DTC 23 VEHICLE SPEED SIGNAL ABNORMAL

CIRCUIT DESCRIPTION

Detection Item:

The signal from the vehicle speed sensor circuit is sent 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 installation).
ECU calculates the vehicle speed from this pulse frequency.
