OBD-2 DLC Breakout Box, How to Use

in this video you will see ingenious ways to make your own diagnostic equipment with these procedures and plans have been tried an adult bill but given the nature of the detailed work needed needed we make no guarantees it is ultimately up to you you of skills technician or DIY genius to make it work work using the obd2 dlc breakout box the obd2 dlc breakout box is a device or tool that allows for all kinds of testing on the obd2 DLC connector it is not a scan tool and it doesn't communicate with the vehicle ECM it is only a measurement tool there are many scenarios to use the obd2 dlc breakout box such as testing the communication signals or listening to the network traffic between the different modules in the car also to test chassis and sensor ground issues using voltage drop measurements which is built into the obd2 dlc breakout box power tests that can determine if the alternator or battery is at fault start a tests that measure the drain on the battery as the starter engages and even running compression tests based on battery draw from the starter motor here are the scenarios where the obd2 dlc breakout box is useful scenario 1 looking at the inter module network signals or between scanner and ECM the car isn't starting due to no spark oil or injector pulse this is important because it'll tell you right away two things imagine that the vehicle doesn't start there are many possibilities for this to happen first you need to know if the ECM is alive how well by initiating your Network call to it using your cheap obd2 code reader so first go to the start network connector or main splice and disconnect all the modules except the ECM you then connect the obd2 DLC breakout box and the cheap code reader right behind it at this time you can view all the incoming and outgoing signals between the scanner and the ECM if the ECM is not responding and it has good power feed and ground you know the ECM is dead but more often than not what happens is that another module or computer brings down the network in cases like that you then start to reconnect each module one at a time at the star Junction while viewing the obd2 DLC breakout box as soon as the shorted module is reconnected the obd2 dlc breakout box laptop graphing voltmeter will show a signal drop the obd2 dlc breakout box will save you the cost of buying an oscilloscope and pinching the obd2 connector wires or damaging it in the process all the other scenarios for using this tool are fully automated on the software so if you need to diagnose the power or grounds it's all done automatically this is a nice tool to have if you want to tackle network power and ground issues the obd2 dlc breakout box usefulness giving that the obd2 connector is standardized will render many years of service to you
