In this article, we will bring you an in-depth review of GODIAG GT105 Box.


We’ll divide this article into 5 parts:

Part 1. Ford 2016- Smart AKL Programming (alternative to Xhorse Ford AKL Cable)

For Ford AKL progrmaming by VVDI, OBDSTAR or Autel, we need to disconnect car battery, connect to negative pole via OBD PIN 5, and connect positive pole via OBD PIN16.


For example, to program by Key Tool Plus and GT105, we need to disactivate alarm firstly:

1)Enter IMMO menu, prepare two VVDI Smart Keys, and enter Ford Mondeo 2016- AKL menu

2)Check if alarm is on.

If not, battery disconnection is not required; If yes, disconnect positive pole as instructions, and connect GT105 to battery as below.

Read data by key programmers after dash gets on. For part of models like A6L or Q7, we can read data even dash is black.


2)Toyota needs sync after engine/immo ECU replacement, or key programming for some models needs short-circuit PIN4-PIN13.
