DTC B2283 Vehicle Speed Sensor Malfunction

DESCRIPTION

Detection Condition:

Detection Condition:

The main body ECU and the combination meter are connected with a cable and the CAN communication line. DTC B2282 is output when signals, transmitted through the cable and the communication line, do not match.

The skid control ECU converts these signals into 4-pulse signals and sends them to the combination meter. After these signals are converted into a more precise rectangular waveform by the waveform shaping circuit inside the combination meter, they are then transmitted to the main body ECU. The main body ECU determines the vehicle speed based on the frequencies of these pulse signals.
