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).
