FORD TRANSIT CUSTOM ALTERNATOR MODULE CODING

BMS Reset & Alternator Coding for Ford Transit Custom Euro 6

Modern Ford Transit Custom vans use a sophisticated charging system controlled by the **Body Control Module (BCM)** and a **Battery Monitoring Sensor (BMS)** located on the negative battery terminal. Simply replacing the battery or alternator without resetting the BCM's memory means the charging system operates using the old component's parameters, leading to overcharging, undercharging, or persistent dash warnings.

• Battery Monitoring System (BMS) Reset: The essential procedure to tell the BCM that a new battery has been fitted, ensuring accurate State of Charge (SOC) calculations and correct charging strategy.
• Alternator Control Module Coding: Where applicable (depending on the specific alternator fitted), programming the BCM to correctly communicate and control the new alternator for optimal voltage regulation.
• Voltage & Current Verification: Using dealer-level diagnostics (IDS/FORScan equivalent) to check live charging data and confirm the system is charging correctly post-coding.
• Persistent Fault Clearance: Clearing related permanent and pending Diagnostic Trouble Codes (DTCs) from the BCM and PCM modules.

We perform this vital electronic configuration at your location, ensuring your Transit Custom's charging system is running safely and efficiently with the correct voltage management.
