COMMON BCM FAULTS & SYMPTOMS

Body Control Module Problems Explained

The Body Control Module (BCM) is responsible for managing many of your vehicle’s electrical systems. When it develops a fault, it can cause a wide range of issues — often confusing and intermittent.

At BCM Express, we specialise in diagnosing and repairing BCM faults across all makes and models, helping you avoid unnecessary replacements and costly dealer visits.

What Does a BCM Control?

Your BCM manages key electrical functions such as:

Central locking
Electric windows and mirrors
Interior and exterior lighting
Indicators and hazard lights
Immobiliser and security systems
Wipers and washers
Dashboard and warning systems

When the BCM fails, one or multiple systems may stop working properly
