DPS ECU ID List

Knowing the ECU ID, request ID, and response ID for the GM modules is useful for reading the module's stored information when using the DPS "Get Controller Info" option. Knowing the IDs is also useful when manually sending commands to the modules. Below is a list of all the GM module IDs.
