Door Locking System Wiring
ABOUT YOUR DOOR LOCKING SYSTEM
All power door locking systems have switches to activate doors. These
switches are usually located on the door or center console. Your door lock
switch will have at least 2 trigger wires, one for locking your doors called the
LOCK wire, and one for unlocking your doors called the UNLOCK wire.
You can refer to your vehicle's electrical service manual for details on
location and color coding of Locking/Unlocking wires or you can find them
by tracing the wires from the door switches.
When you push your door lock switch to "lock", your LOCK wire establishes
a connection to either a negative or a positive source, this will be the signal
to your vehicle's ECU to trigger locking signal to the door lock actuator to
lock. Vice versa when you push "unlock" door switch.
Negative and Positive triggers are the two main types of door locking
systems. On a negative trigger system your LOCK and UNLOCK wire uses
(-) negative sources to signal the vehicle when you activate unlock or lock.
In a positive trigger system, your LOCK and UNLOCK wire uses (+) positive
sources to signal the vehicle when you activate unlock or lock.
There are various types of central locking systems, please verify and
confirm the type of door locking system either by multimeter testing and/or
through your vehicle's dealer technical support department. Advanced keys
holds no responsibility for damage to your vehicle by incorrect electrical
connections.
