# etnga-obd: mapping Toyota eTNGA vehicle diagnostics

> etnga-obd maps the OBD-II diagnostic surface of Toyota eTNGA vehicles, including the bZ4X, Subaru Solterra and Lexus RZ. It records UDS over ISO-TP addresses, gateway sub-targets, decoded telemetry formulas and selected broadcast CAN frames, with confidence levels for individual findings.
