How to Remove a Chrysler's Body Control Module (BCM)

by Kyle Sanstrom

The body control module, or BCM, in a Chrysler vehicle controls all of the body-related functions such as the interior lights and door chimes. This module is a computerized component, and when it fails a number of symptoms can occur. These symptoms include flashing interior lights and randomly sounding chimes. Replacement BCMs are available from auto parts stores, automotive salvage yards and licensed Dodge and Chrysler dealerships.

Step 1

Park the vehicle on a flat surface, turn off the engine and apply the parking brake.

Step 2

Determine the BCM's location using a repair manual specific to your vehicle's model and year. The BCM is in a different place on each Chrysler model, but it is usually mounted underneath the dashboard on the passenger or driver's side.

Step 3

Depress the locking tabs on the BCM's electrical connector and disconnect it. Remove the mounting screws holding the BCM to its mounting bracket using a 3/8-inch ratchet and a metric socket. Remove the BCM from the vehicle.
