Code C1415 Description

The C1415 diagnostic trouble code (DTC) refers to a Rear Speed Sensor Right Output Malfunction. This code indicates that there is an issue with the output signal from the rear speed sensor located on the right side of the vehicle. The speed sensor is a crucial component of the vehicle's anti-lock braking system (ABS) and traction control system. It is responsible for measuring the speed of the wheel and providing this data to the vehicle's electronic control module (ECM) to help regulate braking and traction.
