Yes the Toyota dealer has the daig tool as lexus they use tech stream I like the software it only works on Toyota or lexus my subscription for that cost me about 2,000 a year but worth it and is the only way to get the latest ECM updates

There is two systems on the 400h that would need reset one is the hybrid learning which does require a tool and the other is the ICS most of the late 07 and 08 will do it automatically there was an ECM update for those

No I used same diameter line the barb fitting is what will go into the other component the pictures will help out a great deal of. The understanding of it I have a master cylinder to change in a few days so I may go though the drain process as well

Did your tool come with a cable to connect to the OB2 port ?

I have sevral diag tools the cost is way more than a dealer diag my tools cost around 5,000 for each one as there is different tools for diag not sure how far you are from me if u was close I would be more than happy to diag the issue there is a few things we can check when you have the time

Most cheaper tools will read the sensors but not what the ECM is reading so the tool will show everything fine but in the ecm it will not as far as the dome light that is a loose bulb

No I did not go the kit route the best sand paper I could find is made in Germany the finer the better used 3000 plus wet sanding then 3M buffing compound then cleaned the surface sprayed with clear coat I will need to look up the clear coat I used I know it was not cheap

And if the old sensors were not deleted from the ECM before the new sensors were added the ecm is most likely confused I guessing they were not programed correctly or there not the correct sensor not sure if you took a picture of the new ones before they were installed as I would be able to tell you if there correct

I have a tool that can read twice as much information that tool is reading and as always launching a parts canon never ends well I would have diag the issue before the sensors were replaced honestly it will take a high end scan tool to correctly diag those sensors and the ecm that controls them and did you replace them with OEM the only ones I found that work correctly is Denso you can get those on Amazon for about 50 dollars for one

There is 2 bulbs in the running lights one is in the high beam side and the other is on the side

Yes the projectors I replaced with OEM bulbs and yes the running lights I used VLEDs I think they have a slight blue tint for the high beams I went with SYLVANIA 9005 SILVERSTAR ZXE GOLD HALOGEN HEADLIGHT BULB they have held up well I never needed to replace my headlight assembly I just removed them and sanded them and buffed them out and re did the clear coat on them

Figured this may help on the headlight remove there is 2 10mm bolts on top there is 1 10mm bolt under the relay fuse box that just unclips to move out of the way then the last 10mm bolt is on the fender well you will see that once the bumper has been removed

I stayed with OEM HID bulbs upgraded the Halogen bulbs to better Halogen bulbs as far as the maker bulbs go i went with VLEDs there not cheap but there still working the turn single bulbs i stayed with OEM

That is the ABS actuator on the passenger side those make that noise if there is air in the break system or it has not been properly bleed or the fluid is way over due for replacement

That rubber is a vibration dampener
