CIRCUIT DESCRIPTION
The signal from the vehicle speed sensor circuit 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 through the combination
meter to the cruise control ECU (See the following installation).
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.
DTC No.
Speed signal is not input to the cruise control ECU while cruise
21
control is set.
