Pullup, Pulldown, 1M - how to trigger the AC

EMU BLACK / CLASSIC
1

Hello,

Hoping for ideas (since I out of them)… with sensor setup at 1M pulldown when I switch on my AC the AC request circuit goes from 0v to ~2.2v, the challenge is its not enough voltage to trigger the ECU to engage the AC since it needs >4v.

Not knowing any better… I experimented and set #4 to 4K7 Pullup, that bumped the voltage to ~4.6v and the AC worked! When I turn off the AC switch in the dash the AC cutch stays engaged because there is no change in the voltage… what to do?

Is there a combo setting between Sensor Setup and Activation Input, that will make this work?

I think I’ve figured it out… if I used a virtual input and selected the 1.5v (1500mV) as ‘on’ and point it to the analogue input then it would work.
