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
The Engine Controller (EC) located in the Powertrain Control Module (PCM).

- • The engine overheats, stalls repeatedly, or misfires under load.
- • You are missing required tools, torque specs, or safe lifting equipment.
- • You are not confident in the next step or safety outcome.
