Code C12FE Description

The C12FE code indicates a problem with the ABS pump pressure loss in the vehicle's anti-lock braking system. The ABS pump is responsible for maintaining the correct pressure within the system to ensure optimal braking performance. When this code is triggered, it typically means that there is a leak or malfunction in the system that is causing a loss of pressure, which can compromise the effectiveness of the ABS system.
