OBD JScan is a free Android app developed by Clever Software that allows Jeep owners to read standard Diagnostic Trouble Codes and Generic Live Data. It can access all modules available on the vehicle, including ABS, Steering Column, Automatic Transmission, Radio, Sway Bar, HVAC, and more. With JScan, you can easily read, clear, and share vehicle trouble codes, view live data from all sensors in the vehicle, and change vehicle settings like tire size, axle ratio, DRL settings, and more. It also allows you to identify modules, VIN, and part numbers. The app supports several Jeep models, including Jeep Wrangler JK, Jeep Grand Cherokee WK, and Jeep Liberty/Cherokee KK, among others. However, some models require additional hardware to bypass security gateways. OBD JScan supports and recommends OBD ELM327 adapters.
