Code C1A48 Lexus Description
The C1A48 code for Lexus vehicles indicates a G Sensor Malfunction. The G sensor, also known as the lateral acceleration sensor, is a crucial component in the vehicle's stability control system. It measures the lateral forces acting on the vehicle during cornering or sudden maneuvers and sends this information to the vehicle's computer system, which then adjusts various systems to help maintain stability and control.
