The remote controlled door lock circuit of Buick-Century
The left-front lock switch is in parallel with right-front door lock, when the lock switch is at lock position, the lock relay will drive the 4 lock motors to lock all the doors; when the switch is in unlock state, the relay will make right-front, right-rear and left-rear door open, and the left-front door is opened by the driver.If there were no remote modules, such as in Figure 2,actions likeopening the door or locking the door would be done by keys or door lock switches.
