TCC Solenoid Rationality Monitor

Monitoring procedure
TCM monitors operation (engagement condition) of TCC in response to ON/OFF command to the TCC solenoid using input and output speed sensor signals.

Shift Solenoid "A","B","E" Rationality Monitor

Monitoring procedure
TCM calculates the actual transmission gear ratio from input and output speed sensor signals and monitor it. TCM detects a trouble when the actual transmission gear ratio is not equal to the ratio of each gear as commanded by TCM.
