C0613 — Right Park Brake Actuator Performancestuck Off

Generic OBD-II · all makesChassis

C0613 indicates that the right electronic parking‑brake (EPB) actuator is not moving to the applied position when commanded. The control module detects a performance fault because the actuator remains in the released (off) state despite activation requests.

Symptoms

What causes it — most likely first

1. Failed right EPB actuator motor or gear set

The actuator’s internal motor or gear train can wear or seize, preventing the brake from applying.

2. Open or shorted wiring to the right EPB actuator

Damaged harness, corroded connectors, or a broken wire can interrupt the drive signal to the actuator.

3. Mechanical binding of the right parking‑brake mechanism

Corrosion, debris, or a seized cable/lever can stop the actuator from moving the brake into the applied position.

4. EPB control module internal fault

A hardware defect in the module’s driver circuit may prevent it from commanding the actuator correctly.

5. Software or calibration issue in the EPB system

Out‑of‑date firmware or an incomplete adaptation can cause the module to misinterpret actuator feedback.

How it's diagnosed

  1. Retrieve all stored codes and freeze‑frame data; confirm C0613 is present and note any related codes.
  2. Visually inspect the right EPB actuator wiring harness and connectors for damage, corrosion, or loose pins.
  3. Using a scan tool, command the right EPB actuator to apply and release while monitoring actuator current and position feedback.
  4. Measure the actuator motor resistance and verify it matches the manufacturer’s specification.
  5. Check the mechanical parking‑brake components on the right rear for binding, corrosion, or seized cables.
  6. If all hardware checks pass, verify EPB control module software version and perform a module reset or reprogramming as directed by service information.

Frequently asked

Do I need to replace the vehicle’s main PCM/ECM to fix C0613?

No. The code is specific to the EPB subsystem; the main engine control module is rarely the cause. Replacing it will not resolve the actuator performance fault.

Can I continue driving with this code active?

It is not advisable. The parking brake may not hold the vehicle, creating a safety hazard, especially on slopes.

Will clearing the code with a scan tool fix the problem?

Clearing the code only removes the stored fault; the underlying mechanical or electrical issue will cause the code to return.

Is this a common failure on certain vehicle platforms?

Electronic parking‑brake actuator failures are relatively common on vehicles equipped with EPB systems, particularly as mileage increases.
