      Jaguar SRS (Supplemental Restraint System)/Airbag Diagnostic Trouble Codes (DTCs)

      Jaguar Airbag/SRS Diagnostic Trouble Codes (DTCs): A Comprehensive Troubleshooting Guide

      When the airbag warning light illuminates in your Jaguar vehicle, it indicates a potential issue with the Supplemental Restraint System (SRS). This guide provides detailed information on common Jaguar SRS/Airbag DTC codes, troubleshooting steps, and repair solutions. We also include additional information on related systems to assist you in effectively diagnosing and resolving SRS issues.

      Understanding Jaguar's SRS/Airbag System

      Jaguar vehicles are equipped with advanced SRS/Airbag systems designed to enhance occupant safety. The system includes various components:

      • Restraints Control Module (RCM): Also known as the Airbag Control Module, it monitors the SRS system and controls airbag deployment.
      • Airbags: Including front, side, curtain, and knee airbags to protect occupants during a collision.
      • Seat Belt Pretensioners: Tighten the seat belts to secure occupants upon impact.
      • Impact Sensors: Detect collisions and send signals to the RCM.
      • Occupant Classification System (OCS): Determines the presence and weight of the front passenger to control airbag deployment.
