Jeep Wrangler JK OBD-II support
Model years 1988 to 2026CombustionOnboarded
The OBDb lists 130 parameters for the Jeep Wrangler JK, read from 7 control modules. Real responses from Jeep Wrangler JK cars confirm 77 of them. Drivers have tested model years 2007 to 2025.
Support by model year
A solid mark means a real response confirmed the parameter. A light mark means the car's signalset reads it but no response has confirmed it yet.
Parameters
The parameters of the Jeep Wrangler JK, by group. These are the commands that Jeep added, and the SAE J1979 standard parameters that real cars confirm. Open a group to see each parameter, how Pelican decodes it, and the model years that real cars confirm.
