SMART ENTRY AND START SYSTEM (for Start Function), Diagnostic DTC:B2283

DTC Code DTC Name
B2283 Vehicle Speed Sensor Malfunction

DESCRIPTION

The skid control ECU converts the wheel speed sensor signals into a 4-pulse signal and sends it 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 main body ECU. The main body ECU determines the vehicle speed based on the frequency of this pulse signal.

Tech Tips

When the main body ECU is replaced with a new one and the cable from the negative (-) battery terminal is connected, the power source mode becomes IG-ON mode. When the battery is removed and reinstalled, the power source mode that was selected when the battery was removed is restored.
