Understood. My point is that this system must not have scored that great as my friends Taco is a 2006 and his brothers is a 2007 and they do not have the complicated system that mine has yet they have the exact same motor. I remember when we had this discussion about how even toyota will not repair parts in this unit but instead recommend an entire new unit. In my opinion that is silly. Especially if it is just the accumulator or accumulator pump or something like an o-ring that has failed. I believe the price of that unit new is 1,700 dollars plus somewhere around 600 or so to install it. I was willing to attempt the install but then I was told that you have to have the sst tool to bleed all the solenoids in the unit correctly. I am going to be looking at new or close to new vehicles so that I can have warranty coverage for these new systems that can not be worked on.
The reason it wasn't included in the Tacoma (it is built into the Land Cruisers, Tundras, 4Runners, FJ Cruisers, GX470/460, ect) is probably the same reason the 2014 Tacoma uses the older 1GR-FE engine with Single VVTi, the the Tundra, 4Runner, and FJ Cruiser all benefit from the Dual VVTi motors. Not to mention that while the Tacoma is a 120/150 Platform vehicle it is not fully boxed like the 4Runner, GX470/460, FJ Cruiser, and Land Cruiser Prado.
You technically need a Scantool to bleed the vehicle in general because of the ABS system, this is not new; its been around since ABS was introduced. Most people just get by without having to bleed the solenoid pack because more than half the time air doesn't make it into the units.
As for serviceability, that's nothing new either. I don't see Cadillac, Toyota, Lexus, or any one else that offered this type of system (which is basically n all hybrids, higher end luxury cars and/or a variation using a vacuum pump for GDI engines) offering anything but the whole unit. Its just easier for the manufacturer to sell and train technicians to replace an entire unit that to bother training them to diagnose, disassemble, repair, and rebuild units.
Welcome to the new age of electronic wizardary that is built into even the cheapest of vehicles. Its only going downhill now that manufacturers want to traditional physical braking connections, create self-driving/self-parking cars, catering to every little new technology to gain the upper end over their competitors.
People are only now starting to realize what they've got themselves into because all this technology has been around for about a decade, but now its starting to age and break down and their Manufacturer warranty won't cover the repairs. What's worse is most technicians have refused to learn about newer technology because they are intimidated, afraid, or do not want to spend the time/money to invest in repairs for such technologies. But they have little to no choice, this isn't the days of carburetors and single injector throttle body systems. You need to understand Computer Networking, Programming (to a mild extent), how to use Digital Oscilloscopes, complex interactions of sensors/outputs/modules, ect.
The truth is ANY vehicle you buy in the last ten years has expensive electronic components that will cost you an arm and a leg to repair when they do go bad.
