In simpler terms, this means that the communication between the transmitter and the vehicle's receiver is not functioning properly. The transmitter ID 1 is typically associated with the tire pressure monitoring system (TPMS) in the vehicle, which is responsible for monitoring the tire pressure and alerting the driver if there is a problem. When the transmitter ID 1 signal is not received, it can lead to inaccurate tire pressure readings or a complete failure of the TPMS system.
Common Causes of C2181 2018 Toyota RAV4
- Faulty TPMS sensor
- Weak or dead battery in the TPMS sensor
- Wiring or connection issues between the TPMS sensor and the vehicle's receiver
- Electronic interference affecting the signal transmission
- Malfunctioning receiver unit in the vehicle
