A 2016 Hyundai i20 has a 200mA parasitic battery draw, 130mA above normal, likely caused by multiple modules failing to sleep, and the technician needs a systematic diagnostic workflow to isolate the source.

Workarounds Described

• disconnecting the data link connector to check for moisture or corrosion
• unplugging the AC control module temporarily to test for internal shorts
• pulling fuse Hyundai STOP LP to see if draw drops below 100mA

Implied Software Gaps

• Guided diagnostic workflow for parasitic draw that integrates multimeter data and vehicle specs to suggest which modules to disconnect next
• Reference database of expected sleep currents per module per vehicle model

ParasiticDraw Pro

A guided diagnostic app that helps automotive technicians systematically isolate parasitic battery drains. It provides step-by-step testing workflows, records baseline and after-fuse current readings, and logs module sleep behavior to pinpoint the culprit module.
