Geely ECU Modules and Addresses

Observations from the map

The Geely map ranks 20 with 32 definitions; the largest module types are: camera module (3), steering module (3), transmission control unit (3).

32 of the addresses use 11-bit CAN identifiers and 0 use 29-bit identifiers. 1 definitions have scan priority 1; priority decides which module a scan starts from.

The map contains 3 safety-critical module definitions (ABS/brakes and airbag). Opening a diagnostic session on these can turn on a warning lamp; the vehicle must not be driven during the operation.

See the modules in your vehicle

With an ELM327-based BLE OBD2 adapter, CarCoding scans the vehicle’s modules, reads fault codes from those it can reach and explains every code in plain language. Which modules are reachable depends on the make and on the vehicle. The app is free to download.
