Precautions for Diagnosis
1. The battery voltage range on the car: +9~+36V DC;
2. When testing some special functions, the operator must operate according
to the prompts and meet the test conditions. For some models [special
functions], the conditions that need to be met are: engine water temperature
80℃~105℃, turn off headlights and air conditioners, Keep the accelerator
pedal in the released position, etc.;
3. As the electronic control systems of different models are more complicated,
if you encounter situations where it is impossible to test or a large amount of
test data is abnormal, you can search for the ECU of the vehicle and select
the menu through the model on the ECU nameplate;
