DTC B2282 Vehicle Speed Signal MalfunctionDTC B2283 Vehicle Speed Sensor Malfunction
DESCRIPTION
DTC Detection Condition:
DTC Detection Condition:
The power source control ECU and the combination meter are connected by a cable and the BEAN. DTC B2282 is output when: 1) the cable information and BEAN information are inconsistent; and 2) a malfunction is detected between the vehicle speed sensor and combination meter.
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.
