BMW E90 Airbag Control Module 65779184432-02 - Used Original Parts

Diagnosis and Common Symptoms

From the workshop floor, a faulty Airbag Control Module (often called the ACSM or SRS module) is a non-negotiable safety failure. Diagnosis typically begins with a persistent airbag warning light on the instrument cluster and a "Passenger Restraint System Malfunction" error on the iDrive or BC display. A scan with a professional tool like ISTA/D will often reveal specific fault codes pointing directly to module failure, such as "93B2 - Safety battery switch" or a generic but critical "Internal control unit fault". These codes indicate the module itself has an internal hardware or software error and is no longer capable of reliably commanding the vehicle's safety systems in the event of a collision.
