DTC 23

CIRCUIT DESCRIPTION

DTC Detection Condition:

Vehicle speed sensor circuit sends a signal to the cruise control ECU as a 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 given illustration).

This signal is converted inside the combination meter and sent as 4-pulse signal to the cruise control ECU.

The ECU calculates the vehicle speed from this pulse frequency.
