Code C1427 Description

The diagnostic trouble code C1427 indicates an actuator pump motor malfunction. This code is typically associated with the vehicle's anti-lock braking system (ABS), which utilizes the actuator pump motor to control hydraulic pressure within the braking system. The actuator pump motor is responsible for generating the necessary hydraulic pressure to operate the ABS, which helps prevent the wheels from locking up during hard braking or slippery road conditions.
