I have D-in G, pin #38 hooked up to the brake lights of a truck to detect when the brakes are on.
I recieved a report on one truck that the brake lights don't work when the IQAN system is powered off.
Does the impedance change radically when the system is powered down?
the book states 62 kohm pull-down in parallel with 470 pF. I can't imagine that would draw enough power to keep the brake lights from illuminating.
Is this a faulty module? or is this normal and I need to add a large in-line resistor on all trucks in the field wired this way? Are XS2 modules the same way if this is normal?
eta: when I use a multi-meter on another XA2, I get 62K ohms between pin #15 and pin #38, so I am leaning twoards this being a bad module.
