Shouldn't it complain about ID5 then? There is only one error code on Techstream:Your tire in location 5 has a bad ID. Thats why you are still seeing an error. All "F"s is unlikely to be valid. The two codes you are getting is because of this.
On my 100 series it would go for 1 hour or 60 miles without setting an error if all IDs were valid even if one was not reading. After 60 miles I would get a TPMS ID Error.
On my 200 series it will set an error almost immediately if it cant read all IDs.
