How to use Launch X431 V Diagnostic Tool to read a 2017 Subaru WRX TPMS tire pressure data stream? Now I’m gonna make a quick demonstration for the procedure.
Connect Launch X431 V tablet with Subaru OBD, press
Local diagnose >> Subaru >> OK >> 16 pin socket >> North America
Confirm vehicle information, press “Yes”>> System selection
As seen, we can perform lots of services here, like transmission, tire pressure monitor, driver’s control center differential, brake control, body control, occupant detection, impact sensor, airbag, etc.
Tire pressure monitor(TPM) >> Read data stream >> Select options, press “OK”
Now we can find the detailed pressure values and standard range of selected options here.
Press “Graph” to view the waveform of each TPMS data.
Launch X431 V 8 Inch Scan Tool is quite helpful for daily work of mechanics. I had used it to diagnose and do maintenance for many of my customers.
