I have the infamous codes and the funny pedal as well as the annoying buzzing noise on this one. I had the ABS pump assembly replaced before on a Sequoia and a Lexus before, I assume the replacement is the same on these. I just need the instructions just in case since this is a hybrid and will require removing the inverter. Thanks

You do not have to do this but if it makes you feel better then do it. You only have to remove it when working on something the with high voltage side of the system and this is on the 12 volt side.

I attached the process for what they call the booster pump assembly which appears to be the ABS pump as they show a picture of this at the end. I have never heard it called this but it is a Toyota.

Thanks again.

I don't blame you. Even though I have been trained on hybrids I still get nervous when looking at them.

Can you help me with a couple of pictures of the brake light switch? After connecting the brake pedal am seeing that the switch button isn't touching the pedal even when its fully released, just want to make sure I installed correctly.

No problem. I attached the process to adjust the brake pedal and the installation of the switch. It has all the measurements needed to get them adjusted correctly.
