OBD JScan for Android

Quick summary

OBD JScan is a free Android diagnostic tool from Clever Software designed for Jeep vehicles. It reads standard Diagnostic Trouble Codes (DTCs) and displays real-time data from the car’s sensors. The app can also modify certain vehicle configurations and identify onboard module information such as VIN and part numbers.

Main capabilities

• Adjust vehicle configuration options (for example: tire dimensions, axle ratio, daytime running light behavior)
• View and stream live sensor data across the vehicle in real time
• Clear and retrieve diagnostic trouble codes and share reports
• Detect and report module details including VIN and component part numbers
• Communicate with a wide range of onboard systems, for instance: automatic transmission, HVAC, ABS, radio, sway bar, and steering column

Vehicles known to work

• Jeep Liberty / Cherokee (KK family) and similar models
• Jeep Wrangler (JK series)
• Jeep Grand Cherokee (WK family)
• Additional Jeep variants are also supported; capability can vary by year and equipment

Security gateway and extra hardware notes

Some Jeep models implement security gateways that restrict access to certain modules. On those vehicles, extra hardware or a gateway bypass method may be required before JScan can read or change secured modules. Confirm whether your specific year/model has gateway restrictions before expecting full functionality.

Adapter recommendations and alternatives

• OBD ELM327-style adapters are supported and generally recommended for use with the app
• If you need another option, consider third-party services such as MCD — many offer toll-free support for setup and troubleshooting

Final tips

Before using JScan, verify compatibility with your exact model and year. Some advanced functions may require additional adapters or bypass hardware, and behavior can differ between model families.
