Mercedes Benz W230 SL350 SRS Airbag Control Module 230 820 0985 - Used Original Part
Diagnosis and Common Symptoms
The SRS (Supplemental Restraint System) control module, often referred to as the N2/7 unit in Mercedes-Benz technical literature, acts as the brain of the vehicle's safety network. Failure in the W230 SL-Class is frequently signaled by the persistent "SRS" or "Restraint System Defective" message on the instrument cluster. Common diagnostic fault codes include B1000 (Internal Control Module Hardware Fault) or various communication errors where the Star Diagnosis System (SDS) cannot establish a handshake with the unit. Physical failure often occurs due to voltage spikes during battery jumps or internal capacitor degradation. If your scanner shows a "Control Unit Defective" status that cannot be cleared, the hardware must be replaced.

Frequently Asked Questions
Q: What symptoms indicate failure? A: The most common sign is a permanent SRS warning light on the dashboard that prevents the vehicle from passing safety inspections. Technically, you will likely see a B1000 "Internal Fault" code that remains "Current" and cannot be deleted via OBDII diagnostics.
Q: Does this require coding? A: Yes. In the Mercedes-Benz ecosystem, SRS modules are VIN-locked and contain specific configuration strings for the vehicle's equipment (such as seat occupancy sensors and belt tensioners). You will need a Xentry/DAS system or a high-level bidirectional scan tool to perform the "Initial Startup" and coding procedure.
Q: Is this original? A: Yes, this is a Genuine Mercedes-Benz component. We do not sell aftermarket or "reproduction" safety modules, as they often lack the precise accelerometer calibration found in the original factory hardware.
