Power Lock Motor
POWER LOCK MOTOR
| Refer to COMPONENT INDEX . |
All the door locking motors are protected and managed by the BCM.
Inside the actuators are Positive Temperature Coefficient (PTC) elements that are in series with their motors. The PTC elements permit thermal protection in the event that the BCM continues to supply current to the motors due to a fault. The resistance of the PTC element increases as its temperature increases, consequently interrupting the electrical circuit.
The locking motors are integrated to each of the door latch assemblies with the exception of the tailgate. The tailgate lock actuator is attached to the rear tailgate and handle assembly and is serviced separately.
