Diagnostic Trouble Code Chart
Fuel Sender Open Detected (B1500)Vehicle Speed Sensor Malfunction (B2283)
DESCRIPTION
The skid control ECU converts wheel speed sensor 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 combinati ...
