C0610 Right Park Brake Actuator Control Circuit/Open

Check engine lightUsually off
EmissionsNot relevant
Drive cycleNot required
Limp modePossible

C0610 reports that the drive circuit of the right rear parking brake motor is open, so the controller switches its bridge but no motor current flows. Mitsubishi's 2023 Outlander PHEV shows how such a check works under its own code C10B0-01: during apply or release the ABS unit looks for an open motor circuit on the right side and reacts within about one second, then suspends the electric parking brake and hill start assist. Hyundai calls the same fault C2417 on the Ioniq hybrids and replaces a connector extension harness, and GM's PIT5662A wants no more than 6 ohms per rear circuit at the EBCM. None of these makers emits C0610 itself. The right caliper cannot clamp; the left side is C060B.

Likely causes

Right caliper motor connector unplugged, corroded or with pushed-back pins
Broken wire in the harness that flexes with the right rear suspension
Open winding or worn brushes in the right actuator motor
Blown fuse or fusible link feeding the parking brake output stage

Symptoms

  • Parking brake warning lamp and service message
  • Right rear caliper neither applies nor releases electrically
  • Hill start assist or auto hold unavailable
