C0614Right Park Brake Actuator Stuck On
- Generic OBD-II code · Chassis
- Can trigger limp mode
- How the car detects it
- C0614 is set when the right parking brake will not let go, or when the module cannot confirm that it has. To release, the motor runs in reverse; Advics treats the force as released when, after a minimum run of roughly 200 ms, the current has settled, and then lets the motor run on briefly to restore pad clearance. If that pattern never appears, or the motor stalls, the right side counts as stuck on. Bosch also uses current monitoring to spot abnormal behaviour and may command a release on its own. Causes are mostly mechanical: a seized piston or spindle nut, pads rusted to the disc after standing, or a jammed gearbox. ZF notes that the actuator must be wound back with a scan tool before service. Driving off overheats the right rear brake.
