Installation and Matching Instructions:

1.Fill one liter of transfer case oil (ZF6 speed oil) before installation

2.Do not test run the vehicle after installation. Match it with the original computer (Daotong 431 can also be used, but the steps are the same and the words are different). The matching steps are as follows: enter after the fast test of the whole vehicle is completed → service function I → drive device → VTG transfer case control → VTG calibration → display and control unit transfer case VTG communication is normal I → execute service function → display that VTG has been recalibrated, The new calibration value is stored in the VTG control unit → Display the calibrated calibration value: e.g. the difference between 12.3° and the previous calibration: e.g. - 14.2° → Exit the service function → Test run

Note: If the 4X4 lamp is on during the matching process, the steering angle sensor can be matched in DSC.

3.Professional installation is recommended.
