The 2013 Toyota Highlander came equipped with an array of components—including a door lock wiring diagram—that make it safe and efficient to use. This wiring diagram allows technicians, owners, and even DIYers to quickly understand how the electrical system is configured and to troubleshoot any issues that may arise with the vehicle’s door locks.
When you first look at the 2013 Toyota Highlander Door Lock Wiring Diagram, what do you see? A full schematic of the vehicle’s electrical system with components such as relays, switches, fuses, and wiring harnesses labeled all in one place. It can be confusing to follow, but if you break it down into its component parts, understanding the diagram isn’t so daunting.
Let’s first take a look at the relays. Each relay controls the current for a given component. For instance, the power door lock relay located near the left door lock actuator controls the current for the left door lock. Whenever a door is locked or unlocked, this relay sends current to confirm the action.
Next, let’s cover the switches. These switches are the ones found on your vehicle’s doors. There are two different types of switches: a push switch and a pull switch. The push switch is used to lock the door. When pressed, it sends current to the power door lock relay, triggering it to send a signal to the door lock actuator. The pull switch is used to unlock the door. When pulled, it interrupts the current sent by the power door lock relay, thereby unlocking the door.
In order to fully understand and work on your 2013 Toyota Highlander’s door lock system, having the wiring diagram handy is essential. Whether you’re a technician working on a customer’s car or a DIYer looking to diagnose an issue, it’s important to understand how the wiring works and how each part functions. With the help of the 2013 Toyota Highlander Door Lock Wiring Diagram, you’ll be able to quickly identify and troubleshoot any problems with the vehicle’s door locks.
