SUPPLEMENTARY RESTRAINT SYSTEM (SRS) 20 ON VEHICLE REPAIR REMOVAL 1. Disconnect the battery connection. 2. Remove lower “B” pillar trim. (For procedure refer “B” pillar trim removal procedure in CAB section.) 3. Disconnect the electrical connection from side impact sensor. 4. Loosen and remove the mounting bolt and re- move the side impact sensor from “B’ pillar. FITMENT For fitment follow reverse procedure of removal. NOTE The FIS and SIS are of same type in vehicle. III AIR BAGS DRIVER AIR BAG (DAB) The driver airbag module is located in the steering wheel and its function is controlled by the SRS ECU. A bag within the module inflates to protect the driver in the event of a collision severe enough to deploy the system. The driver airbag module connects to the steering column wiring harness via a rotary coupler called as clock spring. Within the driver airbag module is a squib which, when given the correct current by the SRS ECU, inflates the airbag by initiating a chemical reaction. In deployment, the airbag inflates within a fraction of a second and then deflate at a controlled rate as the driver body regions; typically head and chest interact with airbag. Vents in the airbag control its deflation. The SRS ECU regularly applies a test current to the driver airbag squib to confirm continuity of the igni- tion circuitry.
