WJdiag (Pro & Free) — Android diagnostics for Jeep Grand Cherokee WJ/WG

What it does
WJdiag is a focused scan-tool app for Jeep Grand Cherokee WJ/WG (2002–2004), especially the 2.7 CRD. Paired with a quality Bluetooth ELM327 adapter, it reads/clears faults, streams live data with logging, runs module tests and exposes selected coding tasks that generic scanner apps often miss.
