DTC 21,23 Vehicle Speed Sensor Circuit

CIRCUIT DESCRIPTION

The vehicle speed sensor signal is sent to cruise control ECU as vehicle speed signal.
The rotor shaft is driven by the gear of the transmission.
For each rotation of the shaft, the vehicle speed sensor sends a 4-pulse signal to the combination meter.
This signal is converted inside the combination meter and sent as a 4-pulse signal to the cruise control ECU. The ECU calculates the vehicle speed from this pulse frequency.
