A cross-platform crate with FFI bindings to allow for complex vehicle ECU diagnostics.
This crate is a work in progress, and ECU compatibility may vary! This crate goes by the KWP2000 and UDS specification, but some ECUs choose to deviate slightly from the official specification!
- Easy to use (Check the examples folder)
- Implements UDS, KWP2000 and OBD2
- Hardware API for accessing common OBD-2 adapter types (Passthru)
- FFI bindings for use in C/C++ projects! (Check the examples folder)
- Safe to use (Cannot inadvertently send incorrect requests to the ECU)
- Parsing support - Where possible, data is returned in data structures, being interpreted from the ECU's response, rather than just bytes which have to be manually interpreted
- ISO-TP transport layer, LIN, J1850 and DoIP is work in progress at this time
- Diagnostic servers (For KWP2000 and UDS) automatically handle disconnects from ECU
- Optional diagnostic server event receiving for logging internal server events
ISO9141 - OBD2 is a legal requirement on all vehicles produced from 2002, allowing for reading of sensor data, reading and clearing standard DTCs, and reading basic vehicle information. OBD2 is designed to be safe and simple, and does not write data to the ECU.
ISO14230 - KWP2000 is a advanced diagnostic protocol utilized by many vehicle manufacturers from 2000-2006 (Superseded by UDS).
Unlike OBD2, KWP2000 allows for much more complex operations, which could potentially cause damage to a vehicle if used incorrectly.
A few examples of features allowed by KWP2000 are
- ECU flashing
- Clearing and reading of permanent DTCs
- Manipulation of ECU communication parameters
- Low level manipulation of ECU's EEPROM or RAM
- Gateway access in vehicles which have them
The specification implemented in this crate is v2.2, dated 05-08-2002
ISO14429 - UDS is an advanced diagnostic protocol utilized by almost all vehicle manufacturers from 2006 onwards. Like KWP2000, this protocol allows for reading/writing directly to the ECU, and should therefore be used with caution.
The specification implemented in this crate is the second edition, dated 01-12-2006.
