DTC B2283 VEHICLE SPEED SENSOR MALFUNCTION

CIRCUIT DESCRIPTION

DTC Detection Condition:

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 vehicle speed based on the frequency of these pulse signals.

The power source control ECU and the combination meter are connected by a cable and BEAN. This DTC is output when: 1) the cable information and BEAN information are inconsistent; and 2) a malfunction is detected between the vehicle speed sensor and the combination meter.

Wiring Diagram:

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 will not operate normally.
