• The PCM inputs throttle opening angle, engine speed, engine torque, engine coolant temperature. to the TCM.
• The TCM operates shift and TCC controls based on the throttle opening angle, and controls line pressure and other based on the throttle opening angle and the engine torque.
• The TCM outputs reduce torque signal, range signal, turbine speed, ATF temperature signal, and TCC signal to the PCM.
• If there is an open or short circuit in the CAN wiring, the system determines that the CAN is abnormal and switches to fail-safe mode.
