BCC value Fan #1 = Pusher or Puller fan on TGP/TSTE? 8)
I,m guessing(didn't drive TGP today so can't test)but looked at # of iac steps added and fan 1 has 10 steps and fan 2 has 4 steps.The bigger the fan motor more steps are added.Maybe that will help.
That should be the Radiator Fan. So Pull fan as mentioned. It is wired to Fan one relay. 8)
Ok...
Fan 2 is pusher/intercooler fan
Fan 1 is Main puller/radiator fan
