B2283

4GR-FSE STARTING: SMART ACCESS SYSTEM WITH PUSH-BUTTON START: B2283: Vehicle Speed Sensor Malfunction

DTC B2283 - Vehicle Speed Sensor Malfunction

DESCRIPTION

The skid control ECU converts these signals into 4-pulse signals and sends them to the combination meter. After this signal is converted into a more precise rectangular waveform by the waveform shaping circuit inside the combination meter, it is then transmitted to the power source control ECU. The power source control ECU determines the vehicle speed based on the frequency of these pulse signals.
HINT:
When the power source control ECU is replaced with a new one and the negative (-) battery terminal is connected, the power source mode becomes the IG-ON mode. When the battery is removed and reinstalled, the power source mode that was selected when the battery was removed is restored.
