Code C1103 Infiniti Description

When the sensor rotor rotates, the magnetic field changes. It converts the magnetic field changes to current signals (rectangular wave) and transmits them to the Anti-Lock Brake System (ABS) Actuator and Electric Unit (Control Unit). The ABS Actuator and Electric Unit monitors the ABS Wheel Sensor. The ABS Actuator and Electric Unit sets the OBDII code when the ABS Wheel Sensor is not to factory specifications.
