It provides the definitive terminal pinout mapping necessary to test battery voltage, chassis ground, signal ground and multiplex comm lines(CAN High and CAN Low) Attempting to back probe the DLC3 connector without the factory specs poses a high risk of shorting live power circuits and permanently damaging the ECU.
