Default Pcm low/high fan signal
Does anyone know if once the high speed fan ground signal is activated by the pcm, does it stop sending the low speed fan ground signal? Or does it continue to send both the low and high speed signals at the same time? Thanks

The PCM will send both signals at the same time as long as the motor is above the temp required to enable both fans.
