AW4 tiptronic control

[rubensx]

ok, This diagram IS NOT THE FINAL

Only created based in the cobalt code (thios code is not done, no work properly in my tests)




Please, this is a diagram for start a help and NOT A FINAL SOLUTION.
I need a help with a code and logic... without help I'll stuck here...


Explain the diagram:

Arduino take the current status about the solenoids A and B (in AT or MT mode) and show the gear in leds (7 segment, not implement OLED at now).

With these information the arduino knows the gear and in MT mode on, takes the control of the solenoids with a last information of the gears...

This point the TCU is not without a power, but his control about solenois is cut and don't makes difference (the relays take TCU off from gears solenoids) and the arduino take the control...

With this feature, maybe (i guess) we stop the CEL with MT system...

The choose of the arduino is about simple to program, and are "realtime" response...


ok... is it...

Cobalt, if you can send me a light about this (if it's the right way) thank you again


IMPORTANT: This code is a public code, please refer the users and the people who help the project in code and posts in another foruns, thank you
