Accomplishing a 100% successful read and write of the DCM 3.7 via OBD has been demonstrated effectively with PCMtuner, including a successful EGR OFF operation incorporated within the software.

Image 1. To initiate the process, bring the PCMtuner to your vehicle. Establish a connection between the device, the OBD2 diagnostic port, and the computer. Once connected, proceed to launch the PCMtuner application.

The subsequent steps involve the critical phase of data read.

The culmination of the process is marked by the successful completion of the writing phase, indicating that the task has been carried out successfully without any hitches.

This demonstration attests to the seamless and effective functionality of the PCMtuner in conducting DCM 3.7 read and write via OBD, illustrating a hassle-free and successful endeavour.
