How to Use GODIAG ECU GPT Boot AD and J2534 Device?

In this post, we will mainly introduce a new GODIAG product- GODIAG ECU GPT Boot AD Programming Adapter.

What is GODIAG ECU GPT Boot AD?

It is a professional adapter which is equipped with a short-circuit-proof BOOT resistance board connection line to protect the ECU, and works with J2534 devices/ECU programmers (Foxflash, PCMTuner…) and PCMFlash software to read and write ECU data in OBD2 Bench or GPT Bench method (without disassembling the ECU) or in Boot method (with disassembling the ECU).

What’s the difference between Godiag Adapter and other adapters?

Godiag ECU GPT Boot AD has the features below.

Support GPT to read and write data without disassembling the ECU.
Support ECU opening BOOT method to read and write data
Support ECU conversion to OBD2 mode to read and write data
Equipped with BOOT resistance board connecting cable [anti-lost resistor design]
Support RESET, BOOT, CNF1, GPT1, GPT2, 5V, 3.3V, VPP, GND.
Support PCMFlash automatic control of ignition power supply
Support manual ignition power control
CANbus is equipped with a switch to freely select the 120Ω resistor
ECU dedicated connection terminal.
The ECU interface cable is labeled

GODIAG ECU GPT Boot AD ECU Connector Functions:

1.Supports standard OBD2 protocol equipment to perform diagnostic function.

2.Supports J2534 devices to perform ECU data reading and writing.

Only Scanmatik 2 PRO for PCMflash allows to form GPT1, GPT2 signals necessary to work with Module 71.
Other devices Scanmatik OpenPort 2.0, Mongoose JLR, MongoosePro JLR, Teradyne GNA600 (VCM 1), Mazda VCM 2 supports OBD2 or BOOT 53 mode to read and write ECU data.
