Code C1339 Description

The Low-Frequency Initiator (LFI) is located at each vehicle wheel house. An LFI unit is mounted in each wheel well of a vehicle to enable the TPMS Receiver Unit to determine the vehicle position of each WE for which it has a stored ID code. Using a LIN communication line to each LFI, the Receiver can activate an LFI to send out an LF message and trigger the WE sensor near its location to respond with an RF transmission. By activating the LFI units one at a time, the Receiver can automatically locate the vehicle position of each WE. For fault detection, the LFI will report back it's operating properly status to the Receiver via the LIN communication line.
