Code C2171 2014 Toyota RAV4 Description

The C2171 diagnostic trouble code (DTC) for a 2014 Toyota RAV4 indicates that the transmitter ID for the tire pressure monitoring system (TPMS) has not been registered with the vehicle's computer. The TPMS is a safety feature that monitors the air pressure in each tire and alerts the driver if there is a significant drop in pressure, potentially preventing accidents and improving fuel efficiency. When the transmitter ID is not registered, the TPMS will not function properly, and the vehicle may not be able to provide accurate tire pressure readings to the driver.
