C0614 indicates that the park‑brake control module has detected a malfunction in the right‑side electric park‑brake actuator – the motor or mechanism is not moving as expected. The code is set when the module commands the actuator to apply or release and the expected change in circuit resistance or position does not occur. It is a chassis‑system code that concerns the parking‑brake actuator rather than the engine computer.
The DC motor inside the right park‑brake actuator can seize, have burnt windings, or have a broken gear train, preventing movement.
Corrosion, rust, broken cables, or a damaged lever can jam the actuator so the motor cannot move it even though the motor is functional.
An open circuit, short, or poor ground at the actuator connector prevents the proper voltage and current from reaching the motor.
A failed fuse, fusible link, or relay that supplies power to the park‑brake circuit can cause the actuator to remain stuck.
The module that commands the actuator can fail to provide the correct output, though this is less common than the above causes.
Severely low system voltage can make the actuator appear stuck, but the code normally reflects a persistent mechanical or electrical fault rather than a simple voltage dip.
No. The park‑brake actuator, its wiring, and the park‑brake control module are far more likely sources. Replacing the PCM is rarely necessary for this code.
It is not advisable. The right park‑brake may stay engaged, causing excess drag, overheating of the brake, or a sudden release while driving.
A weak battery can make the actuator sluggish, but the code is set when the system detects a true mechanical or electrical failure, not just low voltage.
Most manufacturers service the actuator as a complete assembly; some allow replacement of just the motor unit, but the common repair is to replace the whole actuator.
