TCC Solenoid Rationality Monitor

Monitoring procedure

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

Operation





Enable condition





Typical malfunction thresholds






Shift Solenoid #1 Rationality Monitor

Monitoring procedure

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