abs trouble

Bumping old thread. I’m guessing the rubbery coating is a conformal coating and is removed either mechanically or by softening with heat. I seem to recall solvents are avoided

This is Ricks area of knowledge, for certain.

you can remove it manually where you need to solder.
After my personal saga of soldering the module 3 times over a period of 5 years (worked for 2 years between the 1st and second solder job and then came on and off again) I had MattyMoo fix one for me and I gotta say I should have done that as sion as the module went bad, especially the second time around.

The benefit of getting a repaired unit is that at least you can cross off the module as possible culprit if the ABS light stays on. In my case I was really starting to suspect something different because resoldering brought temporary improvements, but then the abs light came back.

I recently went thru this experience again too, and had MattyMoo repair my once-upon-a-time repaired ABS module. He did a great job, the ABS system is working fine again -- problem solved.

He is a true wizard with the soldering iron ...

How did you convince him to work on your already-opened module ? He seems quite blunt on his website about not dealing with previously repaired units.

I don't mind repairing them if they're sent in to be repaired, I just don't want them back as cores if an exchange module is sent out. It isn't necessarily anything cut open, all of the ramac and programma cores I get in had previously been cut open but it's clean and you can't tell.

There aren't a million used cores out there like there used to be.
