TPMS: Test Before You Touch
Test Before You Touch is almost a direct result of the “make inoperative” provision in the Motor Vehicle Safety Act as it applies to the Federal Motor Vehicle Safety Standard No. 138, Tire Pressure Monitoring Systems. In layman’s terms, the provision states that if a vehicle comes into a facility with working TPMS, it must leave the facility with working TPMS. A shop cannot knowingly disable TPMS in the vehicles that it services.
Nissan Tech Tip: TPMS Diagnostics
If the TPMS/LTPWS warning light is illuminated (continuously or flashing), the TPMS/LTPWS system can be diagnosed by turning the ignition to the “OFF” and then to the “ON” position. If the TPMS/LTPWS warning light is continuously illuminated (not flashing), the TPMS/LTPWS is operating normally and has detected low tire pressure in one of the tires.

Subaru TPMS: Better Service These Direct Systems With Dedicated TPMS Tools
Subaru first started experimenting with TPMS in its vehicles in 2004 with the Subaru Outback and Subaru Legacy. The Subaru B9 Tribeca was outfitted with TPMS in 2006 and the automaker added TPMS to all of its other models in 2008. The TPMS on Subarus are direct systems. In order to properly service and reset these systems, it’s important that a shop invests in a TPMS tool that can interface through the OBDII port.
