3 min readNov 2, 2023

Currently, it is not possible to read and write all ECUs through the OBD2 diagnostic interface or without opening the ECU, there are still many ECUs that need to open the cover to read and write data. The GODIAG ECU GPT Boot Adapter ECU Connector can be used for ECU PINOUTs of different manufacturers and brands according to the wiring definition. It can not only be simulated as a standard OBD2 diagnostic interface, but also supports ECU connection via GPT Bench without disassembling the ECU or Boot mode with disassembling the ECU.

With the Pinout connection diagram, it’s easy and fast to connect GODIAG Adapter, J2534 device/ECU programmer (SM2 Pro, OpenPort 2.0, Foxflash, PCMtuner…) and ECU for ECU data reading and writing. Here obdexpress.co.uk offers the methods to get ECU Pinout diagram below.
