Q3:Some values (turbo, exhaust temperature) cannot be displayed in Shadow OBD2 diagnostic multi-function display.
After OBD2 is standardized, each Parameter IDs (PIDs) has a corresponding position. The value cannot be displayed may be that the PIDs and components are not used in the original factory setting, so the value of the OBD2 display cannot be displayed.

This is because the ECU shuts down and stops sending signals after the engine has been turned off for a period of time. This is normal, don't worry.
Q8: The AFR signal is incorrect or cannot be read.
The value cannot be displayed or the value is incorrect. It may be that the PIDs are not supported in the original factory settings, so the OBD2 display value cannot be displayed. The sensor can be selected by setting the AFR signal source to ensure that the correct information can be read. If the information is still incorrect, it means that the product does not support the signal of the car.
Q9: The mileage of Shadow OBD2 diagnostic multi-function display does not match the mileage on the car.
There will be some errors in the mileage itself. In addition, this product will not automatically read the mileage, so there will be a gap in the first use. The mileage must be manually set in first time. There are "+,–%" in the mileage setting that can be set, and can be fine-tuned according to the degree of error.
