Tire Pressure Monitoring Systems

The Challenge

In response to the NHTSA (National Highway Traffic Safety Administration) requirement that 100% of the automobiles manufactured for use in the United States be outfitted with TPMS by September 2007 (20% by 9-1-2005 and 70% by 9-1-2006), Honda requested GLA to comply with the mandate. Before the mandate, all tire and wheel assemblies were fitted with a standard rubber valve stem. Under the new mandate, a TPMS valve with a sensor attached must be installed in each tire and wheel assembly. Each sensor must be checked for proper installation and operation. All torque and pressure measurements must be recorded by unique sensor identification number.

How GLA Addressed the Challenge

GLA selected a supplier to design and integrate a system to meet Honda's needs. The solution integrated the TPMS installation process into GLA's existing process. The system utilizes a series of DC nut runners to tighten the stem to the wheel. The sensor is then activated to read the sensor ID which is recorded into a database along with the torque value. The last step of the process automatically identifies the TPMS valve and performs a full functional test before shipment. The ID and tire pressure are then recorded in the database.

The Benefits of the GLA Solution

GLA's system offers Honda a high level of part traceability along with the highest level of quality. GLA currently builds 1,000 TPMS units per day and will increase this number to over 10,000 units per day within the next two years. The system is flexible and has the capability of running multiple styles and types of systems. GLA provides the following modular assemblies:
