Doubt it. Your main ECU will not like having the ABS ECU missing from the bus.

I'd pretty much guarantee it. It's on my '99 100-series, my '05 4Runner and my '08 ES350. Good news is that they seem to work well up to about 150K and then the failures start to show up after that. Probably depends also on how much stop-n-go driving you do vs. highway driving, since using the brakes is the primary duty cycle of the system.
Marc - Please refresh my memory on the issues that you were having that indicates a failure in the system. Are you seeing any problems yet with the 100 or the Lexus? Probably not enough miles on those yet. Some of my vehicles are a similar vintage and I want to know what to watch for - thanks!

My particular 'failure' was that the boost pump/motor was cycling on/off every 10 seconds. The system was not holding the pressure created by the pump. This was a failure either in the accumulator or maybe some kind of check valve in the pump. I don't know for sure. I only know that the brake system is no longer having this issue now that I replaced the motor/pump/accumulator assembly. I have not had any indications of any problems in the Lexus or the 100. I would suspect the most likely failure would be in the motor, either from the brushes wearing down or bearings failing. This would likely result in some noisy hints prior to the motor completely failing.
