Here’s a rundown of the top technical service bulletins related to TPMS from 2012.

Ford
TSB Number: 12-6-2
Vehicles: 2009-11 Ford Edge and Mercury MKX
Condition: Corrosion on the lip of 22-inch wheels and whiskers/vents on the tire’s bead seat may cause the TPMS to illuminate.
Solution: Disassemble the rim and tire and clean the rim flange and tire bead with a Scotch-Brite pad.

GM
TSB Number: 00-00-90-002K
Vehicles: All GM vehicles with direct TPMS systems
Subject: Adjusting tire pressures under warranty
This TSB is an advisory stating adjustment of tire pressures is not a warranty procedure. It also defines a cold tire as one setting for at least three hours and advises against the use of non-GM tire sealants.

Infiniti
TSB Number: 12-29 (Also Nissan TSB Number: 10114B)
Vehicles: All Infiniti (Nissan)models with TPMS
Subject: Damage to TPMS sensors
Infiniti pulls no punches here! The luxury brand of Nissan tackles two of the leading causes of sensor damage. Infiniti tells technicians that deep well, long reach air chucks can break and bend stems on TPMS sensors. It even advises against the use of locking chucks. The TSB recommends the use of shallow chucks without extensions. While some automakers have stated that some sealants are compatible with their TPMS sensors, Infiniti states that some sealants and propellants can crack the housing of its sensor. The pictures in the TSB are hard to dispute.

Infiniti
TSB Number: 12-046A
Models: 2013 JX35
Subject: TPMS registration procedure
This TSB is of little consequence to technicians who use an aftermarket scan tool to register IDs with the TPMS module. The procedures discussed concern new hardware and software for the Consult III scan tool.

Jaguar
TSB Number: JTB-001654
Subject: Loss of pressure during inflation
Jaguar issued this TSB to advise technicians to be careful with valve stems during inflation or valve cap removal. The TSB advises strongly against metal valve stem caps that can cause galvanic corrosion. It also advises that if the customer has used non-approved valve caps, all four or five sensors should be replaced.

Lexus

Toyota Scion
TSB Number: SB0001-12
Subject: Inflation pressure temperature compensation
Scion released this TSB to inform technicians how ambient temperatures can influence tire pressure. The release includes a chart that plots temperature and pressure. This TSB will help you determine the correct tire pressure in all seasons. SB0001-12 is another “must print” TSB for technicians.

Volkswagen
TSB Number: 4412-02
Models: 2012-13 CC
This TSB informs technicians that some CC models may experience a loss of signal from a single or multiple TPMS sensors. The only solution is to replace all four sensors with updated sensors from HUF.
