Sensor localization using an assembly line tool

A diagnostic system for verifying functionality and performing mapping of one or more wireless sensors in or on a wheel of a heavy-duty vehicle on an assembly line, the system comprising:

• one or more assembly-line tools provided along the assembly line, each assembly-line tool comprising one or more antenna systems arranged to interrogate one or more wireless sensors integrated into or on a wheel of the vehicle, wherein each assembly-line tool is arranged in use to:
• automatically locate on the vehicle and verify a function of the one or more wireless sensors;
• and
• interrogate at least one of the one or more wireless sensors to perform a wireless sensor reading;
• and
• pair sensor reading data with a tire identifier (ID),
• pair sensor reading data with a vehicle chassis identifier (ID),
• wherein the diagnostic system maps one or more wireless sensors using wireless sensor readings and provides mapping information for the one or more wireless sensors to a gateway/receiver of an electronic control unit of the vehicle.
