I recognize that, but I did search and this is the only one that also mentioned a recent caliper replacement.

While the series of indicators seems to be common based on my reading, I'm trying to determine if there is any way I can lay blame on Firestone for causing a problem while replacing the calipers.

I have service scheduled tomorrow with Toyota, but if the OP, or anyone, could say "oh ya, they obviously did X and should do Y to fix it," that would be helpful. If it's dumb luck and i'm out $2,500 to replace the module, then so be it. I just thought the chances of it happening to at least one other person meant that maybe it wasn't random, but related.

Thanks.
