Which makes define it?
The map holds 177 definitions for this type, spread across 15 make groups:
Address and protocol
Every definition in the map is marked as UDS. 40 of the addresses are 11-bit CAN identifiers (three digits, such as 7E0) and 137 are 29-bit extended identifiers (such as 18DA10F1). The most frequent addresses for this type are: 744 (3), 17FC0035 (2), 17FC0036 (2), 17FC0037 (2).
An address being defined in the map does not mean the module can be read on every vehicle. Reaching modules outside the mandatory OBD-II emissions channel depends on the manufacturer protocol and on the vehicle itself.

Seat Module on your own 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.
Some advanced features require an in-app purchase.
Data source: the CarCoding ECU scan map (ecuDatabase.ts). The addresses and names in the table are definitions from the map; they can differ depending on the hardware and software version in your vehicle.
