This specialized module performs a
comprehensive health analysis on 4-pin and 5-pin
electro-mechanical relays commonly utilized
across modern automotive electronics networks.
The diagnostic software routine cycles the target
relay ten consecutive times, aggressively testing
circuit resistance, contact continuity, and
operational consistency within each individual
cycle. If any single cycle fails the stress test, the
unit delivers instant visual feedback via a red LED
indicator; conversely, a green LED illuminates if
the relay functions perfectly across all cycles.
