Code P0500 2AD-FHV RAV4

The skid control ECU outputs a signal that is proportional to vehicle speed. This signal is based on the rotation of the ABS wheel speed sensors. After this, the signal is converted into a more precise rectangular waveform by the waveform shaping circuit inside the combination meter. It is then transmitted to the ECM. The ECM determines the vehicle speed based on the frequency of this signal.

Code P0500 1AZ-FE RAV4

In vehicles equipped with ABS (anti-lock braking system), the speed is determined by the skid control ECU and the wheel speed sensor. The wheel speed sensor monitors the wheel speed and sends appropriate signals to the skid control ECU. The skid control ECU converts the received wheel speed signals into a 4-pulse signal and sends it to the ECM via the instrument panel. The ECM determines the vehicle speed based on the frequency of this pulse signal.
