Refer to COMPONENT LOCATION (without ICC) or COMPONENT LOCATION (with ICC) for detailed installation location.
WHITE-7 TCM TCM 
WHITE-8 ECM
  • For purposes including improving the feeling when shifting speeds and preventing drops in engine speed, control signals are exchanged between the ECM and TCM, and real-time cooperative control is performed according to the vehicle driving conditions. (Engine and CVT integrated control)
    • Engine and CVT integrated control signal
      NOTE:

      General term for the communication (torque-down permission, torque-down request, etc.) exchanged between the ECM and TCM.

  • The TCM receives the following signal via CAN communications from the ECM.
    • Engine speed signal
    • Accelerator pedal position signal
    • Closed throttle position signal
  • The TCM transmits the following signal via CAN communications to the ECM.
    • Malfunctioning indicator lamp signal
Refer to COMPONENT LOCATION for detailed installation location.
