DTC B2282 Vehicle Speed Signal Malfunction (Cable- Information does not Match to Bean- Information)
DTC B2283 Vehicle Speed Sensor Malfunction

DESCRIPTION

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.

HINT:
- A voltage of 12 V or 5 V is output from each ECU and then input to the combination meter. The signal is changed to a pulse signal at the transistor in the combination meter. Each ECU controls the respective system based on the pulse signal.
- If a short occurs in an ECU, all systems in the diagram given will not operate normally.
