1. COMBINATION METER





(a) Measure the voltage according to the value(s) in the table below.














(b) Waveform 1 (Reference) : Using an oscilloscope:





HINT:
When the system is functioning normally, one drive wheel revolution generates 4 pulses. As the vehicle speed increases, the width indicated by (A) in the illustration narrows.
