Question
How to diagnose faulty diagnostic tool USB port?
Answer
Test USB connection stability and measure port voltage output.
Explain
A faulty USB port prevents data transfer or tool charging. CHEPQ diagnostic tools include USB port testing functions that check connection stability (no data dropouts) and voltage output (5V ±0.2V), helping identify loose ports or internal circuit failures—replacing the port restores tool connectivity.
