SUPPLEMENTARY RESTRAINT SYSTEM (SRS) 6 C: Inspection, repair and replacement required in SRS system after accident 1. The complete airbag system consists of fol- lowing components. Those cannot be ser- viced/repaired, hence should be replaced in case of any damage/deployment irrespective of ‘if found ok’ . a) Driver airbag b) Passenger airbag c) Seat belt assembly d) Front impact sensors e) Side impact sensors f) Side airbags g) Side Curtain airbags (Inflatable Curtains) h) Wiring harnesses i) SRS ECU j) Clock spring k) Passenger airbag deactivation switch 2. If Frontal Airbags, seat belt pretensioners are deployed during collision, following compo- nents must be replaced irrespective of ‘if found ok’ . a) Driver airbag b) Passenger airbag c) Front Seat belt assembly RH & LH d) Front impact sensors -LH & RH e) Cockpit (with PAB provision & wiring har- ness) f) Wiring harness g) SRS ECU h) Clock spring 3. If Side Airbags, curtain airbags are deployed during collision, following components must be replaced irrespective of ‘if found ok’ . a) Deployed Side airbag(s) b) Deployed Curtain Airbag(s) c) Front Seat belt assembly for the side(s) that deployed d) Side impact sensor(s) for the side that de- ployed e) SRS ECU f) Wiring harness 4. In case of Curtain Airbag deployment follow- ing components also needs to be replaced ir- respective of ‘if found ok’ . a) Roof trim b) A –pillar trim c) B – pillar upper and lower trims d) C – pillar trim e) Rear grab handle f) Front grab handle g) All related trim clips h) Sun visor 5. After any type of vehicle accident, thoroughly inspect all the airbag system components for any damage or deformation. Replace components as required. Thorough inspection of their mounting locations is also strongly recommended after any accident. 6. If any damage or deformation is observed on any airbag system components, these components MUST be replaced even if they are not de- ployed/ fired in the accident and are showing healthy status when checked. 7. Special attention should be paid to mounting sur- faces and mounting brackets mainly for SRS ECU, Front impact sensors and Side impact sen- sors as they are extremely critical for perfor- mance of the system. If these cannot be repaired to their original condition, the original panel(s) MUST be replaced . 8. In case of damage to SRS wiring harness/wires, they must not be repaired but replaced. 9. If steering wheel and steering column are de- formed or if the steering column is collapsed in an accident replace these components. 10.The accident Vehicle should be inspected to identify component deformation or structural de- formations, damages for repair or replacement. e.g. Vehicle front, side, rear structure, seats, un- derbody components etc. 11.Check for DTC’s using diagnostic tool and trou- bleshoot to clear all the DTC’s detected. WARNING ‘ If the SRS warning indicator in the instrument cluster illuminates continuously, it means there is a malfunc- tion in the system, vehicle needs to be diagnosed so take the vehicle to nearest TATA Authorized Service Center’.
