BMW / Mini Footwell Module (FRM) Repair in
Columbia, MD

Driven by Trust, Backed by Experience

Correcting CBAB, A3C1, and A3B4 Lighting Faults

BMW and Mini vehicles are equipped with a control module called the Footwell Module (FRM) that manages many of the vehicle’s lighting and electrical functions. When the module becomes corrupted or damaged, it can trigger fault codes such as CBAB, A3C1, and A3B4 and cause multiple lighting systems to stop functioning properly.


At Smart Turn Auto Repair, we offer specialized FRM module repair and programming to restore proper operation without unnecessary parts replacement.



Why Proper Diagnosis Matters


Replacing modules without proper testing can lead to unnecessary expense and additional programming issues. Our approach focuses on accurate diagnosis and proper module repair, ensuring the vehicle’s electrical systems function correctly before returning it to service.


If your BMW or Mini is experiencing lighting faults or FRM-related error codes, schedule a diagnostic appointment so we can identify the issue and restore proper operation.

Our Diagnostic and Repair Process

Our technicians perform a full diagnostic process to confirm the root cause before recommending repair


This includes:


  • Scanning and documenting all stored fault codes
  • Testing power, ground, and communication circuits
  • Confirming the failure is within the Footwell Module
  • Repairing or reprogramming the module as required
  • Verifying full system operation after repair

Common Symptoms of a Failed Footwell Module

A faulty FRM can cause a variety of electrical problems, including:


  • Headlights not functioning properly
  • Turn signals or brake lights malfunctioning
  • Windows not operating correctly
  • Interior lighting issues
  • Communication faults with the vehicle network
  • Warning messages on the dashboard


In many cases, these failures occur due to software corruption within the module’s memory, often triggered by low battery voltage or interrupted programming events.
