TPS(or APS) signal which is used for judging driver's intention is received from engine ECU through CAN line. This signal is a criteria signal to determind amount of torque distribution at front/rear wheel with steering angle sensor, wheel speed sensor, break signal.
This code related to communication line between ECU and TCCU is set when CAN signal from ECU can't received for more than 1sec or ECU internal error occur.
If failure is detected TCCU prohibits the ITM control.
