Circuit/System Description
WARNING: This page is about a different car, the 2007 Suzuki XL7. However, it is still accessible from the selected car via links, so may be relevant.
The three linear pressure control (PC) solenoids are installed directly in the transmission valve body (V/B) and use pulse width modulated signals from the transmission control module (TCM) to control transmission pressures. The TCM varies the current to the PC solenoids from 0.1 amps, for maximum pressure to 1.1 amps, for minimum pressure. Internal current monitors within the TCM provide feedback in order to determine actual PC solenoids current draw.
