Pcm (ECM/TCM)
WARNING: This page is about a different variant/trim than selected.
The ESP sends request data, such as torque reduction, the number of fuel cut cylinders, and the IEBM control request, to the PCM (ECM & TCM) through CAN bus line. The PCM (ECM) conducts the fuel cut according to the request from the ESP and then retards ignition timing. The PCM (TCM) maintains current gear position during the IEBM control in order to prevent a Kick down shift.
