If the sensors are already programed and the vehicle model and year range is listed on the menu , it should be able to read them.
If the sensors are new blank un-programed TPMS sensors of a Brand other than the Autel brand MX sensors it won't be able to read and program other brand blank TPMS sensors that have not been programmed with an ID yet. If it has 4 new unprogrammed blank Autel MX sensors they should be programmed before installing on wheels or with all air pressure vented from tires.
If you recently updated the software on the TS408 see if it can read TPMS sensors on other vehicles.
