That's interesting that with two axle air it uses doppelt front and back.

I wonder why they have dual sensors but maybe it works better to have a non linear resistor or reverse ramp for one system versus the other.

I have seen the voltage of the height sensor for air spring but never have seen the output of the headlight sensor option on my scanner.
