Gateway Module: what it does and what each make calls it

What does this module do?

The gateway module bridges the vehicle’s different data buses and decides which message crosses to which bus. Diagnostic traffic passes through it as well, so a problem in the gateway can make every individual module look unreachable.

What do the makes call this module?

The name of a module doing the same job changes from make to make. The names below are the actual definition names used under this type in the CarCoding scan map (38 distinct names):

Which makes define it?

The map holds 51 definitions for this type, spread across 24 make groups:

Address and protocol

Every definition in the map is marked as UDS. 31 of the addresses are 11-bit CAN identifiers (three digits, such as 7E0) and 20 are 29-bit extended identifiers (such as 18DA10F1). The most frequent addresses for this type are: 710 (6), 17F40028 (2), 17F40029 (2), 17FC0010 (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.

Gateway 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.
