Code C0610 indicates that the control circuit for the right parking brake actuator is detected as open. The module monitoring the actuator cannot see a complete electrical path, so it sets the fault and typically illuminates the parking brake warning lamp.
A broken wire, chafed insulation, or a disconnected harness segment prevents current flow to the actuator.
Internal motor windings or mechanical binding can cause the control module to read an open circuit.
Poor contact at the connector pins creates a high‑resistance or open condition.
The module's driver circuit for the right actuator may be defective, though this is less common than wiring issues.
An internal driver failure in the PCM/ECU can mimic an open circuit, but this is rare and should be considered only after other causes are eliminated.
No. The PCM/ECU is rarely the cause; most often the fault is an open wire, bad connector, or failed actuator.
Yes. A blown fuse in the parking brake actuator supply circuit will appear as an open circuit to the control module.
The code will clear after the fault is corrected and the system completes a successful self‑test, typically during a drive cycle.
Yes. A high‑resistance or missing ground can prevent the actuator circuit from completing, leading the module to set an open‑circuit code.
