Hi everyone,

I'm planing to do some DIY with my Lexus GS450h from 2007.

The first steps are pretty simple, adding Arduino + bluetooth + relay to open/close door function + remote start (pre-heat the car and cool down interior during hot weather).

The whole project is bigger than that, but I'll start with the basic functions. It will include GSM connection to the car, Android APP to control the car functions like AC, and so on...

Can anyone point out some website where I can find door module wiring diagrams, start/stop button wiring diagrams and some other diagram for the future?

My usual voltmeter pinpointing/testing is not accurate and sometimes lead to unnecessary problems. Not to talk about time consuming.

Thank you all.

 

we used to use, ww.bbbindustries.com or www.bbbind.com but I think they blocked off the free access. You can try searching or pay for there service, but they had diagrams of the complete car.

 

I've been using the official Lexus service information at https://www.lexus-tech.eu/ (works at least in Europe). It is not free, but costs about 3-4€/hour. In one hour you can save quite many diagrams to your PC...

Are you planning to hack to the car's CAN bus or just play with the wirings?

The first step would be to play with the wirings, playing with CAN bus is my dream.

Do you have experiences with that?
