Powertrain Control Module (PCM) Inputs
PURPOSE
The Engine Controller (EC) located in the powertrain control module (PCM) shares two signals with the transaxle controller (TC). These two
signals are the vehicle speed signal (received from the vehicle speed sensor), and an ignition voltage signal. The vehicle speed signal is used by the
transaxle control module (PCM/TC) to determine vehicle speed for transaxle shifting. The ignition voltage signal is used as the Power-up signal to
activate the transaxle control module.
LOCATION
