Can you please answer these questions....
Why today's modern cars has 7v from 12v at each of the door open close status signal wire??? Example, Toyota Glanza, Taisor and Hydryder etc etc.
When any door is closed, it stays at 12V. After some 20 seconds, it drops to constant 7V??
Why this delay? Why not directly drops to 7V?
Can you please make new videos about this?

[@K-H-diag]

Hi my friend. I will do my best to make a video for that as soon as I can.

[@tnamen1307]

@@K-H-diag yes I'm really curious to know.. what's the significance of 7v from 12v? Why the delay? Why not constant 12v??? What is the advantages?
