SRS and Restraint System Documentation

This factory-authorized manual provides detailed technical descriptions and operational theory for the Supplemental Restraint System and Emergency Tensioning Retractor (ETR) assemblies found in the Mercedes-Benz ML320 and ML350 line. The documentation details the mechanical and electrical architecture, ranging from the control module functions and side impact sensors to the driver-side and passenger-side airbag modules. Readers will find thorough service precautions and inspection procedures for post-collision analysis, covering component replacement schedules and safety guidelines for handling live airbag units and ETR assemblies. Detailed instructions for the clockspring assembly, control module, and side-impact airbag units ensure technicians can identify correct connection and mounting protocols, such as using specific rivets for side airbag installations.

Diagnostic Reference and Electrical Specifications

The diagnostic section documents fault code retrieval processes using the designated Hand-Held Tester (HHT) and necessary adapter cables for the Mercedes-Benz ML320 and ML350 diagnostic link connectors. Comprehensive test steps outline evaluate the driver-side and passenger-side squib resistance, seat buckle switch connectivity, and sensor functionality, including nominal resistance values and multimeter connection points. SRS system electrical resistance for ETR and airbag squibs is documented at 2–5 ohms in the testing charts. The SRS control module ground connection is verified via specific diagnostic pins. Harness replacement is the standard requirement if any wiring components are identified as damaged during fault isolation. All service data shown here is for reference only — qualified technicians and the original OEM documentation remain the authoritative source for any hands-on work. This document is a 100-page OEM technical reference for the 1998–2005 Mercedes-Benz ML320 and ML350, documenting SRS control module diagnostics, wiring diagrams, and critical component replacement specifications.
