Having spent many hours online looking for the correct initialisation code to use Torque Pro with my Alphard, I have finally found a bluetooth reader / code combination that works on this model. It only took four months 🤣
So, I am using the VGate iCar Pro BLE 4.0. I have a no-name chinese ELM reader that doesn't work and another that I will give a go as soon as I get it out of the other car as the VGate doesn't seem to bluetooth connect with my head unit.
In Torque Pro for the initialisation string I used the preset for Toyota (JDM, Celica, Corolla, Camry) which is:
ATIB 96
ATIIA 13
ATSH 8113F1
ATSP A4
ATSW 00
I hope this might help someone.
