I own a Tata Altroz petrol car which has Idle Start Stop feature which relies on the battery state of charge of the vehicle to operate. Without that value, its highly unpredictable if the car turns off or not cause according to its software, the SoC value should be 75% or above. I have seen the Tata service people hooking their laptop via the OBD port and extracting this value to show and explain the working of ISS feature to me. So I want that PID so that I can keep a watch on the battery for the working of ISS.
