Part 3 - Writing the Read DID

1. Run the Read DID Job:

From the Diagnostics screen (Vehicle Networks > Diagnostics). Run the Read DID service. If connected to hardware that is connected to a bench or vehicle, the requested data should be received.

2. Run the Write DID Job:

Now run the Write DID service. The service will write the VIN (or other selected DID) to the ECU with the data provided by the Read DID job. This just shows one simple example. A different ECU could have been selected for the Write DID service. Another variation of this example could include a DPS programming action in between the Read DID and Write DID. This way when the programming is complete, the VIN and other parameters can be put back in the ECU.
