Symbols
These two symbols are special versions of the Solid State Switch. They represent serial data inputs and outputs. Serial data consists of coded
groups of voltage pulses transmitted at HI speed. These pulses cannot usually be measured with a Digital Voltmeter. There are cases however
where procedures in System Diagnosis may describe such measurements. A Scan tool can often read and display this data.
