C0613 Right Park Brake Actuator Performance/Stuck Off

Check engine lightUsually off
EmissionsNot relevant
Drive cycleNot required
Limp modePossible

C0613 covers a right actuator that is powered but fails to clamp. The wiring is intact, yet the module never sees the motor turn or the current rise that marks pads pressed against the disc. Mitsubishi gives a concrete case with C10B0-09 on the 2023 Outlander PHEV: during apply the right motor does not rotate, and after ten seconds or more the ABS unit flags it and disables both the parking brake and hill start assist. Bosch patents read clamping force from motor current, so a flat current curve points to a slipping belt, stripped gear or idle spindle; ZF's actuator drives the spindle through a belt and a gearbox. FMVSS 135 requires the parking brake to hold a loaded car on a 20 % grade. No maker publishes C0613; the left twin is C060E.

Likely causes

Stripped gear, slipping belt or broken spindle inside the right actuator
Motor seized by corrosion after water entry
High resistance in the right circuit starving the motor of current
Pads or disc worn far beyond limit, or caliper not calibrated after a brake job

Symptoms

  • Parking brake warning lamp and message
  • Parked vehicle may creep on a slope
  • No motor noise from the right rear when the brake is applied
