TCCU periodically monitors the input and output while the system is in operation. When a fault is detected, the
trouble code is stored into TCCU memory.
If the ignition switch is turned to “OFF”, TCCU stops monitoring for input and output, however, when the ignition
switch is turned to “OFF” before shifting completes, TCCU continues monitoring for input and output required for the
shifting.
