Vehicle Speed Sensor: Description and Operation

The electronic speedometer sends the vehicle speed signal (TN signal) to the electronic accelerator control unit for the cruise control function. The control unit uses it only for cruise control. If the vehicle speed signal fails, neither the electronic accelerator function nor the drive torque control is adversely affected.
