JLG Smart System AU3019 1600286 Aerial Work Platforms Controller

The JLG Smart System AU3019 1600286 is an integrated control module for aerial work platforms that manages motor drives, safety interlocks, and operator interface functions. Common failure modes on this unit include power‑supply board degradation (brown‑out or over‑voltage), I/O relay wear leading to loss of signal to hydraulic valves, and firmware corruption resulting in error codes such as “E01” or “E02”. Initial diagnostics should verify the 48 V DC supply voltage, inspect all connectors for corrosion or loose contacts, and review the controller’s diagnostic log for recent fault entries; if a power‑supply failure is suspected, replace the PSU module before proceeding with firmware reflash.[oss-gpt-20b] Post Comment
