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

What does this module do?

Door modules locally control the window, mirror, lock and door lighting and talk to the body module. Because the harness passes through the door hinge, wiring fatigue is common in this area.

What do the makes call this module?

Which makes define it?

The map holds 121 definitions for this type, spread across 14 make groups:

Address and protocol

Every definition in the map is marked as UDS. 57 of the addresses are 11-bit CAN identifiers (three digits, such as 7E0) and 64 are 29-bit extended identifiers (such as 18DA10F1). The most frequent addresses for this type are: 74B (3), 17FC0033 (2), 17FC0034 (2), 17FC003E (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.
