- The output shaft speed sensor detects the front reduction gear speed. The output shaft speed sensor converts the front reduction gear speed into pulse signal and transmits the signal to TCM.
- The vehicle speed signal (meter) is transmitted via the CAN communication from the ABS actuator and electric unit (control unit) through the combination meter to TCM. TCM calculates the output shaft speed based on the vehicle speed signal (meter) and uses it for the diagnosis of each speed sensor and as a backup signal.
