Renault automotive and Bendix aeronautics provided the engine, automatic transmission and anti-lock braking electronics for the Jeep Cherokees (XJ), Comanches (MJ) and Wagoneers (SJ) from 1986 to 1991. Renix (as the join venture was called) had a serial data protocol for system diagnostics that was never published. Thanks to the hard work of Phil Andrews of the RenixPower forum and Nick Grisley of NickInTimeDesign, the protocol was reverse engineered. This project expands on their work to create engine and vehicle diagnostics for my 1988 Comanche, Little Bo' (Jeep).
Additional thanks to my sister, Lauren, for coming up with my Jeep's name.
