duncan351 Posted August 29, 2023 Report Share Posted August 29, 2023 I used GP PWM function on my new cooling control. Set my frequency which is constant. Chose "Switch Logic" to Cond 1 or 2 1 Cond ECT > Sw Cond 2 There is no option for the AC output (INJ Dr# 7) nor AC Rquest (DI #8) How do you get ECU to activate fans when A/C is turned on or Compressor clutch is activated?

Confused Posted August 29, 2023 Report Share Posted August 29, 2023 Press X on your GP PWM table and set up your other axis to AC output state, then you'll get two columns for your speed. Here's an example - my output is inverted - 0 is full on and 100 is full off. Quote Link to comment Share on other sites More sharing options...
Adamw Posted August 29, 2023 Report Share Posted August 29, 2023 You could also do like below. Then your activation temp, hysteresis and "on with AC" is all taken care of by the normal engine fan settings. Quote Link to comment Share on other sites More sharing options...
