Code C2181 Description

The diagnostic code C2181 indicates that the transmitter ID 1 signal is not being received by the vehicle's system. This typically refers to a communication issue between the tire pressure monitoring system (TPMS) sensor/transmitter and the vehicle's receiver. The TPMS system is responsible for monitoring the tire pressure and transmitting this information to the vehicle's computer for display on the dashboard. When the transmitter ID 1 signal is not received, it can result in inaccurate tire pressure readings being displayed to the driver, potentially leading to unsafe driving conditions.
