Code C1712 Infiniti Description

The C1712 code for Infiniti vehicles indicates that the front left transmitter is malfunctioning. In Infiniti vehicles, the transmitter is a crucial component of the tire pressure monitoring system (TPMS). The TPMS is responsible for monitoring the air pressure in each tire and alerting the driver if there is a significant drop in pressure. The front left transmitter specifically communicates with the vehicle's onboard computer to provide real-time tire pressure data.
