How can I RE program an MX sensor when is tells me it is a duplicate? I bought four, I programmed three of them without an issue. the fourth one was programmed with a duplicate ID number. I don't see how to erase it and re program it to get a new unique ID number. Thanks
This means the fourth sensor you programmed has the same ID with one of rest three sensors.You can program the sensor again by input the different sensor ID(manual input).Or you can use auto create or copy by activation to program the sensors.If you use Auto create or manual input(not the IDs stored in ECU) to program your sensors,you have to relearn you vehicle after your mounted the sensors to reset the TPMS.
