Code C2115 Lexus Description

The C2115 code for Lexus vehicles indicates a problem with the operation of Transmitter ID 5. In modern vehicles, Transmitter IDs are used in tire pressure monitoring systems (TPMS) to identify each individual tire sensor. When the Transmitter ID 5 operation stops, it means that the system is unable to communicate with or receive data from the specific sensor associated with ID 5. This can lead to inaccurate tire pressure readings, potential safety hazards, and decreased overall performance of the TPMS.
