^ ^ I agree. I'm not convinced the computer is the true culprit in many of these "computer-replacement fixes". In many years of working on cars I have replaced one sensor, and no computers. The rest of the failed sensors were actually bad sensor connectors. They may feel tight, but 5-7 years of vibration, heat, and dirt made for a bad or loose connection inside. Sometimes unplugging and replugging various sensors is all that is needed to make the various failure lights go away. Slight bending of the internal contacts in lots of connectors has saved me big over the years.

I suppose it is possible the vibration from the antilock valves could dislodge something on the ABS computer board. I have seen cracked solder joints in computers before. Easy to fix if you can find them. You can bet that if/when this problem crops up on my Sequoia, there is going to be a LOT of unplugging, crimping, cleaning, and computer-case-opening going on long before I putter into Toyota to let them drain my wallet of $1000-$2000 for a new $89 ABS /Trac computer.
