=== Mode 1 ===

Each module maintains a set of tables containing live data as well as stored parameters. When a device issues a Mode 1 request to a module, it provides the number of the table being requested. The module responds by transmitting the requested table number, followed by the contents of the table (the PCM differs in that it does not transmit the table number, only the table data). The exact contents and structure of the table depend on both the table in question, and the module. Tables are numbered sequentially, however most modules have less than 10 tables. Requests for table numbers higher than the total number of tables on a given module will not receive a response{{Dubious}}. The table below illustrates the full structure of a Mode 1 request.

When an invalid table number is requested, the response differs depending on the module the request was issued to. When an invalid table is requested, the PCM will simply not respond. When an invalid table is requested from the BCM, it will send a Mode 13 response. When an invalid table is requested from the ABS/TCS module, the response will be an empty table (the requested table number, followed by 0 bytes of data). The table below illustrates the full structure of a Mode 1 request.
