id post in the cooling section but ive tested all my connections to my cooling fan and it all works, relay works, etc. ive looked thru all the param's(S-AUJP) and set everything i could see. i lowered my enable/disable temps for fan 1 as well. when i tested the fan circuit from pin E8 i didnt see any voltage. i tested at the relay and at the ecm. am i missing something? that was the only connection i didnt even cut throughout my harness swap. thanks in advance!

 

How do you have the relay wired?

The efan trigger to the relay from the ECM is a ground trigger.

 

ahh thats what i figured

the trigger from E8 is on pin 85
12V is on 30
load/fan is on 87
ground is on 86

seem right?

 

No.

If you have the ECM connected to 85, then you need a positive ignition signal to pin 86.

 

ok gotcha, i can never understand the schematic for the relay. i have one that i took apart years ago just need to find it. once you said the ecm is the ground trigger it made sense. thanks for your help!
