someone else who had the "problem" and paid over $1,500 to get it fixed! WOW!!!! I re-started the car, problem solved for the time being. Since then (that was over a year ago), it's only come on a handful of times (maybe less).

My recommendation -- check the battery first. Replace if necessary. I had to replace mine almost right after I bought the car -- $120 battery for free because the one in the car was under warranty -- it was less than 3 years old and was shot. Don't think the age of the battery will tell you anything, check the voltage or take it to a local shop and have it tested. A new battery can take care of a ton of issues. Secondly, clean the wheel speed sensors -- easy and cheap. Finally, if the ABS light is coming on all the time and you really need to get it fixed, follow the advice in this thread and send it out to have it fixed -- if you can get it out. If you can't take it out yourself, have a trusted (and I stress trusted) mechanic pull it for you. It's not that hard to remove, but I do understand that some people just prefer to have someone else do it, no problem there.

Good luck, and let us know what you find out.

The battery check out fine. I'll move on to cleaning and checking the wires on the wheel sensors this weekend.
