What module controls door locks?

The module that controls door locks is typically referred to as the Body Control Module (BCM). The BCM is a computer that controls various functions in a vehicle, including the door locks, windows, mirrors, and alarm system. It receives input from various sensors and switches, and then sends output signals to control the corresponding functions.

Functions of the Body Control Module

The Body Control Module is responsible for controlling a wide range of functions in a vehicle. Some of the key functions include:

1. Door lock control: The BCM receives input from the door lock switches and sends output signals to control the door locks.
2. Window control: The BCM controls the windows, including the power windows and the window lift motors.
3. Mirror control: The BCM controls the mirrors, including the power mirrors and the mirror adjustment.

How the Body Control Module Works

The Body Control Module works by receiving input from various sensors and switches, and then sending output signals to control the corresponding functions. The BCM uses a complex algorithm to determine the correct output signals based on the input it receives. Some of the key inputs include:

1. Door lock switch input: The BCM receives input from the door lock switches to determine when to lock or unlock the doors.
2. Key fob input: The BCM receives input from the key fob to determine when to lock or unlock the doors remotely.
3. Vehicle speed input: The BCM receives input from the vehicle speed sensor to determine when to lock the doors automatically.

Symptoms of a Faulty Body Control Module

A faulty Body Control Module can cause a range of symptoms, including:

1. Door locks not working: If the BCM is faulty, the door locks may not work properly.
2. Windows not working: The windows may not work properly if the BCM is faulty.
3. Mirrors not working: The mirrors may not work properly if the BCM is faulty.
