Hi,
Not sure if this belongs in HVAC or Aftermarket ECU section, sorry if its wrong.
So I have hooked up pin 6 to my MaxxECU so that it knows when AC is running.
Initially when it is hot in the cabin and the AC is going full beans it works as expected.
Strangely when it starts to come down in temp and fanspeed decreases to maintain lets say 21 deg C the AC ON signal is lost through pin 6.
I really cant understand why because when looking in channel 52 on the climate control the compressor is still activated in this scenario.
I also had a look at channel 20 which shows the voltage output to compressor and it is steady in at 12v, and the magnetic clutch is engaged.
So what is happening here that is confusing the ECU to think that compressor is switched off when reaching desired temperatur in the cabin?
Is there some resistor or other black magic electricity that needs to be added to the pin 6?
This of course wouldnt bother me if the engine did not almost stall when coming to idle.
This is how pin 6 is configured in MaxxECU.
Pin 6 -> GPO7 (converted to DIN3)
DIN3 -> AC request/idle up
