Designation of Schrader TPMS protocols: "PA66GF35" is meaningless

[emuzychenko]

One of Schrader TPMS protocols is designated "Schrader TPMS EG53MA4, PA66GF35". "PA66GF35" is meaningless here because this is the designation of the sensor housing material (polyamide type 66, 35% of glass fiber), and has no relation to the device itself.

Usually, such designation is framed with angle brackets: ">PA66GF35<". Cases of most automotive electronic devices are made from polyamide (PA6/PA66) based plastics, so such designations on the cases are very common.

This is a very good bit of information to have. Thanks! And some Toyota/Lexus sensor is mentioned with this in #1165
too :)

Thank you for the fix!

Throughout the existence of Direct TPMS, most documentation on standards and protocols of the system remain inaccessible. :( It is not surprising that enthusiasts are trying to rewrite all the designations from the device cases in order to identify them as accurately as possible.
